Abstract

A circuit has an analog-to-digital converter that, during a first mode of the circuit, is configured to use capacitors of the converter to furnish a digital representation of an analog input voltage. The circuit also has an amplifier that has a gain responsive to a capacitance, and the switches are configured to, during a second mode of the circuit, selectively connect the capacitors to the amplifier to select the gain.
