CS5335

The CS5334 and CS5335 are 2-channel, single +5 V supply, pin compatible analog-to-digital converters for digital audio systems. The CS5334 and CS5335 perform sampling, analog-to-digital conversion and anti-alias filtering,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 21.7 kHz. The filter has linear phase, 0.0025 dB pass-band ripple, and >85 dB stopband rejection. An onchip high pass filter is also included to remove DC offsets.
