The TMP03/TMP04 are monolithic temperature detectors that generate a modulated serial digital output that varies in direct
TMP03/TMP04
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
D V+ OUT GND
input to a precision digital modulator. The ratiometric encoding
BOTTOM VIEW (Not to Scale)
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
SO-8
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

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. (continued on page 4)
