HT8665, Talking Back

The HT8665 is a single chip CMOS LSI using an ADM algorithm.

It is designed for applications on talking back with an echo effect.

Functions of the IC consist of recording/playing and auto power off in addition to an echo effect.

The IC starts recording when a sound input is detected, and stops to pl
