DESCRIPTION
The TLC1542C, TLC1542I, TLC1542M, TLC1542Q,
TLC1543C, TLC1543I, and TLC1543Q are CMOS
10-bit switched-capacitor successive-approximation
analog-to-digital converters. These devices have
three inputs and a 3-state output [chip select (CS),
input-output clock (I/O CLOCK), address input
(ADDRESS), and data output (DATA OUT)] that
provide a direct 4-wire interface to the serial port of a
host processor. These devices allow high-speed data
transfers from the host.

In addition to a high-speed A/D converter and
versatile control capability, these devices have an
on-chip 14-channel multiplexer that can select any
one of 11 analog inputs or any one of three internal
self-test voltages. The sample-and-hold function is
automatic. At the end of A/D conversion, the
end-of-conversion (EOC) output goes high to
indicate that conversion is complete. The converter
incorporated in the devices features differential
high-impedance reference inputs that facilitate
ratiometric conversion, scaling, and isolation of
analog circuitry from logic and supply noise. A

TERMINAL FUNCTIONS
TERMINAL
I/O
DESCRIPTION
NAME
NO.
ADDRESS
17
I
Serial address input. A 4-bit serial address selects the desired analog input or test voltage that is to be
converted next. The address data is presented with the MSB first and shifts in on the first four rising
edges of I/O CLOCK. After the four address bits have been read into the address register, this input is
ignored for the remainder of the current conversion period.
A0-A10
CS
1-9, 11, 12
15
I
I
Analog signal inputs. The 11 analog inputs are applied to these terminals and are internally
multiplexed. The driving source impedance should be less than or equal to 1 kΩ.
Chip select. A high-to-low transition on this input resets the internal counters and controls and enables
DATA OUT, ADDRESS, and I/O CLOCK within a maximum of a setup time plus two falling edges of
the internal system clock. A low-to-high transition disables ADDRESS and I/O CLOCK within a setup
time plus two falling edges of the internal system clock.
DATA OUT
16
O
The 3-state serial output for the A/D conversion result. This output is in the high-impedance state
when CS is high and active when CS is low. With a valid chip select, DATA OUT is removed from the
high-impedance state and is driven to the logic level corresponding to the MSB value of the previous
conversion result. The next falling edge of I/O CLOCK drives this output to the logic level
corresponding to the next most significant bit, and the remaining bits shift out in order with the LSB
appearing on the ninth falling edge of I/O CLOCK. On the tenth falling edge of I/O CLOCK, DATA
OUT is driven to a low logic level so that serial interface data transfers of more than ten clocks
produce zeroes as the unused LSBs.
EOC

18
O
I
End of conversion. This output goes from a high to a low logic level on the trailing edge of the tenth
I/O CLOCK and remains low until the conversion is complete and data are ready for transfer.
GND
The ground return terminal for the internal circuitry. Unless otherwise noted, all voltage measurements
are with respect to this terminal.
I/O CLOCK
I
Input/output clock. This terminal receives the serial I/O CLOCK input and performs the following four
functions: 1) It clocks the four input address bits into the address register on the first four rising edges
of the I/O CLOCK with the multiplex address available after the fourth rising edge. 2) On the fourth
falling edge of I/O CLOCK, the analog input voltage on the selected multiplex input begins charging
the capacitor array and continues to do so until the tenth falling edge of I/O CLOCK. 3) It shifts the
nine remaining bits of the previous conversion data out on DATA OUT. 4) It transfers control of the
conversion to the internal state controller on the falling edge of the tenth clock.
REF+
14
I
The upper reference voltage value (nominally VCC) is applied to this terminal. The maximum input
voltage range is determined by the difference between the voltage applied to this terminal and the
voltage applied to the REF- terminal.

