WM8993

Audio Hub Codec for Multimedia Phones

DESCRIPTION

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 across the audio band

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).

Fully differential internal architecture and on-chip RF noise filters

ensure a very high degree of noise immunity.

ReTune

Mobile parametric EQ with fully programmable

coefficients is integrated for optimization of 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.
