WM8960GEFL

Product Summary

The WM8960GEFL is a low power, high quality stereo codec designed for portable digital audio applications. Stereo class D speaker drivers provide 1W per channel into 8Ω loads with a 5V supply. Low leakage, excellent PSRR and pop/click suppression mechanisms also allow direct battery connection to the speaker supply. Flexible speaker boost settings allow speaker output power to be maximised while minimising other analogue supply currents. A highly flexible input configuration for up to three stereo sources is integrated, with a complete microphone interface. External component requirements of the WM8960GEFL are drastically reduced as no separate microphone, speaker or headphone amplifiers are required. The applications of the WM8960GEFL include Games consoles, Portable media / DVD players, Mobile multimedia.
