104 dB, Stereo Codec with Mux and S/PDIF Transmitter
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.
Due to circumstances outside of our direct influence, our vendor has given us minimal time to plan within our normal EOL notification period. We ask for your immediate attention to place LTB orders, within the timeline, to allow processing of material and build FG ahead of closure. We have given an extended period for LTS on this occasion due to the difficult circumstances we face. There could be limits to total available material due to time constraints and yields.
