Abstract
A slew rate detection circuit connected to a sensor detects when an analog electrical signal from the sensor indicates a slew rate that exceeds a threshold value, and generates an interrupt electrical signal when the slew rate is detected as exceeding the threshold value. A control circuit determines a measurement value of the physical property in response to receiving the interrupt signal. The control circuit is connected to an A/D converter, which converts the analog electrical signal into a digital electrical signal, and performs a plurality of sensing system operations including determining the measurement value of the physical property as a function of the digital electrical signal.
