4 Conclusion

A practical design for an OPA593 device in a Leader-follower parallel output configuration was developed and tested with good results. The circuit is applicable to numerous component test and analog power applications. Special attention was made to balancing the output current load shared between the two OPA593 high-voltage, high-current op amps. The circuit readily delivered a 0.5-A output current to a 100 Ω load. Particular attention was paid to compensating the amplifier circuit so that it could readily drive a high-capacitance 1-µF load. The OPA593 parallel output amplifier maintained complete stability for all output loads tested.
