CS5343/4
3/10/15
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, analog-
24-bit Conversion
to-digital conversion, and anti-alias filtering, generating
24-bit values for both left and right inputs in serial form
Supports Audio Sample Rates Up to 108 kHz
at sample rates up to 108 kHz per channel.
98 dB Dynamic Range at 5 V
The CS5343/4 uses a 3rd-order, multi-bit Delta-Sigma
-92 dB THD+N at 5 V
modulator followed by a digital filter, which removes the
need for an external anti-alias filter.
Low-Latency Digital Filter
The CS5343/4 also features a high-impedance sam-
High-Pass Filter to Remove DC Offsets
pling network which eliminates costly external
components such as op-amps.
Single +3.3 V or +5 V Power Supply
The CS5343/4 is available in a 10-pin TSSOP package
Power Consumption < 40 mW at 3.3 V
for both Commercial (-40 to +85 C) and Automotive
Master or Slave Operation grades (-40 to +105 C). The CDB5343 Customer
Demonstration Board is also available for device evalu-
Slave Mode Speed Auto-Detect
ation and implementation suggestions. Please refer to
the Ordering Information on page19 for complete
Master Mode Default Settings
details.
256x or 384x MCLK/LRCK Ratio
The CS5343/4 is ideal for audio systems requiring wide
CS5343 Supports IS Audio Format dynamic range, negligible distortion and low noise, such
as set-top boxes, DVD-karaoke players, DVD record-
CS5344 Supports Left-Justified Audio Format
ers, A/V receivers, and automotive applications.
