WM8740

24-bit, High Performance 192kHz Stereo DAC

DESCRIPTION

FEATURES

•

120dB SNR (‘A’ weighted mono @48kHz), THD+N: -104dB

@ FS

117dB SNR (‘A’ weighted stereo @48kHz), THD+N: -104dB

@ FS

Sampling frequency: 8kHz to 192kHz

Selectable digital filter roll-off

Optional interface to industry standard external filters

Differential mono mode needing no glue logic

Input data word: 16 to 24-bit

The WM8740 is a very high performance stereo DAC

designed for audio applications such as CD, DVD, home

theatre systems, set top boxes and digital TV. The WM8740

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

sampling rates up to 192kHz. The WM8740 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 WM8740 also includes a digitally controllable

mute and attenuator function on each channel.

•

Hardware or SPI compatible serial port control modes:

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 WM8740

used with an external digital filter.

Hardware mode: mute, de-emphasis, audio format

control

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

steps), phase reversal

•

Fully differential voltage outputs

The WM8740 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

Professional audio systems
