16bit Stereo Audio CODEC with Loud Sound and Audio Enhancement for microphone
Description
ML26121A 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 OKI SEMICONDUCTOR's unique technologies of analog circuit design for ultra small-size and wafer-level chip-size packaging (W-CSP), OKI 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.
