3 Description

The OPA541 device is a power-operational amplifier

capable of operation from power supplies up to ±40 V, and delivering continuous output currents up

to 5 A. Internal current-limit circuitry can be user•

programmed with a single external resistor, protecting

the amplifier and load from fault conditions. The OPA541 devices fabricated are using a proprietary

bipolar and FET process.

The OPA541 uses a single current-limit resistor to set both the positive and negative current limits.

Applications currently using hybrid power amplifiers

requiring two current-limit resistors do need not to be

modified.

The OPA541 is available in an 11-pin power plastic

package and an industry-standard 8-pin TO-3 hermetic package. The power plastic pachage has a

copper-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

insulators.
