WM8718

24 Bit Differential Stereo DAC with Volume Control

DESCRIPTION

FEATURES

•

24 bit Stereo DAC

The WM8718 is a high performance differential stereo DAC

designed for audio applications such as DVD, home theatre

systems and digital TV. The WM8718 supports PCM data

input word lengths from 16 to 32-bits and sampling rates up

to 192kHz. The WM8718 consists of a serial interface port,

digital interpolation filters, multi-bit sigma delta modulators

and differential stereo DAC in a small 20-lead SSOP

package or 24-lead QFN package. The WM8718 includes a

digitally controllable mute, an attenuate function and zero

flag output for each channel.

Fully Differential Voltage Outputs

Audio Performance

111dB SNR (‘A’ weighted @ 48kHz) DAC

-100dB THD

•

DAC Sampling Frequency: 8kHz - 192kHz

3 Wire Serial Control Interface

Programmable Audio Data Interface Modes

I²S, Left, Right Justified, DSP

The 3-wire serial control port provides access to a wide

range of features including on-chip mute, attenuation and

phase reversal.

16/20/24/32 bit Word Lengths

•

Independent Digital Volume Control on Each Channel with

127.5dB Range in 0.5dB Steps

•

Independent Zero Flag Outputs

The WM8718 is an ideal device to interface to AC-3,

DTS, and MPEG audio decoders for surround sound

applications, or for use in DVD players including those

supporting DVD-A.

3.0V - 5.5V Supply Operation

20-lead SSOP Package or 24-lead QFN Package

APPLICATIONS

•

CD, DVD, and DVD-Audio Players

Home theatre systems

Professional mixing desks
