LC89602 Audio Decoder LSI

Ordering number : EN 5059A CMOS LSI LC89602 Audio Decoder LSI for Mini-Disk Playback Preliminary 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. This audio expander LS.

LC89602 Features

* Stereo audio expansion implemented in a single chip

* High-precision arithmetic using a 24-bit multiplier

* Expanded dynamic range provided by a block floatingpoint circuit

* Two output systems and independent attenuators built in

* Digital audio outputs wit
