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 69 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.
