General Description

The CS5351 is a complete analog-to-digital converter

for digital audio systems. It performs sampling, analog-

to-digital conversion, and anti-alias filtering. The device

generates 24-bit values for both left and right inputs in

serial form at sample rates up to 192 kHz per channel.

The CS5351 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 ADC uses a differential architecture which provides

excellent noise rejection.

The CS5351 is ideal for audio systems requiring wide

dynamic range, negligible distortion, and low noise.

Such applications include A/V receivers, DVD-R, CD-R,

digital mixing consoles, and effects processors.
