The SY24697 is a high accuracy digital temperature sensor with an internal 12-bit ADC, and its temperature sensor is highly linear. This device has an accuracy of ±0.5°C, and its resolution can be as low as 0.0625°C. The SY24697 doesn’t require an external component assistance or other external calibration, only a simple calculation formula is needed to obtain the temperature result directly, so this device is a simple and high-precision alternative to thermistors such as NTC/PTC.

The SY24697 supports SMBus and I²C interface, it features SMBus alert function. The SY24697 has four optional communication addresses, and four devices are allowed to connect to the bus at the same time. The supply voltage of this device is 1.62V to 3.6V, and the maximum quiescent current is 7.5µA in the full supply voltage range. The 1.6mm×1.6mm SOT563 package is 68% smaller than the SOT-23.

The SY24697 can operate in a temperature range of -40°C to 125°C. It is an ideal temperature measuring device in the communication, computer, consumer, environmental, industrial and instrumentation applications.
