The WM8993 is a highly integrated ultra-low power hi-fi codec designed for portable devices such as multimedia phones.
A stereo 1W/channel speaker driver can operate in class D or AB mode. Low leakage and high PSRR enable direct battery connection for the speaker supply.
Class W headphone drivers provide a dramatic reduction in playback power and are ground-referenced. Active ground loop noise rejection and DC offset correction help prevent pop noise and ground noise from degrading headphone output quality.
Powerful mixing capability allows the device to support a huge range of architectures and use cases. A highly flexible input configuration supports multiple microphone or line inputs (mono or stereo, single-ended or differential).
A fully differential internal architecture, active ground noise rejection and on-chip RF filtering ensure a very high degree of noise immunity.
ReTune™ Mobile provides powerful parametric equalization for optimizing speaker characteristics. Programmable dynamic range control is also available for maximizing loudness, protecting speakers from clipping and preventing premature shutdown due to battery droop.
The WM8993 is supplied in very small and thin 48-ball W-CSP package, ideal for portable systems.
