General Description

The MAX31725/MAX31726 temperature sensors accurately measure temperature and provide an overtemperature alarm/interrupt/shutdown output. These devices convert the temperature measurements to digital form using a high-resolution, sigma-delta, analog-todigital converter (ADC). Accuracy is Q0.5NC from -40NC to +105NC. Communication is through an I2C-compatible 2-wire serial interface.
