WM8959 General Description
The WM8959 is an ultra-low power hi-fi DAC designed for multimedia handsets.
A powerful 1W speaker driver can operate in class D or AB modes, providing total flexibility to the system designer. Low leakage, high PSRR and pop/click suppression enable direct battery connection for the speaker supply.
A flexible input configuration supports two microphone inputs (single-ended or differential), a stereo line input, and a mono differential line input. Four headphone drivers support fully differential headset drive, providing excellent crosstalk performance and bass response, maximising stereo effects, and allowing the removal of large and expensive headphone capacitors.
The headphone outputs can also be configured to drive an ear speaker. A fully differential path to these outputs direct from the input pins is available to maximise signal quality and minimise power consumption. Stereo 24-bit sigma-delta DACs provide hi-fi quality audio playback, with a flexible digital audio interface supporting most commonly-used clocking schemes. An integrated low power PLL provides additional flexibility.
The WM8959 is supplied in very small and thin 42-ball WCSP package, ideal for portable systems.
