The output word rate can be up to 50 kHz per channel.
The ADCs CS5336 use delta-sigma modulation with 64X oversampling, 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 24kHz. The filters have linear phase, 0.01 dB passband ripple, and >80 dB stopband rejection.
The ADC's CS5336 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.
