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.
