General Description

The CS5361 is a complete analog-to-digital converter for
digital audio systems. It performs sampling, analog-to-
digital conversion, and anti-alias filtering. The CS5361
generates 24-bit values for both left and right inputs in
serial form at sample rates up to 192 kHz per channel.
The CS5361 uses a 5th-order, multi-bit, delta-sigma
modulator followed by digital filtering and decimation.
This removes the need for an external anti-alias filter.
The ADC uses a differential architecture which provides
excellent noise rejection.
The CS5361 is ideal for audio systems requiring wide dy-
namic range, negligible distortion, and low noise. These
applications include A/V receivers, DVD-R, CD-R, digital
mixing consoles, and effects processors.
