Analog Devices / Maxim Integrated MAX31828 Low-Power Temperature Switches

Analog Devices MAX31828 Low-Power Temperature Switches provide ±1°C accuracy from -40°C to +125°C (12 bits). These switches have an I2C/SMBus interface and are housed in a small 6-bump wafer-level package. The devices have high accuracy and are ideal for many applications. The Analog Devices MAX31828 is used as a temperature switch with preconfigured thresholds and/or as a temperature sensor with an I2C interface.
