New input devices introduced by Wolfsun Microelectronics

August 28, 2003

Edinburgh, UK, Wolfson Microelectronics have introduced a new family of multi-channel input devices for the next generation of Class-D DVD players, AV receivers, digital set-top boxes and digital effects processors and recordable media. The WM8776 and WM8778 CODECs, and the WM8775 ADC are one of the first of their kind on the market to provide a dedicated solution for emerging recordable media technologies and digital amplifiers.

"Digital media is about to enter a new level of performance and quality that will push current mixed-signal semiconductors to their limits," said David Milne, CEO and managing director for Wolfson. "The introduction of the WM877X family, based on the proven technology of the WM8770, provides not only the integration to meet that new level, but the capacity to help the new technology grow."

The WM8776 stereo CODEC is the most highly integrated device of the family with five stereo ADC inputs with analogue gain adjustable from +24dB to -21dB in 0.5dB steps. The device also features a stereo DAC with independent analogue and digital volume controls, and stereo headphone and line output.

All three products feature automatic level control on the ADC input. The user can set a pre-determined maximum analogue signal level in order to prevent the ADC input full scale voltage from being exceeded. The automatic level control will progressively ramp down the gain and limit the signal magnitude to the pre-determined limit.