DETAILED DESCRIPTION
With chip select (CS) inactive (high), the ADDRESS and I/O CLOCK inputs are initially disabled and DATA OUT
is in the high-impedance state. When the serial interface takes CS active (low), the conversion sequence begins
with the enabling of I/O CLOCK and ADDRESS and the removal of DATA OUT from the high-impedance state.
The serial interface then provides the 4-bit channel address to ADDRESS and the I/O CLOCK sequence to I/O
CLOCK. During this transfer, the serial interface also receives the previous conversion result from DATA OUT.
I/O CLOCK receives an input sequence that is between 10 and 16 clocks long from the host serial interface. The
first four I/O clocks load the address register with the 4-bit address on ADDRESS, selecting the desired analog
channel, and the next six clocks providing the control timing for sampling the analog input.
There are six basic serial-interface timing modes that can be used with the device. These modes are determined
by the speed of I/O CLOCK and the operation of CS as shown in Table 1. These modes are (1) a fast mode with
a 10-clock transfer and CS inactive (high) between conversion cycles, (2) a fast mode with a 10-clock transfer
and CS active (low) continuously, (3) a fast mode with an 11- to 16-clock transfer and CS inactive (high)
between conversion cycles, (4) a fast mode with a 16-clock transfer and CS active (low) continuously, (5) a slow
mode with an 11- to 16-clock transfer and CS inactive (high) between conversion cycles, and (6) a slow mode
with a 16-clock transfer and CS active (low) continuously.

The MSB of the previous conversion appears at DATA OUT on the falling edge of CS in mode 1, mode 3, and
mode 5, on the rising edge of EOC in mode 2 and mode 4, and following the sixteenth clock falling edge in
mode 6. The remaining nine bits are shifted out on the next nine falling edges of I/O CLOCK. Ten bits of data
are transmitted to the host-serial interface through DATA OUT. The number of serial clock pulses used also
depends on the mode of operation, but a minimum of ten clock pulses is required for conversion to begin. On
the tenth clock falling edge, the EOC output goes low and returns to the high logic level when conversion is
complete and the result can be read by the host. Also, on the tenth clock falling edge, the internal logic takes
DATA OUT low to ensure that the remaining bit values are zero when the I/O CLOCK transfer is more than ten
clocks long.
Table 1 lists the operational modes with respect to the state of CS, the number of I/O serial transfer clocks that
can be used, and the timing edge on which the MSB of the previous conversion appears at the output.

(1) These edges also initiate serial-interface communication.
(2) No more than 16 clocks should be used.
(3) No more than 16 clocks should be used.
FAST MODES
The device is in a fast mode when the serial I/O CLOCK data transfer is completed before the conversion is
completed. With a 10-clock serial transfer, the device can only run in a fast mode since a conversion does not
begin until the falling edge of the tenth I/O CLOCK.
MODE 1: FAST MODE, CS INACTIVE (HIGH) BETWEEN CONVERSION CYCLES, 10-CLOCK TRANSFER
In this mode, CS is inactive (high) between serial I/O CLOCK transfers and each transfer is ten clocks long. The
falling edge of CS begins the sequence by removing DATA OUT from the high-impedance state. The rising edge
of CS ends the sequence by returning DATA OUT to the high-impedance state within the specified delay time.
Also, the rising edge of CS disables the I/O CLOCK and ADDRESS terminals within a setup time plus two falling
edges of the internal system clock.
MODE 2: FAST MODE, CS ACTIVE (LOW) CONTINUOUSLY, 10-CLOCK TRANSFER
In this mode, CS is active (low) between serial I/O CLOCK transfers and each transfer is ten clocks long. After
the initial conversion cycle, CS is held active (low) for subsequent conversions; the rising edge of EOC then
begins each sequence by removing DATA OUT from the low logic level, allowing the MSB of the previous
conversion to appear immediately on this output.
MODE 3: FAST MODE, CS INACTIVE (HIGH) BETWEEN CONVERSION CYCLES, 11- to 16-CLOCK
TRANSFER
In this mode, CS is inactive (high) between serial I/O CLOCK transfers, and each transfer can be 11 to 16 clocks
long. The falling edge of CS begins the sequence by removing DATA OUT from the high-impedance state. The
rising edge of CS ends the sequence by returning DATA OUT to the high-impedance state within the specified
delay time. Also, the rising edge of CS disables the I/O CLOCK and ADDRESS terminals within a setup time
plus two falling edges of the internal system clock.

