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-to-digital converter (ADC). Accuracy is ±0.5°C from -40°C to +105°C. Communication is through an I2C-compatible 2-wire serial interface.
The I2C 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 open-drain overtemperature shutdown output.
The MAX31725 features three address select lines with a total of 32 available addresses. The MAX31726 features two address select lines with a total of 16 available addresses and an active-low RESET input. The sensors have a 2.5V to 3.7V supply voltage range, low 600µA supply current, and a lockup-protected I2C-compatible interface that make them ideal for a wide range of applications, including PCs, electronic test equipment, and office electronics.
Both devices are available in an 8-pin TDFN package and operate over the -55°C to +150°C temperature range.
