WM8904CGEFL - Brand New Interface - CODECs
-
Description
The WM8904 is a high performance ultra-low power stereo CODEC optimised for portable audio applications. The device features stereo ground-referenced headphone amplifiers using the Wolfson ‘Class-W’ amplifier techniques incorporating an innovative dual-mode charge pump architecture to optimise efficiency and power consumption during playback. The ground-referenced headphone and line outputs eliminate AC coupling capacitors, and both outputs include common mode feedback paths to reject ground noise.
