Abstract
A sensor integrated circuit can include sensors with differing levels of sensitivity, a first processing channel that responds to a first analog signal generated by a first sensor to generate a first processed signal, and a second processing channel that responds to a second analog signal generated by the second sensor to generate a second processed signal. Where the first sensor can include a pressure or optical sensing element, and the second sensor can include a pressure or optical sensing element. A checker circuit uses the processed signals to detect faults in the sensor integrated circuit.
