TMP36GT9Z

板上安装温度传感器 Low VTG Prec Vout 2.7-5.5V

Low Voltage Temperature Sensors

GENERAL DESCRIPTION TMP36GT9Z

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.

The low output impedance of the TMP35/TMP36/TMP37 and

its linear output and precise calibration simplify interfacing to

temperature control circuitry and ADCs. All three devices are

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. In addition, a

shutdown function is provided to cut the supply current to less

than 0.5 μA.
