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 (-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 “Ordering Information” on page 19 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.

ANALOG CHARACTERISTICS - COMMERCIAL GRADE (-CZZ)
Test conditions (unless otherwise specified): TA = 25C; Input test signal is a 997 Hz sine wave through recom-
mended inputs as seen in Figure 6 on page 14; source impedance less than or equal to 2.5 k; valid with FILT+
and VQ components as shown in Figure 3 on page 11; measurement bandwidth is 10 Hz to 20 kHz; Fs = 48 kHz
or 96 kHz.
