SANYO LA9605W

Ordering number : EN5980
Monolithic Linear IC
LA9605W
MD Player RF and Matrix Signal-Processing IC
Overview
Package Dimensions
The LA9605W integrates MiniDisk playback functions,
including servo error signal generation, RF signal
processing, and wobble signal binarization output on a
single chip. The LA9605W, when combined with an
LC89640, can implement a complete MD player system.
