Abstract
A system comprises a switched capacitor amplifier including an operational amplifier (opamp). A switching circuit comprises a first switch connected across inputs of the opamp. A second switch is connected across outputs of the opamp. An overdrive detect circuit communicates with the first and second switches and selectively shorts the inputs and the outputs of the opamp when the input voltage is greater than a first predetermined overdrive voltage or when the input voltage is less than a second predetermined overdrive voltage.
