TMP75传感器变送器的温度传感器-模拟数字输出规格书PDF中文资料

Description

The TMP75 is a fully integrated digital temperature

sensor that can work at low voltage (1.8V) and is fully

pin and register compatible with NCT75 and ADT75.

The TMP75 has a ±1°C accuracy over the operating

temperature range. The on-chip 12-bit analog-to-digital

converter (ADC) provides a temperature resolution of

0.0625°C.

The TMP75 supports up to 8 devices address and

provides an over-temperature alarm function. Based on

programmable upper and lower temperature limits and

an ALERT pin, the TMP75 can be used as a thermostat

or an over-temperature alarm.

The TMP75 has been precisely calibrated at the

factory, and the user does not need to perform any

additional processing on the temperature output.
