WM9081 Overview
The WM9081 is designed to provide high power output at low distortion levels in space-constrained portable applications. 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.
