Analog Devices / Maxim Integrated MAX31875 Low-Power I2C Temperature Sensor
Analog Devices MAX31875 Low-Power I2C Temperature Sensor features an I2C/SMBus interface and has a ±2 temperature measurement accuracy. The MAX31875 is housed in a tiny package and is ideal for a variety of equipment. The I2C/SMBus-compatible serial interface accepts standard write byte, read byte, send byte, and receive byte commands to read the temperature data and configure the behavior of the sensor.
Bus timeout resets the interface if the clock is low for more than 30ms (nominal). PEC helps to avoid communication errors when used with a master that supports this feature. The Analog Devices MAX31875 is available in a 4-bump, wafer-level package (WLP) and operates over the -20°C to +150°C temperature range.
