CS5341
105 dB, 192 kHz, Multi-Bit Audio A/D Converter
Features
General Description
Advanced Multi-bit Delta-Sigma Architecture
24-bit Conversion
Supports all audio sample rates including
192 kHz.
105 dB Dynamic Range at 5 V
-98 dB THD+N
High-pass Filter to Remove DC Offsets
Analog/digital Core Supplies from 3.3 V to
5V
Supports logic levels between 1.8 V and 5 V.
Low-latency Digital Filter
Auto-mode Selection
The CS5341 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 200 kHz per channel.
The CS5341 uses a 5th-order, multi-bit Delta-Sigma
modulator followed by digital filtering and decimation,
which removes the need for an external anti-alias filter.
The CS5341 is ideal for audio systems requiring wide dy-
namic range, negligible distortion and low noise, such as
set-top boxes, DVD-karaoke players, DVD recorders,
A/V receivers, and automotive applications.
