WM8736 Datasheet | Wolfson Microelectronics plc

DESCRIPTION The WM8736 is a high performance 6-channel DAC designed for audio applications such as DVD, home theatre systems, and digital TV. The WM8736 supports data input word lengths from 16 to 24-bits and sampling rates up to 96k Hz. The WM8736 consists of a serial interface port, digital interpolation filters, multi-bit sigma delta modulators and 6 DACs in a small 28-pin SSOP package. The WM8736 also includes a digitally controllable mute and attenuator function on each channel. The WM8736 supports a variety of connection schemes for audio DAC control. The SPI-patible 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. The WM8736 is an ideal device to interface to AC-3, DTS, and MPEG audio decoders for surround sound applications.
