The CS5342 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 200 kHz per channel.
The CS5342 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 CS5342 is available in a 16-pin TSSOP package in
Commercial grade (-10° to 70° C). The CDB5342 Cus-
tomer Demonstration board is also available for device
evaluation and implementation suggestions. Please re-
fer to “Ordering Information” on page 21 for complete
ordering information.
The CS5342 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.
