... DESCRIPTIONS AD6392 is a 4-CH BTL driver suitable for driving mo- tors and actuators in CD-P/VCD-P systems. Each channel drivers except the spindle driver have an internal primary filter and they can be directly con- nected to the servo’s PWM output without any at- tached external components. FEATURES ...
