Overview
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.

FEATUREs
• Allows the servo error signal level to be set to an arbitrary level using a VCA circuit.
