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 network which eliminates costly external
components such as op-amps.
The CS5343/4 is available in a 10-pin TSSOP package
for both Commercial (-10° to +70° C) and Automotive
grades (-40° to +85° C). The CDB5343 Customer Dem-
onstration Board is also available for device evaluation
and implementation suggestions. Please refer to the
“Ordering Information” on page 21 for complete 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.
