Digital pulse width modulation driver system

A method of operating a digital pulse width modulation driver system comprising:

• receiving pulse code modulated data with a digital signal processing chip on a device;
• filtering the pulse code modulated data with a filter within the digital signal processing chip;
• converting the pulse code modulated data into pulse width modulated data with the digital signal processing chip;
• 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.
