1) Two comparators built-in:Two general-purpose voltage open collectoroutput comparators are built-in.2) Two channels are voltage-type BTL driversactuators of tracking and focus. Two channelsvoltage-type BTL driver for sled and spindlemotors. It is also built-in one channel bi-directionDC motor driver for tray.3) Wide dynamic range [9.0V (typ.) when Vcc1=Vcc2= 12V, at RL= 20 load].4) Separating power of Vcc1 and Vcc2 isimprove power efficiency by a low supplyvoltage for tracking, focus, and spindle.5) Level shift circuit built-in.6) Thermal shut down circuit built-in.7) Mute mode built-in.8) Dual actuator drivers:A general purpose input OP provides differentialinput for signal addition. The output structure istwo power OPAMPS in bridge configuration.9) Sled motor driver:A general purpose input OP provides differentialinput for signal addition. The output structure isone power OPAMP in bridge configuration.10) Spindle driver:Single input linear BTL driver. The outputstructure are two power OPAMPS in bridgeconfiguration.11) Tray in-out driver:The DC motor driver supports forward/reversecontrol for tray motor.
