... Ordering number : EN5652 Overview The LA2650 is a bass boost IC developed for use in mini- component stereo systems, TV sets, and radio/cassette player products. The cutoff frequency is determined by external capacitors, and the boost gain, addition level, and boost on/off state can be controlled by a microcontroller. ...
