CS5343/4
98 dB, 96 kHz, Multi-Bit Audio A/D Converter
Features
General Description
Advanced Multi-Bit Architecture
The CS5343/4 is a complete analog-to-digital converter
for digital audio systems. It performs sampling, analogto-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.
24-bit Conversion
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 sampling 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
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 evaluation and implementation suggestions. Please refer to
the “Ordering Information” on page 19 for complete
details.
Power Consumption < 40 mW at 3.3 V

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 recorders, A/V receivers, and automotive applications.
