OPA541
OPA541
DESCRIPTION
The OPA541 is a power operational amplifier capable
of operation from power supplies up to
±
40V and
delivering continuous output currents up to 5A. Inter-
nal current limit circuitry can be user-programmed
with a single external resistor, protecting the amplifier
and load from fault conditions. The OPA541 is fabri-
cated using a proprietary bipolar/FET process.
Pinout is compatible with popular hybrid power am-
plifiers such as the OPA511, OPA512 and the 3573.

PACKAGES
The OPA541 uses a single current-limit resistor to set
both the positive and negative current limits. Applica-
tions currently using hybrid power amplifiers requir-
ing two current-limit resistors need not be modified.
The OPA541 is available in an 11-pin power plastic
package and an industry-standard 8-pin TO-3 her-
metic package. The power plastic package has a cop-
per-lead frame to maximize heat transfer. The TO-3
package is isolated from all circuitry, allowing it to be
mounted directly to a heat sink without special insula-
tors.
