The LA9230M and LA9231M are analog signal processing and servo control bipolar ICs designed for use in compact disc players; a compact disc player can be configured by combining these ICs, a CD-DSP such as the LC78620E, and a small 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.
