Working Principles

The TMP512AID utilizes a built-in temperature sensor to measure the ambient temperature. It converts the analog temperature reading into a digital value, which is then transmitted through the I2C/SMBus interface. The resolution of the output can be configured to trade-off between accuracy and speed. The interrupt output can be used to trigger an event when the temperature exceeds a certain threshold.
