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.
