24-bit, 192kHz Stereo CODEC
DESCRIPTION
The WM8590 is a high performance, stereo audio codec with
differential inputs and outputs. It is ideal for surround sound
processing applications for home hi-fi, DVD-RW and other
audio visual equipment.
The stereo 24-bit multi-bit sigma delta ADC has programmable
gain with limiting control. Digital audio output word lengths from
16-32 bits and sampling rates from 32kHz to 96kHz are
supported.
A stereo multi-bit sigma delta DAC is used with digital audio
input word lengths from 16-32 bits and sampling rates from
32kHz to 192kHz.
The WM8590 supports fully independent sample rates for the
ADC and DAC. The audio data interface supports I

S, left
justified, right justified and DSP formats.
The device is controlled in software via a 3 wire serial interface
which provides access to all features including volume controls,
mutes, and de-emphasis facilities. The device is available in a
28-lead SSOP package.
