CS5341
3/11/08
105 dB, 192 kHz, Multi-Bit Audio A/D Converter
Features General Description
Advanced Multi-bit Delta-Sigma Architecture The CS5341 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 All Audio Sample Rates Including at sample rates up to 200 kHz per channel.
192 kHz
The CS5341 uses a 5th-order, multi-bit Delta-Sigma
modulator followed by digital filtering and decimation,
105 dB Dynamic Range at 5 V
which removes the need for an external anti-alias filter.
The CS5341 is available in a 16-pin TSSOP package
-98 dB THD+N
for Commercial (-10 to +70 C) and Automotive grades
(-40 to +85 C). The CDB5341 Customer Demonstra-
90 mW Power Consumption
tion Board is also available for device evaluation and
implementation suggestions. Please refer to Ordering

information.
Analog/Digital Core Supplies from 3.3 V to 5 V
The CS5341 is ideal for audio systems requiring wide
Supports Logic Levels between 1.8 V and 5 V
dynamic range, negligible distortion and low noise, such
as set-top boxes, DVD-karaoke players, DVD record-
