5. Focus, Tracking Actuator, Spindle, Sled Motor Drive Part
The Vref at pin 43 is for eliminating the dc components from the input signals and can set by an exteranl circuit.
The voltage gain from Vin to output is as follows ;
Where
V means just ac component.
The total input to output voltage gain is the sum of the input OP amp network gain and 18dB.
The output stage is the balanced transformerless (BTL) driver.
The bias voltage Vp is expressed as ;
