Overview
The TMP36FS, produced by Analog Devices Inc., is a low voltage, precision centigrade temperature sensor. It provides a voltage output that is linearly proportional to the Celsius (centigrade) temperature. This sensor does not require any external calibration and offers typical accuracies of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range. The TMP36FS is designed for single-supply operation from 2.7 V to 5.5 V and features a low quiescent current of less than 50 μA, resulting in minimal self-heating of less than 0.1°C in still air.
