The MAX31875 is a ±1°C-accurate local temperature sensor with I²C/SMBus interface. The combination of tinypackage and excellent temperature measurement accuracymakes this product 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 MAX31875 is available in a 4-bump, wafer-level package (WLP) and operates over the -50°C to +150°C temperature range.
