Description
tiny SC70 package
GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The AD5602/AD5612/AD5622, members of the nanoDAC
family, are single 8-, 10-, 12-bit buffered voltage-out DACs that
operate from a single 2.7 V to 5.5 V supply, consuming <100 μA
at 5 V. These DACs come in tiny SC70 packages. Each DAC
contains an on-chip precision output amplifier that allows rail-
to-rail output swing to be achieved.
1. Available in a 6-lead SC70 package.
2. Maximum 100 μA power consumption, single-supply
operation. These parts operate from a single 2.7 V to 5.5 V
supply, typically consuming 0.2 mW at 3 V and 0.4 mW at
5 V, making them ideal for battery-powered applications.
3. The on-chip output buffer amplifier allows the output of
the DAC to swing rail-to-rail with a typical slew rate of
0.5 V/μs.
The AD5602/AD5612/AD5622 use a 2-wire I2C-compatible
serial interface that operates in standard (100 kHz), fast
(400 kHz), and high speed (3.4 MHz) modes.
4. Reference derived from the power supply.
5. Standard, fast, and high speed mode I2C interface.
6. Designed for very low power consumption.
The references for AD5602/AD5612/AD5622 are derived from
the power supply inputs to give the widest dynamic output range.
Each part incorporates a power-on reset circuit that ensures the
DAC output powers up to 0 V and remains there until a valid
write takes place to the device. The parts contain a power-down
feature that reduces the current consumption of the devices to
<150 nA at 3 V and provides software-selectable output loads
while in power-down mode. The parts are put into power-down
mode over the serial interface. The low power consumption of
the AD5602/AD5612/AD5622 in normal operation makes them
ideally suited for use in portable battery-operated equipment. The
typical power consumption is 0.4 mW at 5 V.
7. Power-down capability. When powered down, the DAC
typically consumes <150 nA at 3 V.
8. Power-on reset and brownout detection.

1 See Figure 2. High speed mode timing specification applies to the AD5602-1/AD5612-1/AD5622-1 only. Standard and fast mode timing specifications apply to the
AD5602-1/AD5612-1/AD5622-1 and AD5602-2/AD5612-2/AD5622-2.
2 CB refers to the capacitance on the bus line.
3 The SDA and SCL timing is measured with the input filters enabled. Switching off the input filters improves the transfer rate but has a negative effect on EMC behavior
of the part.
4 Input filtering on the SCL and SDA inputs suppress noise spikes that are less than 50 ns for fast mode or 10 ns for high speed mode.

TERMINOLOGY
Relative Accuracy
Gain Error
For the DAC, relative accuracy or integral nonlinearity (INL) is
a measure of the maximum deviation, in LSBs, from a straight
line passing through the endpoints of the DAC transfer
function. A typical INL vs. code plot can be seen in Figure 4.
Gain error is a measure of the span error of the DAC. It is the
deviation in slope of the DAC transfer characteristic from ideal
expressed as a percent of the full-scale range.
Total Unadjusted Error (TUE)
Differential Nonlinearity (DNL)
Total unadjusted error is a measure of the output error taking
all the various errors into account. A typical TUE vs. code plot
can be seen in Figure 10.
Differential nonlinearity is the difference between the measured
change and the ideal 1 LSB change between any two adjacent
codes. A specified differential nonlinearity of 1 LSB maximum
ensures monotonicity. This DAC is guaranteed monotonic by
design. A typical DNL vs. code plot can be seen in Figure 5.
Zero Code Error Drift
Zero code error drift is a measure of the change in zero code
error with a change in temperature. It is expressed in μV/°C.
Zero Code Error
Gain Error Drift
Zero-code error is due to a combination of the offset errors in
the DAC and output amplifier; it is a measure of the output
error when zero code (0x0000) is loaded to the DAC register.
Ideally, the output should be 0 V. The zero-code error is always
positive in the AD5602/AD5612/AD5622 because the output of
the DAC cannot go below 0 V. Zero-code error is expressed in
mV. A plot of zero-code error vs. temperature can be seen in
Figure 17.
Gain error drift is a measure of the change in gain error with
changes in temperature. It is expressed in (ppm of full-scale
range)/°C.
Digital-to-Analog Glitch Impulse
Digital-to-analog glitch impulse is the impulse injected into the
analog output when the input code in the DAC register changes
state. It is normally specified as the area of the glitch in nV-s and
is measured when the digital input code is changed by 1 LSB at
the major carry transition (0x7FFF to 0x8000) (see Figure 32).
Full-Scale Error
Full-scale error is a measure of the output error when full-scale
code (0xFFFF) is loaded to the DAC register; it is expressed in
Digital Feedthrough
percent of full-scale range. Ideally, the output should be VDD
–
Digital feedthrough is a measure of the impulse injected into
the analog output of the DAC from the digital inputs of the DAC,
but is measured when the DAC output is not updated. It is
specified in nV-s and measured with a full-scale code change on
the data bus, that is, from all 0s to all 1s, and vice versa
(see Figure 33).

