Wolfson Microelectronics announces an addition to its portfolio of high performance DACs. The WM8742 is targeted at professional audio applications and addresses the increasing demands of high-end home audio applications such as A/V receivers, CD, DVD, SACD and home theatre systems. The new 24-bit 192kHz DAC device combines an exceptional signal to noise ratio of 123dB (stereo) with Wolfson's low out-of-band noise, world-class linearity and a unique combination of programmable advanced digital filters. This suite of filters overcomes the limitations and listening issues found in existing high-end audio systems such as pre-ringing and latency, which can distort the playback giving some systems a cold and artificial feel. WM8742 shapes the audio to the ideal listening conditions recreating the optimal natural analogue sound.
"The response from the professional audio industry to our new digital filter technology has been outstanding. There is a clear demand for this calibre of audio performance in a wide range of high-end audio applications," commented John Crawford, high performance audio manager at Wolfson. "The WM8742 brings Wolfson's authentic, natural sounding high performance audio to a larger market".
The WM8742 can be configured to meet the performance requirements of demanding audio applications by tailoring the audio filtering to the required listening experience. The in-built advanced digital filter options, unique to Wolfson's high performance DAC portfolio, provides a high degree of control over the many parameters which affect the audio output and gives users the choice of different characteristics including group delay, phase and latency, impulse response and transition band roll off. This flexibility significantly reduces pre-ringing and gives maximum insensitivity to clock jitter. By removing the need for external digital filters the WM8742 also reduces external component count and therefore cost.
Utilising Wolfson's unique low order modulator and multi-bit DAC architecture the WM8742 achieves low out-of-band noise and world-class linearity for outstanding sound quality. The WM8742 is a complete differential stereo audio DAC system with a range of audio interface options. The system includes a dithered digital interpolation filter, fine resolution volume control and digital enabled de-emphasis, as well as a multi-bit sigma delta modulator and switched capacitor multi-bit stage with differential voltage outputs. The WM8742 is also pin-compatible with the WM8740 and WM8741.
Maybe Classé will incorporate this in the upgraded SSP-800?
