WM8788

High Performance 24-bit Stereo ADC

DESCRIPTION

FEATURES

•

Hi-Fi audio ADC

The WM8788 is

designed for LCD televisions, DVD, Blu-Ray and set-top box

applications.

a high performance 24-bit stereo ADC

106dB SNR (‘A’ weighted

-91dB THD (-1dBFS output)

Sample rates 8kHz to 192kHz

A stereo pair of analogue inputs is provided; external resistors

are used to configure the device for line level inputs at 1Vrms or

for higher input signal levels. The Hi-Fi ADCs output 16, 20 or

24-bit stereo data on the digital audio interface.

•

2 analogue audio inputs

Support for line level inputs >1Vrms

Digital audio interface

Master or Slave operation

16, 20 or 24-bit data format

Right-justified, Left-justified, I2S modes

ADC sample rates from 8kHz to 192kHz are supported; Master

Clock (MCLK) ratios of 128fs up to 768fs are possible (fs =

sample rate).

•

Wide range of master clock (MCLK) rates

128fs, 192fs, 256fs, 384fs, 512fs, 768fs support

The digital audio interface operates in Master or Slave modes,

and supports Right-justified, Left-justified and I2S modes,

selectable using hardware control pins.

•

Hardware configuration control

Integrated voltage reference circuits

Single 3.3V supply

16-pin TSSOP package

The WM8788 is powered from a single 3.3V supply rail,

connected to the AVDD and REFVDD pins.

A power on reset (POR) circuit ensures correct start-up and

shut-down. The device is held in reset when MCLK is not

present, offering a low-power standby state.

APPLICATIONS

•

LCD televisions

Set-top boxes (STB)

Blu-Ray / DVD players and recorders

The WM8788 is supplied in a 16-pin TSSOP package.
