Abstract
A sensing system comprising a sensor for generating an analog electrical signal indicative of a sensed physical property and an A/D converter for converting the analog electrical signal into a digital electrical signal. A control circuit connected to the A/D converter is configured to receive the digital electrical signal and to perform a plurality of sensing system operations including determining a measurement value of the physical property as a function of said received digital electrical signal. A slew rate detection circuit connected to the sensor is configured to detect when the analog electrical signal indicates a slew rate that exceeds a threshold value, and to generate an interrupt electrical signal when the slew rate is detected as exceeding the threshold value. The control circuit determines a measurement value of the physical property in response to receiving the interrupt signal.
