4. BTL Driver(Except for Tray Motor Driver)
The voltage, V
REF
, is the reference voltage given by the bias voltage of the pin 23. It can be reduced
the total gain of BTL drive part, use additional series resistor into the input pin (pin3,10,19,25). It can
also increase or decrease the voltage gain of the CH1,CH4 using adjustable pin (pin4,24) by inserting
an external series resistor.
