TMP431 Datasheet Temperature Sensor

Manufacturer: Texas Instruments

General Description

The TMP431 and TMP432 are remote temperature sensor monitors with a built-in local temperature sensor.

The remote temperature sensor diodeconnected transistors are typically low-cost, NPN- or PNP-type transistors or diodes that are an integral part of microcontrollers, microprocessors, or FPGAs.

Remote accuracy is ±1°C for multiple device manufacturers, with no calibration needed.
