WOLFSON Microelectronics has introduced a comprehensive family of low-cost, power-efficient multi-channel digital analogue converters (DACs).
The six-channel WM8796, WM8766, WM8765, WM8764 and WM8763 and the two-channel WM8792 provide power-saving operation at a low cost with good performance for the next generation of DVD and super audio compact disc (SACD) players.
The WM8796 (six channel) and the WM8792 (two channel) support both pulse coded modulation (PCM), the uncompressed format in which CDs and DVDs are recorded, and direct stream digital (DSD) format for SACD.
The WM8796 and the WM8792 combine both formats onto a common interface, reducing the number of pins to support both PCM and DSD. The other components in the family support PCM only.
The WM8765, WM8764 and WM8763 are economical options featuring hardware-only interfaces with a choice of audio data interface modes. The WM8763 interface is 16 to 24 bit I2S, the WM8764 is 16 to 24 bit left justified and the WM8765 is 24 bit right justified.
The new DAC family has a 103dB signal to noise ratio ("A" weighted at 48kHz). All devices support sample rates up to 192kHz.
The WM8766 and the WM8796 feature master and slave audio interfaces. The family’s other devices act as a slave interface only.
