General Description
The CS5340 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 CS5340 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 CS5340 is available in a 16-pin TSSOP package
for Commercial (-10° to +70° C) and Automotive grades
(-40° to +85° C). The CDB5340 Customer Demonstra-
tion Board is also available for device evaluation and
implementation suggestions. Please refer to “Ordering
Information” on page 22 for complete ordering
information.
The CS5340 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.
