98 dB, 96 kHz, Low Power Stereo A/D Converters

The cost effective CS5343/44 perform sampling, A/D conversion and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 108 kHz per channel and deliver 98 dB of dynamic range and -92 db of THD + N. They differ only in serial audio interface format support, with the CS5343 supporting the I²S format and the CS5344 supporting left-justified serial data format.
