Ordering number EN 5189 Monolithic Linear IC LA9230M/9231M Analog Signal Processor (ASP) for CD players Overview Package Dimensions unit mm The LA9230M and LA9231M are analog signal processing and servo control bipolar ICs designed for use in compact disc 3159-QIP64E players; a compact disc player can be configured by combining these ICs, a CD-DSP such as the LC78620E, and a small [LA9230M/9231M] number of additional components. The differences between the LA9230M and the LA9231M are that the LA9231M (1) has a focus search time that is four times faster; (2) has an additional capacitor pin for focus search smoothing; (3) and can disable output of the track-kick signal during EF balance adjustment.
