GENERAL DESCRIPTION
The TMP03/TMP04 are monolithic temperature detectors that
generate a modulated serial digital output that varies in direct
proportion to the temperature of the device. An onboard sensor
generates a voltage precisely proportional to absolute tempera-
ture 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 is ±1.5°C
(typical) from –25°C to +100°C, with excellent transducer lin-
earity. The digital output of the TMP04 is CMOS/TTL
compatible, and is easily interfaced to the serial inputs of most
popular microprocessors. The open-collector output of the
TMP03 is capable of sinking 5 mA. The TMP03 is best suited
for systems requiring isolated circuits utilizing optocouplers or
isolation transformers.
The TMP03 and TMP04 are specified for operation at supply
voltages from 4.5 V to 7 V. Operating from 5 V, supply current
(unloaded) is less than 1.3 mA.
The TMP03/TMP04 are rated for operation over the –40°C to
+100°C temperature range in the low cost TO-92, SO-8, and
TSSOP-8 surface mount packages. Operation extends to 150°C
with reduced accuracy.

WARNING!
ESD SENSITIVE DEVICE
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 the TMP03 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.

*CAUTION
1
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation at or
above this specification is not implied. Exposure to the above maximum rating
conditions for extended periods may affect device reliability.
2
Digital inputs and outputs are protected, however, permanent damage may occur
on unprotected units from high-energy electrostatic fields. Keep units in conduc-
tive foam or packaging at all times until ready to use. Use proper antistatic
handling procedures.
3
Remove power before inserting or removing units from their sockets.
