TMP75

1.8V Digital Temperature Sensor with I²C Interface and Alarm Function

Features

Description

The TMP75 is a fully integrated digital temperature

•

Low-voltage alternative to the TMP75AIDR and

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.

TMP75AIDGKR

•

Operating temperature range : - 55°C ~ +125°C

Temperature accuracy : ±0.5°C (0°C ~ +70°C)

Supply voltage range : 1.4V ~ 5.5V

Low quiescent current :

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.

Normal mode : 15μA (typ)

Shutdown mode : 1μA (typ)

•

Resolution : 12-bits (0.0625°C)

Digital Output : I²C

The TMP75 has been precisely calibrated at the

factory, and the user does not need to perform any

additional processing on the temperature output.
