Rotational direction control
The forward and reverse rotational direction is controlled by FWD (pin16) and REV (pin17) and the input conditions are as
follows;

=8V)
- The maximum torque is obtained when the pin15(CTL) is open.
- If the voltage of the pin15 (CTL) is 0V, the motor will not operate.
- When the control voltage (pin15) is between 0 and 3.25V, the differential output voltage V(out1,out2) is about two times
of control voltage. The output gain is 6dB.
- When the control voltage is greater than 3.25V, the output voltage is saturated at the 6.5V because of the output swing
limitation.
