TMP03FS [Rochester]

The TMP03/TMP04 are monolithic temperature detectors with an onboard sensor that generates a voltage precisely proportional to absolute temperature, 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 clock drift errors. Overall accuracy is ±1.5°C (typical) from –25°C to +100°C, with excellent transducer linearity. The digital output of the TMP04 is CMOS/TTL compatible, and the open-collector output of the TMP03 is capable of sinking 5mA. They operate from 4.5V to 7V supply, with supply current less than 1.3mA at 5V. Rated for operation over –40°C to +100°C in low-cost TO-92, SO-8, and TSSOP-8 packages, with operation extending to 150°C with reduced accuracy.
