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.
Operating on split analogue/digital power supplies, the WM8759 allows very low power consumption (as low as 20mW on 2.7V supplies), less than 10uA in standby, but supporting large output power from the headphone driver.
The device has been rated at 100dB signal/noise ratio (SNR), "A" weighted at 48kHz, with -88dB THD driving a line load and -72dB THD driving 16ohm headphones.
The WM8759 includes a hardware control interface for selection of audio data formats, a serial interface port, digital interpolation filters and multibit sigma-delta modulators.
The device operates on 2.7 to 5.5V supplies and features a low-power standby mode controlled by a dedicated pin.
"Audio performance on headphones has become an increasingly significant issue for the next generation of both portable and home digital entertainment systems", said David Milne, Wolfson's CEO and Managing Director.
"The WM8759 gives designers a greater level of performance options to choose from at affordable prices".
The WM8759 is housed in a 14-pin SOIC.
