High-Voltage, High-Current Operational Amplifier

The OPA547 is a low-cost, High-Voltage high-current Operational Amplifier ideal for driving a wide variety of loads. A laser-trimmed monolithic integrated circuit provides excellent low-level signal accuracy and high output voltage and current. The OPA547 operates from either single or dual supplies for design flexibility. In single-supply operation, the input common-mode range extends below ground. The OPA547 is internally protected against over-temperature conditions and current overloads. In addition, the OPA547 was designed to provide an accurate, user-selected current limit. Unlike other designs which use a "power" resistor in series with the output current path, the OPA547 senses the load indirectly. This allows the current limit to be adjusted from 0mA to 750mA with a 0 to 150 ??A control signal. This is easily done with a resistor/potentiometer or controlled digitally with a voltage-out or current-out DAC The Enable/Status (E/S) pin provides two functions. An input on the pin not only disables the output stage to effectively disconnect the load, but also reduces the quiescent current to conserve power. The E/S pin output CAN be monitored to determine if the OPA547 is in thermal shutdown. The OPA547 is available in an industry-standard 7-lead staggered and straight lead TO-220 package, and a 7-lead DDPAK surface-mount plastic power package. The copper tab allows easy mounting to a heat sink or circuit board for excellent thermal performance. It is specified for operation over the extended industrial temperature range, 40C to +85C.
