10.2 Typical Application

The fundamental concept of load sharing is to drive a load using two or more of the same operational amplifier. Each amplifier is driven by the same source. Figure 10-5 shows two THS3491 amplifiers sharing the same load. This concept effectively reduces the current load of each amplifier by 1/N, where N is the number of amplifiers.
