WM9010 w Low Power, Class G Stereo Headphone Driver DESCRIPTION FEATURES Hi-fi audio headphone drivers (104dB SNR - A weighted) The WM9010 is a low power stereo headphone driver designed Stereo analogue audio inputs for mobile handset and portable media player (PMP) Ground-referenced, cap-less headphone outputs applications. Class G amplifier technology is used to achieve Integrated charge pump and oscillator circuits high power efficiency and low quiescent current. Low quiescent current Stereo analogue inputs accept 1Vrms line level inputs the Hi-Fi RF noise suppression output drivers deliver up to 28mW into a 32 load. Pop and click suppression 12-pin CSP package (1.84 x 1.34 x 0.7mm) An integrated charge pump circuit generates split-rail voltage supplies to power the ground-referenced headphone driver. APPLICATIONS The WM9010 incorporates Wolfson Silent Switch technology to provide pop and click suppression whenever the WM9010 is Mobile Handsets enabled or disabled. Portable Media Players (PMP) The WM9010 is supplied in a 12-pin CSP package.
