MAX31725
±0.5°C Local Temperature Sensor
Ultra-Accurate Temperature Sensor Offers ±0.5°C (max) Accuracy Over a Wide -40°C to +105°C Range
Description
The MAX31725 temperature sensor 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, 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 2.5V to 3.7V supply voltage range, low 600µA supply current, and a lockup-protected I²C-compatible interface make this sensor ideal for a wide range of applications,
including PCs, electronic test equipment, and office electronics.
It is available in an 8-pin TDFN package and operates over the -55°C to +150°C temperature range.
