GENERAL DESCRIPTION
The TMP05/TMP06 are monolithic temperature sensors that
generate a modulated serial digital output (PWM), which varies
in direct proportion to the temperature of the devices. The high
period (TH) of the PWM remains static over all temperatures,
while the low period (TL) varies. The B Grade version offers a
higher temperature accuracy of ±±1° from 01° to 701°, with
excellent transducer linearity. The digital output of the TMP05/
TMP06 is °MOS/TTL compatible, and is easily interfaced to
the serial inputs of most popular microprocessors. The flexible
open-drain output of the TMP06 is capable of sinking 3 mA.
The °ONV/IN input pin is used to determine the rate with
which the TMP05/TMP06 measure temperature in
continuously converting mode and one shot mode. In
daisy-chain mode, the °ONV/IN pin operates as the input
to the daisy chain.
PRODUCT HIGHLIGHTS
±. The TMP05/TMP06 have an on-chip temperature sensor
that allows an accurate measurement of the ambient
temperature. The measurable temperature range is –401°
to +±501°.
The TMP05/TMP06 are specified for operation at supply
voltages from 3 V to 5.5 V. Operating at 3.3 V, the supply current
(unloaded) is typically 230 µA. The TMP05/TMP06 are rated
for operation over the –401° to +±501° temperature range.
They are packaged in low cost, low area S°-70 and SOT-23
packages.
2. Supply voltage of 3 V to 5.5 V.
3. Space-saving 5-lead SOT-23 and S°-70 packages.
4. Temperature accuracy of ±0.51°.
5. 0.021° temperature resolution.
The TMP05/TMP06 have three modes of operation: continu-
ously converting mode, daisy-chain mode, and one shot mode.
A three-state FUN° input determines the mode in which the
TMP05/TMP06 operate.
6. The TMP05/TMP06 feature a one shot mode that reduces
the power consumption to 2.57 µW at one sample per
second.

2 SOT-23 values relate to the package being used on a 2-layer PCB and SC-70
values relate to the package being used on a 4-layer PCB. See Figure 4 for a
plot of maximum power dissipation versus ambient temperature (TA).
3 TA = ambient temperature.
4 Junction-to-case resistance is applicable to components featuring a
preferential flow direction, for example, components mounted on a heat
sink. Junction-to-ambient resistance is more useful for air-cooled PCB
mounted components.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

The modulated output of the comparator is encoded using a
circuit technique that results in a serial digital signal with a
mark-space ratio format. This format is easily decoded by any
microprocessor into either 1° or 1F values, and is readily
transmitted or modulated over a single wire. More importantly,
this encoding method neatly avoids major error sources
common to other modulation techniques, because it is clock-
independent.
CIRCUIT INFORMATION
The TMP05/TMP06 are monolithic temperature sensors that
generate a modulated serial digital output that varies in direct
proportion with the temperature of the device. An on-board
sensor generates a voltage precisely proportional to absolute
temperature, which is compared to an internal voltage reference
and input to a precision digital modulator. The ratiometric
encoding format of the serial digital output is independent of
the clock drift errors common to most serial modulation
techniques such as voltage-to-frequency converters. Overall
accuracy for the A Grade is ±21° from 01° to 701°, with
excellent transducer linearity. B Grade accuracy is ±±1° from
01° to 701°. The digital output of the TMP05 is °MOS/TTL
compatible, and is easily interfaced to the serial inputs of most
popular microprocessors. The open-drain output of the TMP06
is capable of sinking 3 mA.
FUNCTIONAL DESCRIPTION
The output of the TMP05/TMP06 is a square wave with a
typical period of ±±6 ms at 251° (°ONV/IN pin is left floating).
The high period, TH, is constant, while the low period, TL, varies
with measured temperature. The output format for the nominal
conversion rate is readily decoded by the user as follows:
Temperature (1°) = 42± − (75± × (TH/TL))
(±)
The on-board temperature sensor has excellent accuracy and
linearity over the entire rated temperature range without
correction or calibration by the user.

