TMP421 Datasheet (Texas Instruments) - Remote and Local TEMPERATURE SENSOR

TMP421, Remote and Local TEMPERATURE SENSOR

The TMP421, TMP422, and TMP423 are remote temperature sensor monitors with a built-in local temperature sensor.

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