The WM8706 is a high performance stereo DAC designed for audio applications such as DVD, home theatre systems, and digital TV.
The WM8706 supports data input word lengths from 16 to 32-bits and sampling rates up to 192kHz.
The WM8706 can implement 2 channels at 192kHz for highend DVD-Audio.
The WM8706 consists of a serial interface port, digital interpolation filters, multi-bit sigma delta modulators and stereo DAC in a small 28-pin SSOP package.
The WM8706 also includes a digitally controllable mute and attenuate function on each channel.
The WM8706 supports a variety of connection schemes for audio DAC control.
The MPU serial port provides access to a wide range of features including on-chip mute, attenuation and phase reversal.
A hardware controllable interface is also available.
It is pin-compatible with the WM8716 provided the oscillator circuit on WM8716 is not required in the application.
The WM8706 is an ideal device to interface to AC-3, DTS , and MPEG audio decoders for surround sound applications, or for use in DVD players supporting DVD-A.
