General Description
The CS5330A / 31A is a complete stereo analog-to-
digital converter which performs anti-alias filtering,
sampling and analog-to-digital conversion generating
18-bit values for both left and right inputs in serial form.
The output sample rate can be infinitely adjusted be-
tween 2 and 50 kHz.
The CS5330A / 31A operates from a single +5V supply
and requires only 150 mW for normal operation, mak-
ing it ideal for battery-powered applications.
The ADC uses delta-sigma modulation with 128X over-
sampling, followed by digital filtering and decimation,
which removes the need for an external anti-alias filter.
The linear-phase digital filter has a passband to
21.7 kHz, 0.05 dB passband ripple and >80 dB stop-
band rejection. The device also contains a high pass
filter to remove DC offsets.
The device is available in a 0.208" wide, 8-pin surface
mount package.
