w WM9010 Low Power, Class G Stereo Headphone Driver DESCRIPTION FEATURES The WM9010 is a low power stereo headphone driver designed for mobile handset and portable media player (PMP) applications. Class G amplifier technology is used to achieve high power efficiency and low quiescent current. Stereo analogue inputs accept 1Vrms line level inputs; the Hi-Fi output drivers deliver up to 28mW into a 32Ω load. An integrated charge pump circuit generates split-rail voltage supplies to power the ground-referenced headphone driver. The WM9010 incorporates Wolfson Silent Switch™ technology to provide pop and click suppression whenever the WM9010 is enabled or disabled. The WM9010 is supplied in a 12-pin CSP package.
