Echo and delay
CD2399 is a digital echo / delay processor with the PT2399 function; M65831 is an echo processor for microphones in karaoke systems.
Volume and audio processing
M62429 and M62429L are serial-controlled dual electronic volume ICs. CD3314 / CD3314LE are 4-channel-input audio processors.
Power amplifiers
AiP8002 (2 W mono), CS4871 (3 W mono with shutdown), CS4863 (dual 2.2 W with stereo headphone function) and AiP9971 (5 W, class-AB / class-D selectable) cover portable speakers and small consumer devices. Check output power against supply voltage and load in each datasheet.
