Six/Two Channel, 104 dB Codec with Mux and PGA
The CS4245 is a highly integrated stereo audio codec an integrated analog input selector on the front end to accommodate up to six stereo audio sources. Also included is a programmable gain amplifier (PGA) capable of ±12 dB of analog gain in 0.5 dB step sizes with zero-crossing, click-free transitions to maintain sonic quality. One pair of inputs has a dedicated microphone pre-amplifier in its path that provides 32 dB of gain, and a low noise microphone bias supply is also available. The D/A converter includes digital attenuation, single ended inputs and outputs, and Popguard® technology for control of clicks and pops.
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.
