WM9094 Description

The WM9094[1] is a high performance low power audio subsystem, including headphone driver and Class AB/D earpiece/speaker driver. The Class D speaker driver supports 650mW output power at 3.6V, 1%THD. The unique dual mode charge pump architecture provides ground referenced headphone outputs removing the requirement for external coupling capacitors.
