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.
