Overview
The TMP36GS, produced by Analog Devices Inc., is a low-voltage, precision centigrade temperature sensor. It is part of the TMP35/TMP36/TMP37 family, which provides a voltage output that is linearly proportional to the Celsius temperature. The TMP36GS is specifically designed to operate over a temperature range of −40°C to +125°C and can function with a single supply voltage from 2.7 V to 5.5 V. This sensor is known for its high accuracy, low self-heating, and ease of interfacing with temperature control circuitry and analog-to-digital converters (ADCs).
