Although simple brute-force paralleling of op-amps is a bad scheme for driving heavy loads， here is a good scheme for dual op-amps. It is fairly efficient， and will not overheat if the load is disconnected. It is not useful for driving active loads or nonlinear loads， however. In Figure 1， an LF353N mini-DIP can drive a 600X load to g9V typical （g6V min guaranteed） and will have only a 47§C temperature rise above free air. If the load R is removed， the chip temperature will rise to a50§C above free air. Note that A2’s task is to drive half of the load. A1 couldbe applied as a unity-gain follower or inverter， or as a highgain or low-gain amplifier， integrator， etc. While Figure 1 is suitable for sharing a load between 2 amplifiers， it is not suitable for 4 or more amplifiers， because the circuit would tend to go out of control and overheat if the load is disconnected. Instead， Figure 2 is generally recommended， as it is capable of driving large output currents into resistive， reactive， nonlinear， passive， or active loads. It is easily expandable to use as many as 2 or 4 or 8 or 20 or more op-amps， for driving heavier loads.
