In summary, the MAX31875 is a ±2°C-accurate local temperature sensor with I²C/SMBus interface. The combination of tiny package and excellent temperature measurement accuracy makes 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 30 ms (nominal). PEC (Packet Error Checking) 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 -20°C to +150°C temperature range.
