General Description The HT8665 is a single chip CMOS LSI using an ADM algorithm. It is designed for applica- tions on talking back with an echo effect. Func- tions of the IC consist of recording/playing and auto power offin addition to an echo effect. The IC starts recording when a sound input is de- tected, and stops to play back when silence lasts 0.5 seconds during recording. The auto power off function is activated once a REC/PLAY cycle has been implemented 64 times or an interval of silence that exceeds 2 minutes.