The sensor output is digitized by a first-order ∑-∆ modulator,
also known as the charge balance type analog-to-digital
converter. This type of converter utilizes time-domain over-
sampling and a high accuracy comparator to deliver ±2 bits of
effective accuracy in an extremely compact circuit.
Figure 25. TMP05/TMP06 Output Format
The time periods TH (high period) and TL (low period) are
values easily read by a microprocessor timer/counter port, with
the above calculations performed in software. Because both
periods are obtained consecutively using the same clock,
performing the division indicated in the previous formula
results in a ratiometric value that is independent of the exact
frequency or drift of either the originating clock of the
TMP05/TMP06 or the user’s counting clock.
CONVERTER DETAILS
The ∑-∆ modulator consists of an input sampler, a summing
network, an integrator, a comparator, and a ±-bit DA°. Similar
to the voltage-to-frequency converter, this architecture creates,
in effect, a negative feedback loop whose intent is to minimize
the integrator output by changing the duty cycle of the
comparator output in response to input voltage changes. The
comparator samples the output of the integrator at a much
higher rate than the input sampling frequency, which is called
oversampling. Oversampling spreads the quantization noise
over a much wider band than that of the input signal, improving
overall noise performance and increasing accuracy.
OPERATING MODES
The user can program the TMP05/TMP06 to operate in three
different modes by configuring the FUN° pin on power-up as
either high, low, or floating.

frequency at which this square wave is output is determined by
the state of the °ONV/IN pin on power-up. Any change to the
state of the °ONV/IN pin after power-up is not reflected in the

Figure 26. TMP05/TMP06 One Shot OUT Pin Signal
One Shot Mode
In one shot mode, the TMP05/TMP06 output one square wave
representing temperature when requested by the microcon-
troller. The microcontroller pulls the OUT pin low and then
releases it to indicate to the TMP05/TMP06 that an output is
required. The temperature measurement is output when the
OUT line is released by the microcontroller (see Figure 26).

In the TMP05 one shot mode only, an internal resistor is
switched in series with the pull-up MOSFET. The TMP05 OUT
pin has a push-pull output configuration (see Figure 27), and,
therefore, needs a series resistor to limit the current drawn on
this pin when the user pulls it low to start a temperature
conversion. This series resistance prevents any short circuit
from VDD to GND, and, therefore, protects the TMP05 from
short-circuit damage.
The TMP05 (push-pull output) advantage when using the high
state conversion rate (double high/quarter low) is lower power
consumption. However, the trade-off is loss of resolution on the
low time. Depending on the state of the °ONV/IN pin, two
different temperature equations must be used.

sion rates is

A second microcontroller line is needed to generate the conver-
sion START pulse on the °ONV/IN pin. The pulse width of the
START pulse should be less than 25 µs. The START pulse on the
°ONV/IN pin lets the first TMP05/TMP06 part know that it
should start a conversion and output its own temperature now.
Once the part has output its own temperature, it then outputs a
START pulse for the next part on the daisy-chain link. The
pulse width of the START pulse from each TMP05/TMP06 part
is typically ±7 µs.

Setting the FUN° pin to a high state allows multiple TMP05/
TMP06s to be connected together and, therefore, allows one
input line of the microcontroller to be the sole receiver of all
temperature measurements. In this mode, the °ONV/IN pin
operates as the input of the daisy chain, and conversions take
place at the nominal conversion rate, that is, TH/TL = 40 ms/

Figure 31. Daisy-Chain Signal at Input to the Microcontroller
Before the START pulse reaches a TMP05/TMP06 part in the
daisy chain, the device acts as a buffer for the previous tempera-
ture measurement signals. Each part monitors the PWM signal
for the START pulse from the previous part. Once the part
detects the START pulse, it initiates a conversion and inserts the
result at the end of the daisy-chain PWM signal. It then inserts a
START pulse for the next part in the link. The final signal input
to the microcontroller should look like Figure 3±. The input
signal on Pin 2 (IN) of the first daisy-chain device must remain
low until the last device has output it’s START pulse.
An internal resistor is connected in series with the pull-up
MOSFET when the TMP05 is operating in one shot mode.
V+
OUT
If the input on Pin 2 (IN) goes high and remains high, the
TMP05/TMP06 part powers down between 0.3 s and ±.2 s later.
The part, therefore, requires another START pulse to generate
another temperature measurement. Note that, to reduce power
dissipation through the part, it is recommended to keep Pin 2
(IN) at a high state when the part is not converting. If the IN
pin is at 0 V, then the OUT pin is at 0 V (because it is acting as a
buffer when not converting), and drawing current through
either the pull-up MOSFET (TMP05) or the pull-up resistor
(TMP06).
TMP05
Figure 32. TMP05 Digital Output Structure
TMP06 OUTPUT
The TMP06 has an open-drain output. Because the output
source current is set by the pull-up resistor, output capacitance
should be minimized in TMP06 applications. Otherwise,
unequal rise and fall times skew the pulse width and introduce
measurement errors.
TMP0ꢀ OUTPUT
The TMP05 has a push-pull °MOS output (Figure 32) and
provides rail-to-rail output drive for logic interfaces. The rise
and fall times of the TMP05 output are closely matched, so that
errors caused by capacitive loading are minimized. If load
capacitance is large (for example, when driving a long cable), an
external buffer might improve accuracy.

