Features, Applications

The is a complete analog-to-digital converter for stereo digital audio systems. It performs sampling, analog-to-digital conversion and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form. The output sample rate can to 50 kHz per channel. The CS5394 uses 7th-order, delta-sigma modulation with 64× oversampling followed by digital filtering and decimation, which removes the need for an external antialias filter. The ADC uses a differential architecture which provides excellent noise rejection. The CS5394 has a linear phase filter with passband to 22.1 kHz, 0.005 dB passband ripple and >117 dB stopband rejection. The CS5394 is targeted for the highest performance professional audio systems requiring wide dynamic range, negligible distortion and low noise. ORDERING INFORMATION C CDB5394
