16bit Stereo Audio CODEC with Loud Sound and Audio Enhancement for microphone
Description
ML26121AHB/ML26121AGD is 16bit stereo audio codec with some sound effect technologies naturally reproduces low band which is removed together wind-noize reduction and 3D surround technology to enable realistic stereo sound even when microphones are closely laid out and LoudSound technology to output louder and higher-quality sound even with a small speaker.
By combining LAPIS Semiconductor's unique technologies of analog circuit design for ultra small-size and wafer-level chip-size packaging (W-CSP), LAPIS Semiconductor succeeded in developing an LSI with dimentions of 2.96mm x 2.96mm, the smallest package size in the world.
ML26121A is the most suited stereo CODEC for a stereo type portable device because of its characteristic acoustic treatment and compact package.
ML26121AHB is 34pin WCSP package; ML26121AGD is 36pin WQFN package.
