Temp Sensor Digital Serial (2-Wire, I2C) 8-Pin TDFN EP T/R

The MAX31726 temperature sensors accurately measure temperature and provide an over temperature 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 Q0.5NC 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 over temperature shutdown output. The MAX31726 features two address select lines with a total of 16 available addresses and a RESET\ input. The sensors have a 2.5V to 3.7V supply voltage range, low 600FA 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. The device are available in an 8-pin TDFN package and operate over the -55°C to +150°C temperature range.
