The OPA541AM is a single high power monolithic Operational Amplifier capable of operation from power supplies up to ±40V and delivering continuous output currents up to 5A. Internal current-limit circuitry can be user-programmed with a single external resistor, protecting the amplifier and load from fault conditions. The OPA541 device fabricated is 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.
