WM8775

24-bit, 96kHz ADC with 4 Channel I/P Multiplexer

DESCRIPTION

FEATURES

•

Audio Performance

The WM8775 is a high performance, stereo audio ADC

with a 4 channel input mixer. The WM8775 is ideal for

digitising multiple analogue sources for surround sound

processing applications for home hi-fi, automotive and

other audio visual equipment.

−

102dB SNR (‘A’ weighted @ 48kHz)

-90dB THD

•

ADC Sampling Frequency: 32kHz – 96kHz

Four stereo ADC inputs with analogue gain adjust from

+24dB to –21dB in 0.5dB steps

A stereo 24-bit multi-bit sigma delta ADC is used with a

four stereo channel input selector. Each channel has

programmable gain control. Digital audio output word

lengths from 16-32 bits and sampling rates from 32kHz

to 96kHz are supported.

•

Digital gain adjust from -21.5dB to -103dB.

Programmable Automatic Level Control (ALC) or Limiter on

ADC input

•

3-Wire SPI Compatible or 2-wire Serial Control Interface

Master or Slave Clocking Mode

The audio data interface supports I²S, left justified, right

justified and DSP digital audio formats.

Programmable Audio Data Interface Modes

I²S, Left, Right Justified or DSP

The device is controlled via a 2 or 3 wire serial interface.

The interface provides access to all features including

channel selection, volume controls, mutes, de-emphasis

and power management facilities.

−

16/20/24/32 bit Word Lengths

•

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

The device is available in a 28-lead SSOP package. The

WM8775 is software compatible with the WM8776.

APPLICATIONS

•

Surround Sound AV Processors and Hi-Fi systems

Automotive Audio
