CS5334 CS5335  
20-Bit, Stereo A/D Converter for Digital Audio  
Features  
General Description  
The CS5334 and CS5335 are 2-channel, single +5V  
supply, pin compatable analog-to-digital converters for  
digital audio systems. The CS5334 and CS5335 perform  
sampling, analog-to-digital conversion and anti-alias fil-  
tering, generating 20-bit values for both left and right  
inputs in serial form. The output word rate can be up to  
50 kHz per channel.  
CS5334  
Dynamic Range: 100 dB  
THD+N: -90 dB  
CS5335  
Dynamic Range: 105 dB  
THD+N: -95 dB  
The CS5334 and CS5335 use 4th-order, delta-sigma  
modulation with 128X oversampling followed by digital  
filtering and decimation, which removes the need for an  
external anti-alias filter. These ADCs use a differential  
architecture which provides excellent noise rejection.

Linear Phase Digital Anti-Alias Filtering  
21.7 kHz passband (fs = 48kHz)  
85 dB stop band attenuation  
The CS5334 and CS5335 have a filter passband to  
21.7kHz. The filter has linear phase, 0.0025 dB pass-  
band ripple, and >85 dB stopband rejection. An on-chip  
high pass filter is also included to remove DC offsets.
