A switchable amplifier and comparator circuit includes an operational amplifier having an inverting input, a non-inverting input, a first differential output and a second differential output, the first differential output switchably coupled to the inverting input and the second differential output switchably coupled to the non-inverting input. A first feedback capacitor is coupled to the inverting input and switchably coupled to the first differential output, a second feedback capacitor is coupled to the non-inverting input and switchably coupled to the second differential output. A capacitive load is switchably coupled between the first differential output and the second differential output. A diode clamp circuit is switchably coupled between the first differential output and the second differential output. A resistive load is switchably coupled between the first differential output and the second differential output.