The AD5602/AD5612/AD5622 DACs are fabricated on a

where:
The output buffer amplifier is capable of generating rail-to-rail
voltages on its output, giving an output range of 0 V to VDD. It is
capable of driving a load of 2 kΩ in parallel with 1000 pF to
GND. The source and sink capabilities of the output amplifier
can be seen in Figure 26. The slew rate is 0.5 V/μs with a half-
scale settling time of 5 μs with the output unloaded.
D is the decimal equivalent of the binary code that is loaded
to the DAC register; it can range from 0 to 255 (AD5602),
0 to 1023 (AD5612), or 0 to 4095 (AD5622).
n is the bit resolution of the DAC.
RESISTOR STRING
The resistor string structure is shown in Figure 37. It is simply a
string of resistors, each of value R. The code loaded to the DAC
register determines at which node on the string the voltage is
tapped off to be fed into the output amplifier. The voltage is
tapped off by closing one of the switches connecting the string
to the amplifier. Because it is a string of resistors, it is
guaranteed monotonic.

AD5602/AD5612/AD5622
SERIAL INTERFACE
The AD5602/AD5612/AD5622 have 2-wire I2C-compatible
serial interfaces (refer to I2C-Bus Specification, Version 2.1,
January 2000, available from Philips Semiconductor). The
AD5602/AD5612/AD5622 can be connected to an I2C bus as a
slave device, under the control of a master device. See Figure 2
for a timing diagram of a typical write sequence.
3. When all data bits have been read or written, a stop
condition is established. In write mode, the master pulls
the SDA line high during the 10th clock pulse to establish a
stop condition. In read mode, the master issues a no
acknowledge for the ninth clock pulse (that is, the SDA line
remains high). The master then brings the SDA line low
before the 10th clock pulse, and then high during the 10th
clock pulse to establish a stop condition.
The AD5602/AD5612/AD5622 support standard (100 kHz),
fast (400 kHz), and high speed (3.4 MHz) data transfer modes.
Support is not provided for 10-bit addressing and general call
addressing.

The AD5602/AD5612/AD5622 each have a 7-bit slave address.
The five MSBs are 00011 and the two LSBs are determined by
the state of the ADDR pin. The facility to make hardwired
changes to ADDR allows the user to incorporate up to three of
these devices on one bus as outlined in Table 6.
NC (No Connection)
INPUT REGISTER
The input register is 16 bits wide. Figure 38, Figure 39, and
Figure 40 illustrate the contents of the input register for each
part. Data is loaded into the device as a 16-bit word under the
control of a serial clock input, SCL. The timing diagram for this
operation is shown in Figure 2. The 16-bit word consists of four
control bits followed by 8, 10, or 12 bits of data, depending on
the device type. MSB (DB15) is loaded first. The first two bits
are reserved bits that must be set to zero, the next two bits are
control bits that select the mode of operation of the device
(normal mode or any one of three power-down modes). See the
Power-Down Modes section for a complete description. The
remaining bits are left-justified DAC data bits, starting with the
MSB and ending with the LSB.
The 2-wire serial bus protocol operates as follows:
1. The master initiates data transfer by establishing a start
condition, which is when a high-to-low transition on the
SDA line occurs while SCL is high. The following byte is
the address byte, which consists of the 7-bit slave address.
The slave address corresponding to the transmitted address
responds by pulling SDA low during the ninth clock pulse
(this is termed the acknowledge bit). At this stage, all other
devices on the bus remain idle while the selected device
waits for data to be written to, or read from, its shift register.
2. Data is transmitted over the serial bus in sequences of nine
clock pulses (eight data bits followed by an acknowledge
bit). The transitions on the SDA line must occur during the
low period of SCL and remain stable during the high
period of SCL.

