The OPA501 is a high output current operational amplifier. It can be used in virtually all common op amp circuits, yet is capable of output currents up to 10A. Power supply voltages up to 40V allow very high output power for driving motors or other electromechanical loads. Safe operating area is fully specified, and user-set current limits provide protection for both the amplifier and load. The class-B (zero output stage bias) provides low quiescent current during small-signal conditions. This rugged hybrid integrated circuit is packaged in a metal 8-pin TO-3 package. Both industrial and military temperature range models are available.
