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
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.
