General Description
The CS5351 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 192 kHz per channel.
The CS5351 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 CS5351 is ideal for audio systems requiring wide dy-
namic range, negligible distortion and low noise, such as
A/V receivers, DVD-R, CD-R, digital mixing consoles,
and effects processors.
