General Description

The CS5342 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 CS5342 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 CS5342 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.
