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.
The WM9711L uses the AC97 audio interface to eliminate hidden extra power consumption often found in older codec designs and avoids CPU loading for the best possible full split-rate sample rate support.
The new codec can be connected directly to mono or stereo headphones and microphones or mono speakers to reduce total component count in a system.
Headphone output and five GPIO pins allow seamless integration with wireless communication devices or other digital systems.
Audio mixing features include a superior bass boost function that provides more bass gain at low input levels.
"The WM9711L makes it possible to not only make a phone call, but record the call, make voice notes, record MP3 files and play them during the call", said David Milne, CEO and Managing Director for Wolfson.
"No other competing product offers the functionality of this component".
The WM9711L cuts power consumption by more than half compared with similar devices on the market, running from supply voltages between 1.8 and 3.6V and core voltages down to 1.42V.
This has been achieved through the use of low-power silicon technology and power efficient design of the analogue circuit blocks.
The WM9711L operates on 1.8 to 3.6V supplies and is supplied in a leadless, chip-scale QFN package with 7 x 7mm-body size and is available now.
Device drivers for selected platforms and operating systems are also available.
