DESCRIPTION
The OPA502 is a high output current operational
amplifier designed to drive a wide range of resistive
and reactive loads. Its complementary class A/B
output stage provides superior performance in
applications requiring freedom from crossover distor-
tion. Resistor-programmable current limits provide
protection for both the amplifier and the load during
abnormal operating conditions. An adjustable foldover
current limit can also be used to protect against
potentially damaging conditions.
The OPA502 employs a custom monolithic op amp/
driver circuit and rugged complementary output
transistors, providing excellent DC and dynamic
performance.
The industry-standard 8-pin TO-3 package is electri-
cally isolated from all circuitry. This allows the
OPA502 to be mounted directly to a heat sink without
cumbersome insulating hardware which degrade
thermal performance. The OPA502 is available in
–40°C to +85°C temperature range.
