WM8785

24-Bit, 192kHz Stereo ADC

DESCRIPTION

FEATURES

•

SNR 111dB (‘A’ weighted @ 48kHz)

THD -102dB (at -0.1dB)

Sampling Frequency: 8 – 192kHz

2 or 3 Wire Microprocessor Control Interface

Master or Slave Clocking Mode

The WM8785 is a stereo audio ADC with differential inputs

designed for high performance recordable media applications.

Data is provided as a PCM output.

Stereo 24-bit multi-bit sigma-delta ADCs are used with digital

audio output word lengths of 16 to 32 bits, and sampling rates

from 8kHz to 192kHz. The device has a selectable high pass

filter to remove residual DC offsets. The device also supports a

TDM bus for data out.

Programmable Audio Data Interface Modes

I²S, Left, Right Justified or DSP

16/20/24/32 bit Word Lengths

•

A TDM bus is supported for data out

Supply Voltages

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

interface provides access to all features including oversampling

rate, audio format, powerdown, master/slave control and digital

signal manipulation. The device is supplied in a 20-lead SSOP

package.

Analogue 4.5 to 5.5V

Digital core: 2.7V to 3.6V

•

20-lead SSOP package

APPLICATIONS

•

Recordable DVD Players

Personal Video Recorders

High End Sound Cards

Studio Audio Processing Equipment
