Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community TMP401 SBOS371B – AUGUST 2006 – REVISED OCTOBER 2014 TMP401 ±1°C Programmable, Remote and Local, Digital Out Temperature Sensor.

General Description

The TMP401 is a remote temperature sensor monitor with a built-in local temperature sensor.

The remote sensor is capable of monitoring the temperature of any external PN junction.

Typical sense elements include low-cost NPN- or PNP-type transistors and diodes, or accessible thermal diodes integrated within microcontrollers, microprocessors, or fieldprogrammable gate arrays (FPGAs).
