The CS5331A is a complete stereo analog-to-digital converter that 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 kHz and 50 kHz.The CS5331A operates from a single +5 V 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.The device is available in an 8-pin SOIC package in both Commercial (-10° to +70° C) and Automotive grades (-40° to +85° C).
