GENERAL DESCRIPTION

The TMP35/TMP36/TMP37 are low voltage, precision centigrade temperature sensors. They provide a voltage output that is linearly proportional to the Celsius (centigrade) temperature. The TMP35/ TMP36/TMP37 do 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.

FEATURES

Low voltage operation (2.7 V to 5.5 V)

Calibrated directly in °C

10 mV/°C scale factor (20 mV/°C on TMP37)
