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 electro-
mechanical 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 mili-
tary temperature range models are available.
