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. (continued on page 4) Rev. B Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
