The fundamental concept of load sharing is to drive a load using two or more of the same operational amplifiers. Each amplifier is driven by the same source. Figure 9-1 illustrates the schematic for this design. This concept effectively reduces the current load of each amplifier by 1/N, where N is the number of amplifiers. For further details on the design and performance of this circuit, see the Reference Design for Implementation of the Load Sharing Concept for Large-Signal Applications.
