1 / 64 page ![]() w WM8741 24-bit 192kHz DAC with Advanced Digital Filtering WOLFSON MICROELECTRONICS plc To receive regular email updates, sign up at http://www.wolfsonmicro.com/enews Production Data, October 2009, Rev 4.2 Copyright ©2009 Wolfson Microelectronics plc DESCRIPTION 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. 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. 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. This flexibility provides a 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. 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. The WM8741 is available in a convenient 28-SSOP package, and is pin compatible with the WM8740. FEATURES • Advanced Ultra High Performance Multi-bit Sigma-Delta Architecture − 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 − 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 − 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 • 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 • 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 APPLICATIONS • Professional audio systems • CD, DVD, SACD audio • Home theatre systems • A/V receivers |
