Description
The CS5360 is a 2-channel, single +5 V supply, 24-bit
analog-to-digital converter for digital audio systems. The
CS5360 performs sampling, analog-to-digital conversion
and anti-alias filtering, generating 24-bit values for both
left and right inputs in serial form. The output word rate
can be up to 50 kHz per channel.
The CS5360 uses 4th-order, delta-sigma modulation
with 128X oversampling followed by digital filtering and
decimation, which removes the need for an external anti-
alias filter. This ADC uses a differential architecture
which provides excellent noise rejection.
The CS5360 has a filter passband to 21.7 kHz. The filter
has linear phase, 0.0025 dB passband ripple, and
>85 dB stopband rejection. An on-chip high pass filter is
also included to remove DC offsets.
