Ultra Low Power Audio Subsystem
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.
Class G technology is integrated to increase the efficiency and extend playback time by optimizing the headphone driver supply
voltages according to the volume control.
The flexible input configuration allows single ended or differential stereo inputs.
Mixers allow highly flexible routing to ...