SLAS052G–MARCH 1992–REVISED JANUARY 2006
MODE 4: FAST MODE, CS ACTIVE (LOW) CONTINUOUSLY, 16-CLOCK TRANSFER
In this mode, CS is active (low) between serial I/O CLOCK transfers and each transfer must be exactly 16 clocks
long. After the initial conversion cycle, CS is held active (low) for subsequent conversions; the rising edge of
EOC then begins each sequence by removing DATA OUT from the low logic level, allowing the MSB of the
previous conversion to appear immediately on this output.
SLOW MODES
In a slow mode, the conversion is completed before the serial I/O CLOCK data transfer is completed. A slow
mode requires a minimum 11-clock transfer into I/O CLOCK, and the rising edge of the eleventh clock must
occur before the conversion period is complete; otherwise, the device loses synchronization with the host-serial
interface and CS has to be toggled to initialize the system. The eleventh rising edge of the I/O CLOCK must
occur within 9.5 µs after the tenth I/O clock falling edge.
MODE 5: SLOW MODE, CS INACTIVE (HIGH) BETWEEN CONVERSION CYCLES, 11- to 16-CLOCK
TRANSFER
In this mode, CS is inactive (high) between serial I/O CLOCK transfers and each transfer can be 11 to 16 clocks
long. The falling edge of CS begins the sequence by removing DATA OUT from the high-impedance state. The
rising edge of CS ends the sequence by returning DATA OUT to the high-impedance state within the specified
delay time. Also, the rising edge of CS disables the I/O CLOCK and ADDRESS terminals within a setup time
plus two falling edges of the internal system clock.
MODE 6: SLOW MODE, CS ACTIVE (LOW) CONTINUOUSLY, 16-CLOCK TRANSFER
In this mode, CS is active (low) between serial I/O CLOCK transfers and each transfer must be exactly 16 clocks
long. After the initial conversion cycle, CS is held active (low) for subsequent conversions. The falling edge of
the sixteenth I/O CLOCK then begins each sequence by removing DATA OUT from the low state, allowing the
MSB of the previous conversion to appear immediately at DATA OUT. The device is then ready for the next
16-clock transfer initiated by the serial interface.
ADDRESS BITS
The 4-bit analog channel-select address for the next conversion cycle is presented to the ADDRESS terminal
(MSB first) and is clocked into the address register on the first four leading edges of I/O CLOCK. This address
selects one of 14 inputs (11 analog inputs or three internal test inputs).
ANALOG INPUTS AND TEST MODES
The 11 analog inputs and the three internal test inputs are selected by the 14-channel multiplexer according to
the input address as shown in Tables 2 and 3. The input multiplexer is a break-before-make type to reduce
input-to-input noise injection resulting from channel switching.
Sampling of the analog input starts on the falling edge of the fourth I/O CLOCK, and sampling continues for six
I/O CLOCK periods. The sample is held on the falling edge of the tenth I/O CLOCK. The three test inputs are
applied to the multiplexer, sampled, and converted in the same manner as the external analog inputs.

