Description

The CS5330A / 31A is a complete stereo analog-todigital 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 between 2 and 50 kHz.The CS5330A / 31A operates from a single +5V supply and requires only 150 mW for normal operation, making it ideal for battery-powered applications.

The ADC uses delta-sigma modulation with 128X oversampling,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 stopband rejection. The device also contains a high pass filter to remove DC offsets.
CS5330A is available in a 0.208" wide, 8-pin surface mount package.
