DESCRIPTION
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.

NOTES: (1) Package must be derated based on a junction-to-case thermal resistance of 2.2°C/W or a junction-to-ambient thermal resistance of 30°C/W. (2) Safe Operating Area and Power Derating Curves must be observed. (3) With ±RSC = 0. Peak output current is typically greater than 10A if duty cycle and pulse width limitations are observed. Output current greater than 10A is not guaranteed.
