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.
