3.5.9 function introduction to 5340
1. DESCRIPTION
The CS5340 is complete analog-to-digital converter for digital audio systems. It performs sampling,
analog-to-digital conversion and anti-alias littering, 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 dynamic range, negligible distortion and low noise,
such as set-top boxes, DVD-karaoke players, DVD recorders, A/V receivers, and automotive applications.
