CS5360

24-Bit Stereo A/D Converter for Digital Audio

Features

– 21.7 kHz passband (Fs = 48kHz)

– 85 dB stop band attenuation

– 0.0025 dB pass band ripple

– High Resolution and Bar Graph Modes

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.
