Digital Thermometer and Thermostat; Device Temperature Sensor MAX31723

The MAX31723 provides device temperature sensing and it may be used for thermometers and thermostats. The MAX31723 is compatible with SPi, 3-wire software code. The MAX31723 has an accuracy of ±0.5°C and the MAX31722 has an accuracy of ±2°C.


The MAX31723 device temperature sensor is suitable for digital thermostats and thermometers. MAX31723 suopports SPI or 3-wire communications.. Temperature limits may be stored in NVRAM so that the TOUT_N pin can be triggered when the limits are exceeded while in the comparator mode. This device powers up in the standby state.

The Max31723 temperature range is -55°C to +125°C.

Typically applications are for temperature sensitive systems, hardware temperature monitoring.
