High-performance audio DAC drives novel CD player
Wolfson's high-performance stereo digital-analogue conversion technology is at the heart of two new CD players introduced by hi-fi specialist Rega Research.
Stereo DAC supports Direct Stream Digital
Wolfson Microelectronics has unveiled its first stereo DAC with support for the Direct Stream Digital (DSD) audio data format.
Class D integrated circuits are critical to the building of multichannel high-performance audio systems with minimal power consumption for portable digital audio products.
The WM8960's Class D speaker driver can deliver up to 1W continuously (1% THD into 8ohm) and features synchronous clocking with the DAC for low noise and pop and click suppression.
The WM8960 also has a capless headphone driver mode, removing the need for bulky external components.
As befits a device for portable applications, the WM8960 consumes 10mW in playback mode, making it one of the lowest power devices of its kind.
The highly flexible input configuration of the WM8960 includes a complete stereo single-ended or pseudo-differential microphone interface and up to three stereo analogue sources to eliminate external analogue switches.
"As the demand for high-quality, low power portable audio products continues to grow, Wolfson is committed to providing innovative components employing Class D technology", said Yan Goh, Wolfson Product Marketing Manager.
The WM8960 is available for sampling in a compact 5 x 5mm QFN package.