THERMAL RESPONSE TIME
SUPPLY DECOUPLING
The time required for a temperature sensor to settle to a
specified accuracy is a function of the thermal mass of the
sensor and the thermal conductivity between the sensor and the
object being sensed. Thermal mass is often considered
equivalent to capacitance. Thermal conductivity is commonly
specified using the symbol Q, and can be thought of as thermal
resistance. It is commonly specified in units of degrees per watt
of power transferred across the thermal joint. Thus, the time
required for the TMP05/TMP06 to settle to the desired
accuracy is dependent on the package selected, the thermal
contact established in that particular application, and the
equivalent power of the heat source. In most applications, the
settling time is probably best determined empirically.
The TMP05/TMP06 should be decoupled with a 0.± µF ceramic
capacitor between VDD and GND. This is particularly important,
if the TMP05/TMP06 are mounted remotely from the power
supply. Precision analog products such as the TMP05/TMP06
require a well filtered power source. Because the TMP05/
TMP06 operate from a single supply, it might seem convenient
to simply tap into the digital logic power supply. Unfortunately,
the logic supply is often a switch-mode design, which generates
noise in the 20 kHz to ± MHz range. In addition, fast logic gates
can generate glitches hundreds of mV in amplitude due to
wiring resistance and inductance.
If possible, the TMP05/TMP06 should be powered directly
from the system power supply. This arrangement, shown in
Figure 34, isolates the analog section from the logic switching
transients. Even if a separate power supply trace is not available,
however, generous supply bypassing reduces supply-line-
induced errors. Local supply bypassing consisting of a 0.± µF
ceramic capacitor is recommended.
SELF-HEATING EFFECTS
The temperature measurement accuracy of the TMP05/TMP06
might be degraded in some applications due to self-heating.
Errors introduced are from the quiescent dissipation and power
dissipated when converting, that is, during TL. The magnitude of
these temperature errors is dependent on the thermal

conductivity of the TMP05/TMP06 package, the mounting
technique, and the effects of airflow. Static dissipation in the
TMP05/TMP06 is typically ±0 W operating at 3.3 V with no
load. In the 5-lead S°-70 package mounted in free air, this
accounts for a temperature increase due to self-heating of

In addition, power is dissipated by the digital output, which is
capable of sinking 800 µA continuously (TMP05). Under an 800
µA load, the output may dissipate
TEMPERATURE MONITORING
The TMP05/TMP06 are ideal for monitoring the thermal
environment within electronic equipment. For example, the
surface-mounted package accurately reflects the exact thermal
conditions that affect nearby integrated circuits.
P
DISS = (0.4 V)(0.8 mA)((TL)/TH + TL))
(6)
For example, with TL = 80 ms and TH = 40 ms, the power
dissipation due to the digital output is approximately 0.2± mW.
In a free-standing S°-70 package, this accounts for a tempera-
ture increase due to self-heating of
The TMP05/TMP06 measure and convert the temperature at
the surface of their own semiconductor chip. When the TMP05/
TMP06 are used to measure the temperature of a nearby heat
source, the thermal impedance between the heat source and the
TMP05/TMP06 must be considered. Often, a thermocouple or
other temperature sensor is used to measure the temperature of
the source, while the TMP05/TMP06 temperature is monitored
by measuring TH and TL. Once the thermal impedance is deter-
mined, the temperature of the heat source can be inferred from
the TMP05/TMP06 output.
ꢀT = PDISS × θJA = 0.2± mW × 2±±.41°/W = 0.0441° (7)
This temperature increase adds directly to that from the
quiescent dissipation and affects the accuracy of the
TMP05/TMP06 relative to the true ambient temperature.
It is recommended that current dissipated through the device be
kept to a minimum, because it has a proportional effect on the
temperature error.
One example of using the TMP05/TMP06’s unique properties is
in monitoring a high power dissipation microprocessor. The
TMP05/TMP06 part, in a surface-mounted package, is mounted
directly beneath the microprocessor’s pin grid array (PGA)
package. In a typical application, the TMP05/TMP06’s output

would be connected to an ASI°, where the pulse width would
be measured. The TMP05/TMP06 pulse output provides a
significant advantage in this application, because it produces a
linear temperature output while needing only one I/O pin and
without requiring an A/D converter.
