The SY24697 is a high accuracy linear digital temperature sensor with an internal 12-bit ADC. This device has an accuracy of ±0.5°C with a resolution as low as 0.0625°C. The SY24697 doesn’t require any external component or external calibration. Only a simple formula is needed to calculate the temperature result directly. This device is a simple and high-precision alternative to thermistors, such as NTC/PTC.
The SY24697 supports SMBus and I2C interfaces. It features SMBus alert function. Using a single pin, one of the four peripheral addresses can be selected. Up to four devices are allowed to be connected to the bus at the same time. The supply voltage of this device is 1.62V to 3.6V. The maximum quiescent current is 7.5µA across the full supply voltage range. Its 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 communication, computer, consumer, environmental, industrial and instrumentation applications.
