The CS5340 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 CS5340 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 CS5340 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.
