WM8716

High Performance 24-bit, 192kHz Stereo DAC

Production Data, April 2001, Rev 3.1

DESCRIPTION

FEATURES

•

112dB SNR (‘A’ weighted @ 48kHz), THD: -97dB @

-1dB FS

The WM8716 is a high performance stereo DAC designed

for audio applications such as CD, DVD, home theatre

systems, set top boxes and digital TV. The WM8716

supports data input word lengths from 16 to 24-bits and

sampling rates up to 192kHz. The WM8716 consists of a

serial interface port, digital interpolation filter, multi-bit sigma

delta modulator and stereo DAC in a small 28-pin SSOP

package. The WM8716 also includes a digitally controllable

mute and attenuator function on each channel.

•

Sampling frequency: 8kHz to 192kHz

Selectable digital filter roll-off

Optional interface to industry standard external filters

Differential mono mode

Input data word: 16 to 24-bit

Hardware or SPI compatible serial port control modes:

−

Hardware mode: mute, de-emphasis, audio format

control

The internal digital filter has two selectable roll-off

characteristics. A sharp or slow roll-off can be selected

dependent on application requirements. Additionally, the

internal digital filter can be by-passed and the WM8716

used with an external digital filter.

−

Serial mode: mute, de-emphasis, attenuation (256

steps), phase reversal

•

Compatible upgrade to PCM1716

The WM8716 supports two connection schemes for audio

DAC control. The SPI-compatible serial control port

provides access to a wide range of features including on-

chip mute, attenuation and phase reversal. A hardware

controllable interface is also available.

APPLICATIONS

•

CD, DVD audio

Home theatre systems
