General Description
The CS5336, CS5338 & CS5339 are complete analog-
to-digital converters for stereo digital audio systems.
They perform sampling, analog-to-digital conversion and
anti-aliasing filtering, generating 16-bit values for both
left and right inputs in serial form. The output word rate
can be up to 50 kHz per channel.
The ADCs use delta-sigma modulation with 64X over-
sampling, followed by digital filtering and decimation,
which removes the need for an external anti-alias filter.
The CS5336 & CS5338 have an SCLK which clocks out
data on rising edges. The CS5339 has an SCLK which
clocks out data on falling edges.
The CS5336 has a filter passband of dc to 22kHz. The
CS5338 & CS5339 have a filter passband of dc to 24
kHz. The filters have linear phase, 0.01 dB passband
ripple, and >80 dB stopband rejection.
The ADC’s are housed in a 0.6" wide 28-pin plastic DIP,
and also in a 0.3" wide 28-pin SOIC surface mount
package. Extended temperature range versions of the
CS5336 are also available.
