Abstract
A closed loop amplifier adapted to be directly connected to a battery having a battery voltage for powering the amplifier. The amplifier includes an amplifier stage having a node for receiving a control voltage for controlling a common mode voltage of the stage, a digital voltage indicator for generating a digital value corresponding to the battery voltage, and a common mode voltage supply providing the control voltage corresponding to the digital value.
