1 / 20 page  Analog Signal Processor (ASP) for CD players Overview 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. Functions I/V amplifier, RF amplifier (with AGC), SLC, APC, FE, TE (with VCA and auto-balance function), focus servo amplifier (with offset cancellation 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 Package Dimensions unit : mm 3159-QIP64E [LA9230M/9231M] SANYO : QIP64E Specifications Maximum Ratings at Ta=25 °C, Pins 22, 45 = GND Parameter Symbol Conditions Ratings Unit Maximum supply voltage Vsup max Pin 56, 64 7 V Allowable power dissipation Pd max 350 mW Operating temperature Topr –25 to +75 °C Storage temperature Tstg –40 to +150 °C Ordering number: EN 5189 Monolithic Linear IC LA9230M/9231M SANYO Electric Co.,Ltd.