POWER-ON RESET
When both bits are set to 0, the part works normally with its
usual power consumption of 100 μA maximum at 5 V. However,
for the three power-down modes, the supply current falls to
<150 nA (at 3 V). Not only does the supply current fall, but the
output stage is internally switched from the output of the
amplifier to a resistor network of known values. This gives the
advantage of knowing the output impedance of the part while
the part is in power-down mode. There are three different
options. The output is connected internally to GND through a
1 kΩ resistor, a 100 kΩ resistor, or it is left open-circuited
(three-state). Figure 41 shows the output stage.
The AD5602/AD5612/AD5622 each contain a power-on reset
circuit that controls the output voltage during power-up. The
DAC register is filled with zeros and the output voltage is 0 V
where it remains until a valid write sequence is made to the
DAC. This is useful in applications where it is important to
know the state of the DAC output while it is in the process of
powering up.
POWER-DOWN MODES
The AD5602/AD5612/AD5622 each contain four separate
modes of operation. These modes are software-programmable
by setting Bit PD1 and Bit PD0 in the control register. Table 7
shows how the state of the bits corresponds to the mode of
operation of the device.

The bias generator, output amplifier, resistor string, and other
associated linear circuitry are all shut down when the power-
down mode is activated. However, the contents of the DAC
register are unaffected when in power-down. The time to exit
power-down is typically 14 μs for VDD = 5 V and 17 μs for VDD
3 V (see Figure 28).

Two bytes of data are then written to the DAC, the most
significant byte followed by the least significant byte as shown in
Figure 39; both of these data bytes are acknowledged by the
AD5602/AD5612/AD5622. A stop condition follows. The write
operations for the three DACs are shown in Figure 42, Figure 43,
and Figure 44.
WRITE OPERATION
When writing to the AD5602/AD5612/AD5622, the user must
begin with a start command followed by an address byte (R/

repeated start followed by the device address. The selected
device then acknowledges its address. All devices continue to
operate in high speed mode until the master issues a stop
condition. When the stop condition is issued, the devices return

HIGH SPEED MODE
High speed mode communication commences after the master
addresses all devices connected to the bus with the Master
Code 00001XXX to indicate that a high speed mode transfer is
to begin. No device connected to the bus is permitted to

APPLICATIONS
CHOOSING A REFERENCE AS POWER SUPPLY
With VDD = 5 V, R1 = R2 = 10 kΩ
The AD5602/AD5612/AD5622 come in tiny SC70 packages
with less than 100 μA supply current, thereby making the
choice of reference dependent upon the application
requirement. For space-saving applications, the ADR425 is
available in an SC70 package with excellent drift at 3ppm/°C. It
also provides very good noise performance at 3.4 μV p-p in the
0.1 Hz to 10 Hz range.

this case. This requires 15 μA of quiescent current and can
therefore drive multiple DACs in the one system, if required.

POWER SUPPLY BYPASSING AND GROUNDING
When accuracy is important in a circuit, it is helpful to carefully
consider the power supply and ground return layout on the
board. The printed circuit board containing the AD5602/
AD5612/AD5622 should have separate analog and digital
sections, each having its own area of the board. If the AD5602,
AD5612, or AD5622 is in a system where other devices require
an AGND to DGND connection, the connection should be
made at one point only. This ground point should be as close as
possible to the AD5602/AD5612/AD5622.

The power supply to the AD5602/AD5612/AD5622 should be
bypassed with 10 μF and 0.1 μF capacitors. The capacitors
should be physically as close as possible to the device with the
0.1 μF capacitor ideally right up against the device. The 10 μF
capacitors are the tantalum bead type. It is important that the
0.1 μF capacitor has low effective series resistance (ESR) and
effective series inductance (ESI), such as common ceramic
types. This 0.1 μF capacitor provides a low impedance path to
ground for high frequencies caused by transient currents due to
internal logic switching.

BIPOLAR OPERATION
The AD5602/AD5612/AD5622 have been designed for single-
supply operation, but a bipolar output range is also possible
using the circuit in Figure 50. The circuit in Figure 50 gives an
output voltage range of 5 V. Rail-to-rail operation at the
amplifier output is achievable using an AD820 or an OP295 as
the output amplifier.
The power supply line should have as large a trace as possible to
provide a low impedance path and reduce glitch effects on the
supply line. Clocks and other fast switching digital signals
should be shielded from other parts of the board by digital
ground. Avoid crossover of digital and analog signals if possible.
When traces cross on opposite sides of the board, ensure that
they run at right angles to each other to reduce feedthrough
effects through the board. The best board layout technique is
the microstrip technique where the component side of the
board is dedicated to the ground plane only and the signal
traces are placed on the solder side. However, the microstrip
technique is not always possible with a 2-layer board.
The output voltage for any input code can be calculated as
