MAX31875
MAX31875 is Low-Power I2C Temperature Sensor manufactured by Maxim Integrated.
Description
The MAX31875 is a ±1°C-accurate local temperature sensor with I2C/SMBus interface. The bination of tiny package and excellent temperature measurement accuracy makes this product ideal for a variety of equipment. The I2C/SMBus-patible serial interface accepts standard write byte, read byte, send byte, and receive byte mands 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 munication 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.
