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: (1)Games consoles; (2)Portable media / DVD players; (3)Mobile multimedia.
