General Description

The CS5343/4 is a complete analog-to-digital converter

for digital audio systems. It performs sampling, analog-

to-digital conversion, and anti-alias filtering, generating

24-bit values for both left and right inputs in serial form

at sample rates up to 108 kHz per channel.

The CS5343/4 uses a 3rd-order, multi-bit Delta-Sigma

modulator followed by a digital filter, which removes the

need for an external anti-alias filter.

The CS5343/4 also features a high-impedance sam-

pling

components such as op-amps.

The CS5343/4 is available in a 10-pin TSSOP package

for both Commercial (-40° to +85° C) and Automotive

grades (-40° to +105° C). The CDB5343 Customer

Demonstration Board is also available for device evalu-

ation and implementation suggestions. Please refer to

the

details.

The CS5343/4 is ideal for audio systems requiring wide

dynamic range, negligible distortion and low noise, such

as set-top boxes, DVD-karaoke players, DVD record-

ers, A/V receivers, and automotive applications.
