TMP421 - (TMP421 / TMP422) Remote and Local TEMPERATURE SENSOR

Download the TMP421 datasheet PDF. This datasheet also covers the TMP421_Burr variant, as both devices belong to the same (tmp421 / tmp422) remote and local temperature sensor family and are provided as variant models within a single manufacturer datasheet.

General Description

The TMP421 and TMP422 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 FPGAs.

Key Features

  • SOT23-8.
