WM8741

24-bit 192kHz DAC with Advanced Digital Filtering

DESCRIPTION

FEATURES

•

Advanced Ultra High Performance Multi-bit Sigma-Delta

Architecture

The WM8741 is a very high performance stereo DAC

designed for audio applications such as professional

recording systems, A/V receivers and high specification CD,

DVD and home theatre systems. The device supports PCM

data input word lengths from 16 to 32-bits and sampling

rates up to 192kHz. The WM8741 also supports DSD bit-

stream data format, in both direct DSD and PCM-converted

DSD modes.

−

128dB SNR (‘A’-weighted mono @ 48kHz)

125dB SNR (‘A’-weighted stereo @ 48kHz)

123dB SNR (non-weighted stereo @ 48kHz)

-100dB THD @ 48kHz

Differential analogue voltage outputs

High tolerance to clock jitter

•

PCM Mode

The WM8741 includes fine resolution volume and soft mute

control, digital de-emphasis and a range of advanced digital

filter responses, followed by a digital interpolation filter,

multi-bit sigma delta modulator and stereo DAC. Wolfson’s

patented architecture optimises the linearity of the DAC and

provides maximum insensitivity to clock jitter.

−

Sampling frequency: 32kHz to 192kHz

Input data word length support: 16 to 32-bit

Supports all standard audio interface formats

Selectable advanced digital filter responses

−

Includes linear/minimum phase and range of

tailored characteristics

−

Enables low pre-ringing, minimal latency

The digital filters include several selectable roll-off and

performance characteristics. The user can select between

standard sharp or slow roll-off responses. In addition, the

WM8741 includes a selection of advanced digital filter

characteristics including non-half band filters and minimum

phase filters.

−

Optional interface to industry standard external filters

Digital volume control in 0.125dB steps with soft ramp

and soft mute

Anti-clipping mode to prevent distortion even with input

signals recorded up to 0dB

−

Selectable de-emphasis support

Zero Flag output

This flexibility provides

range of benefits, such as

significantly reduced pre-ringing and minimal group delay.

The internal digital filters can also be by-passed and the

WM8741 used with an external digital filter.

•

DSD Mode

−

DSD bit-stream support for SACD applications

Support for normal or phase modulated bit-streams

Direct or PCM converted DSD paths (DSD Plus)

DSD mute

The WM8741 supports two connection schemes for audio

DAC control. The 2/3 wire serial control interface provides

access to all features. A range of features can also be

accessed by hardware control interface.

Hardware or software control modes:

2 and 3 wire serial control interface support

Pin compatible with WM8740

4.5V to 5.5V analogue, 3.0V to 3.6V digital supply operation

28-lead SSOP Package

−

•

The WM8741 is available in

a convenient 28-SSOP

package, and is pin compatible with the WM8740.

APPLICATIONS

•

Professional audio systems

CD, DVD, SACD audio

Home theatre systems

A/V receivers
