Abstract
A digital pulse width modulation driver system and method can include: receiving input digital data with a digital signal processing chip on a device; converting the input digital data into pulse width modulated data; generating an amplitude signal with the digital signal processing chip; transmitting the amplitude signal and the pulse width modulated data from a transmit interface within the device to a receive interface within an analog driver chip; and amplifying the pulse width modulated data with a driver coupled to a high voltage rail based on the amplitude signal corresponding to the high voltage rail, or amplifying the pulse width modulated data with the driver coupled to a low voltage rail based on the amplitude signal corresponding to the low voltage rail.
