CS5340 - MULTI-BIT AUDIO A/D CONVERTER

General Description

The CS5340 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 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.
