DESCRIPTION
FEATURES
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. ReTuneTM 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.
