8.4.3 Parallel mode

In Parallel mode; the two output stages operate in parallel to enlarge the drive capability.

The inputs and outputs for Parallel mode must be connected on the Printed-Circuit Board

(PCB) as shown in Figure 14. The parallel connection can be made after the output filter,

as shown in Figure 14 or directly to the device output pins.
