TMP37FS

低电压温度传感器 Low Voltage Temperature Sensors

PRODUCT DESCRIPTION

The TMP35, TMP36, and TMP37 are low voltage, precision

centigrade temperature sensors. They provide a voltage output

that is linearly proportional to the Celsius Centigrade tem

perature. 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.
