ABSTRACT:
A digital amplifier system for driving a capacitive load includes a digital amplifier controller responsive to a digital input command for producing a pulse density modulation signal representative of the digital input command; a switching amplifier for amplifying the pulse density modulation signal and an inductive filter for demodulating the amplified pulse density modulation signal to provide a drive current to drive a capacitive load in response to the digital input command.
