q Loading channel

The loading channel is the circuit of BTL voltage drive. This circuit

has the referential input. Output swing is determined with ∆Vin X 8.

Also,it is possible for this channel to use for the slide motor , the

focus coil and the tracking coil.

The input terminal is high impedance. It is possible to do variable a

gain by external resistor.

In case of one MCU port, if use three state port, it is possible for

this channel to have the stop function.