CONVERTER AND ANALOG INPUT
The CMOS threshold detector in the successive-approximation conversion system determines each bit by
examining the charge on a series of binary-weighted capacitors (see Figure 1). In the first phase of the
conversion process, the analog input is sampled by closing the SC switch and all ST switches simultaneously.
This action charges all the capacitors to the input voltage.
In the next phase of the conversion process, all ST and SC switches are opened and the threshold detector
begins identifying bits by identifying the charge (voltage) on each capacitor relative to the reference (REF-)
voltage. In the switching sequence, ten capacitors are examined separately until all ten bits are identified and
then the charge-convert sequence is repeated. In the first step of the conversion phase, the threshold detector
looks at the first capacitor (weight = 512). Node 512 of this capacitor is switched to the REF+ voltage, and the
equivalent nodes of all the other capacitors on the ladder are switched to REF-. If the voltage at the summing
node is greater than the trip point of the threshold detector (approximately one-half VCC), a 0 bit is placed in the
output register and the 512-weight capacitor is switched to REF-. If the voltage at the summing node is less than
the trip point of the threshold detector, a 1 bit is placed in the register and the 512-weight capacitor remains
connected to REF+ through the remainder of the successive-approximation process. The process is repeated for
the 256-weight capacitor, the 128-weight capacitor, and so forth down the line until all bits are counted.
With each step of the successive-approximation process, the initial charge is redistributed among the capacitors.
The conversion process relies on charge redistribution to count and weigh the bits from MSB to LSB.

CHIP-SELECT OPERATION
The trailing edge of CS starts all modes of operation, and CS can abort a conversion sequence in any mode. A
high-to-low transition on CS within the specified time during an ongoing cycle aborts the cycle, and the device
returns to the initial state (the contents of the output data register remain at the previous conversion result).
Exercise care to prevent CS from being taken low close to completion of conversion because the output data
can be corrupted.
REFERENCE VOLTAGE INPUTS
There are two reference inputs used with the device: REF+ and REF-. These voltage values establish the upper
and lower limits of the analog input to produce a full-scale and zero reading respectively. The values of REF+,
REF-, and the analog input should not exceed the positive supply or be lower than GND consistent with the
specified absolute maximum ratings. The digital output is at full scale when the input signal is equal to or higher
than REF+ and at zero when the input signal is equal to or lower than REF-.

(1) Analog input voltages greater than that applied to REF+ convert as all ones (1111111111), while input voltages less than that applied to
REF- convert as all zeros (0000000000). The device is functional with reference voltages down to 1 V (Vref+ - Vref-); however, the
electrical specifications are no longer applicable.
(2) To minimize errors caused by noise at CS, the internal circuitry waits for a setup time plus two falling edges of the internal system clock
after CS↓ before responding to control input signals. Therefore, no attempt should be made to clock in an address until the minimum CS
setup time has elapsed.
(3) For 11- to 16-bit transfers, after the tenth I/O CLOCK falling edge (≤ 2 V) at least 1 I/O CLOCK rising edge (≥ 2 V) must occur within 9.5
µs.
(4) This is the time required for the clock input signal to fall from VIHmin to VILmax or to rise from VILmax to VIHmin. In the vicinity of normal
room temperature, the devices function with input clock transition time as slow as 1 µs for remote data-acquisition applications where
the sensor and the A/D converter are placed several feet away from the controlling microprocessor.

between 1111111111 and the converted output for full-scale input voltage.
(4) Analog input voltages greater than that applied to REF+ convert as all ones (1111111111), while input voltages less than that applied to
REF- convert as all zeros (0000000000). The device is functional with reference voltages down to 1 V (Vref+-Vref-); however, the
electrical specifications are no longer applicable.

SIMPLIFIED ANALOG INPUT ANALYSIS
Using the equivalent circuit in Figure 17Figure 17, the time required to charge the analog input capacitance from
0 to VS within 1/2 LSB can be derived as follows:
The capacitance charging voltage is given by
−t /R C
t i
c
V = V
(1−e
)
C
S
where
R = R + r
i
t
s

The final voltage to 1/2 LSB is given by
V (1/2 LSB) = V − (V /2048)
C

Equating equation 1 to equation 2 and solving for time tc gives
−t /R C

and
t (1/2 LSB) = R × C × ln(2048)

Therefore, with the values given the time for the analog input signal to settle is
t (1/2 LSB) = (R + 1 kΩ) × 60 pF × ln(2048)

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
