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.
