The CS5331 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 word rate can be upto 50 kHz per channel.The CS5331 operate from a single +3V or +5V supply and requires only 70 mW for normal operation, making 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 SOIC surface mount package.
