General Description

The CS5343/4 is a complete analog-to-digital converter for digital audio systems.

It performs sampling, analogto-digital conversion, and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 108 kHz per channel.

The CS5343/4 uses a 3rd-order, multi-bit Delta-Sigma modulator followed by a digital filter, which removes the need for an external anti-alias filter.

Overview

Draft 3/10/15 CS5343/4 98 dB, 96 kHz, Multi-Bit Audio A/D Converter.
