CS5343/4

98 dB, 96 kHz, Multi-Bit Audio A/D Converter

Features

General Description

Advanced Multi-Bit ∆Σ Architecture

24-bit Conversion

The CS5343/4 is a complete analog-to-digital converter

for digital audio systems. It performs sampling, analog-

to-digital conversion, and anti-alias filtering, generating

24-bit values for both left and right inputs in serial form

at sample rates up to 108 kHz per channel.

Supports Audio Sample Rates Up to 108 kHz

98 dB Dynamic Range at 5 V

The CS5343/4 uses a 3rd-order, multi-bit Delta-Sigma

modulator followed by a digital filter, which removes the

need for an external anti-alias filter.

-92 dB THD+N at 5 V

Low-Latency Digital Filter

The CS5343/4 also features a high-impedance sam-

pling network which eliminates costly external

components such as op-amps.

High-Pass Filter to Remove DC Offsets

Single +3.3 V or +5 V Power Supply

Power Consumption < 40 mW at 3.3 V

Master or Slave Operation

The CS5343/4 is available in a 10-pin TSSOP package

for both Commercial (-40° to +85° C) and Automotive

grades (-40° to +105° C). The CDB5343 Customer

Demonstration Board is also available for device evalu-

ation and implementation suggestions. Please refer to

the “Ordering Information” on page 20 for complete

details.

Slave Mode Speed Auto-Detect

Master Mode Default Settings

256x or 384x MCLK/LRCK Ratio

CS5343 Supports I²S Audio Format

CS5344 Supports Left-Justified Audio Format

The CS5343/4 is ideal for audio systems requiring wide

dynamic range, negligible distortion and low noise, such

as set-top boxes, DVD-karaoke players, DVD record-

ers, A/V receivers, and automotive applications.
