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
鹵10A.
Power supply voltages up to
鹵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.
