WM8590

24-bit, 192kHz Stereo CODEC

DESCRIPTION

FEATURES

•

Audio Performance

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.

−

110dB SNR (‘A’ weighted @ 48kHz) DAC

102dB SNR (‘A’ weighted @ 48kHz) ADC

•

DAC Sampling Frequency: 32kHz – 192kHz

ADC Sampling Frequency: 32kHz – 96kHz

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.

Stereo ADC input analogue gain adjust from +24dB to –21dB in

0.5dB steps

•

ADC digital gain from -21.5dB to -103dB in 0.5dB steps

Programmable Limiter on ADC input.

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.

Stereo DAC with differential analogue line outputs.

3-Wire SPI Compatible Control Interface

Master or Slave Clocking Mode

The WM8590 supports fully independent sample rates for the

ADC and DAC. The audio data interface supports I²S, left

justified, right justified and DSP formats.

Programmable Audio Data Interface Modes

−

I²S, Left, Right Justified or DSP

16/20/24/32 bit Word Lengths

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.

•

4.5V to 5.5V Analogue, 2.7V to 3.6V Digital supply Operation

28-lead SSOP Package

APPLICATIONS

•

Surround Sound AV Processors and Hi-Fi systems

DVD-RW
