The WM9010 is a stereo headphone driver that utilizes Class G amplifier technology to achieve high power efficiency and low quiescent current. Stereo analog inputs accept 1 VRMS line level inputs and the Hi-Fi output drivers deliver up to 28 mW into a 32-ohm load. An integrated charge pump circuit generates split rail voltage supplies to power the ground-referenced headphone driver. The WM9010 provides pop and click suppression whenever the WM9010 is enabled or disabled.
