Monolithic Linear IC
LA9220M
Analog Signal Processor Circuit (ASP) for CD Players
Overview
The LA9220M is an analog signal processing and servo control bipolar IC designed for use in compact disc players ; a compact disc player can be configured by combining this IC, a CD-DSP such as the LC78681KE, and a small number of additional components.
Functions
I/V amplifier, RF amplifier (with AGC), SLC, APC, VCOC amplifier, VCO (supports double-speed playback), FE, TE (with VCA and auto-balance function), tracking servo amplifier (with offset cancellation function), spindle servo amplifier (with gain switching function), sled servo amplifier (with off function), focus detection (DRF, FZD), track detection (HFL, TES), defect detection, and shock detection.
Features
The following automatic adjustment functions are built in. Focus offset auto cancel. Tracking offset auto cancel. EF balance auto adjustment. RF level AGC function. Tracking servo gain RF level following function.
