They per- form sampling, analog-to-digital conversion and anti- alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 100 kHz per channel. The CS5396/97 use a patented 7th-order, tri-level delta- sigma modulator followed by digital filtering and decima- tion, which removes the need for an external anti-alias filter. The ADCs use a differential architecture which pro- vides excellent noise rejection. The CS5396 has a linear phase filter optimized for audio applications with ±0.005 dB passband ripple and >117 dB stopband rejection. The CS5397 has a non- aliasing filter response with ±0.005 passband ripple and >117 dB stopband attenuation. Other features available in both the CS5396 and CS5397 are an optional low group delay filter and a unique psychoacoustic noise shaping filter which subjectively truncates the output to 16, 18 or 20 bits while 24-bit sound quality is preserved. The CS5396/97 are targeted for the highest perfor- mance professional audio systems requiring wide dynamic range, negligible distortion and low noise.
