The CS4265 is a stereo audio codec featuring an integrated five-chip design and S/PDIF output to provide premium audio performance. An analog front-end provides a 2:1 input mux and a programmable gain amplifier (PGA) capable of ±12 dB of analog gain in 0.5 dB step sizes with zero-crossing and click-free transitions to maintain superior audio quality. One pair of inputs has a dedicated microphone pre-amplifier in its path to provide 32 dB of gain, and a low noise microphone bias supply is also available. The stereo analog-to-digital (A/D) and digital-to-analog (D/A) conversion is based on multibit Delta Sigma architecture. A synchronous S/PDIF (IEC60958-3) digital audio transmitter is integrated to provide additional design flexibility and to lower system cost.
