Overview
The LC89602 is an audio decoder LSI for mini-disk playback units. This LSI implements the processing that precedes the D/A converter in playback-only mini-disk players. That is, the LC89602 receives data in sound frame units from a mini-disk data decoder LSI (such as the Sanyo LC89610), expands the audio signal and decoder that signal directly to a D/A converter.
