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.
