SP-TMP36

Overview

Introduction

SP-TMP36 is a three terminal probe based on the low voltage, precision centigrade temperature sensor TMP-36 (Analog Devices). It provides a voltage output that is linearly proportional to the Celsius (centigrade) temperature with a scale factor of 10 mV/°C. SP-TMP36 does not require any external calibration to provide typical accuracies of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range. It is intended for single-supply operation from 2.7 V to 5.5 V maximum. The supply current runs well below 50 μA, providing very low self-heating, less than 0.1°C in still air.

Features

Highly linear output (±0.5°C typ).
Wide temperature range: -40°C to +125°C.
Calibrated directly in °C.
Ultra low power: less than 50 μA quiescent current.
Waterproof standard version.
