GA3216 - ON Semiconductor

GA3216 Pre-configured DSP System

The Foundation GA3216 hybrid is a trimmer−configurable DSP system based on a two−channel compression circuit. It can efficiently replace traditional hearing−aid compression circuits without compromising fundamental performance requirements. A trimmer interface supports manual circuit configuration. It continuously monitors trimmer positions and translates th.
