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 ?.5癈
(typical) from 25癈 to +100癈, 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 5mA. 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 1.3mA.
The TMP03/TMP04 are rated for operation over the 40癈 to
+100癈 temperature range in the low cost TO-92, SO-8, and
TSSOP-8 surface mount packages. Operation extends to 150癈
with reduced accuracy.
