1 / 20 page Features • CS5334 Dynamic Range: 100 dB THD+N: -90 dB • CS5335 Dynamic Range: 105 dB THD+N: -95 dB • 128X Oversampling • Fully Differential Inputs • Linear Phase Digital Anti-Alias Filtering 21.7 kHz passband (fs = 48kHz) 85 dB stop band attenuation 0.0025 dB pass band ripple • High Pass Filter - DC offset removal • Peak Signal Level Detector High Resolution and Bar Graph Modes 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. 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. 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. ORDERING INFORMATION: Model Temp.
