WM8750BG Integrated Circuitry Amplifier - Premium Audio/Video Amplifier IC for Multimedia Applications

The WM8750BL is a low power, high quality stereo CODEC designed for portable digital audio applications. The device integrates complete interfaces to stereo or mono microphones and a stereo headphone. External component requirements are drastically reduced as no separate microphone or headphone amplifiers are required. Advanced on-chip digital signalprocessing performs graphic equaliser, 3-D sound enhancement and automatic level control for the microphone or line input.
