DESCRIPTION
The WM8711L is a low power stereo DAC with an integrated
headphone driver. The WM8711L is designed specifically for
portable MP3 audio and speech players. The WM8711L is
also ideal for MD, CD machines and DAT players.
Stereo 24-bit multi-bit sigma delta DACs are used with
oversampling digital interpolation filters. Digital audio input
word lengths from 16-32 bits and sampling rates from 8KHz
to 96KHz are supported.
Stereo audio outputs are buffered for driving headphones
from a programmable volume control, line level outputs are
also provided along with anti-thump mute and power
up/down circuitry.
The device is controlled via a 2 or 3 wire serial interface.
The interface provides access to all features including
volume controls, mutes, de-emphasis and extensive power
management facilities. The device is available in a small 28-
lead QFN (5x5x0.9 mm body) package.
A USB mode is provided where all audio rates can be
derived from a single 12MHz or 24MHz MCLK, saving on
the need for a PLL or multiple crystals.
