MAX31725MTA+T

MAX31725MTA+T is a temperature sensor that accurately measures temperature and provides an overtemperature alarm/interrupt/shutdown output. This device converts the temperature measurements to digital form using a high-resolution, sigma-delta, analogue-to-digital converter (ADC). The I²C serial interface accepts standard write byte, read byte, send byte, and receive byte commands to read the temperature data and configure the behaviour of the open-drain over temperature shutdown output. It features three address select lines with a total of 32 available addresses. This sensor has 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.
