LA74310LP Overview
Monolithic Linear IC LA74310LP Overview Audio Interface for DSC + Video Driver The LA74310LP is an AV interface IC for digital still cameras (DSCs). It incorporates all the functions necessary for analog audio signal processing for microphone and loudspeaker amplifiers. It also incorporates video output drivers that require no output coupling capacity.
LA74310LP Key Features
