WM8711L

Internet Audio DAC with Integrated Headphone Amplifier

DESCRIPTION

FEATURES



Audio Performance

DAC SNR 90dB (‘A’ weighted) at AVDD = 1.8V

Low Power Headphone Playback

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.



Down to 6mW at 1.8V

1.42 – 3.6V Digital Supply Operation

1.8 – 3.6 V Analogue Supply Operation

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.



DAC Sampling Frequency: 8KHz – 96KHz

2 or 3-Wire MPU Serial Control Interface

Programmable Audio Data Interface Modes

I²S, Left, Right Justified or DSP

16/20/24/32 bit Word Lengths

Master or Slave Clocking Mode

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.



Stereo Audio Outputs

Output Volume and Mute Controls

Highly Efficient Headphone Driver

28-lead QFN (5x5x0.9 mm) package

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.

APPLICATIONS



Portable MP3 Players

CD and Minidisc Players

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.
