The WM8756 is a high performance 6-channel DAC designed for audio applications such as SACDTM players, DVD-V and DVD-A, home audio and theatre systems. The device supports data input word lengths from 16 to 32-bits and sampling rates up to 192kHz. The WM8756 can implement 2 or 6 channels at 192kHz for high-end DVDAudio, or 6 channels at up to 192kHz for surround applications. Additionally 64x DSD bitstream support is offered on all 6 channels. The WM8756 consists of a serial interface port, digital interpolation filters, multi-bit sigma delta modulators and 6 DACs in a 48-pin TQFP package. The WM8756 also includes a digitally controllable mute and attenuator function on each channel, accessible during PCM operation. An on-chip multiplexer selects between PCM or DSD audio data input pins.
