Description
AI
The OPA548 device is a low-cost, high-voltage, and high-current operational amplifier that is designed to drive a wide variety of loads. A laser-trimmed, monolithic, integrated circuit provides excellent low-level signal accuracy and high-output voltage and current.
The OPA548 operates from either single or dual supplies for design flexibility. In single-supply operation, the input common-mode range extends below ground.
The OPA548 is internally protected against overtemperature conditions and current overloads. In addition, the OPA548 is designed to provide an accurate, user-selected current limit. Unlike other designs that use apowerresistor in series with the output current path, the OPA548 senses the load indirectly. The current limit is adjustable from 0 A to 5 A with an external resistor and potentiometer, or controllable 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 OPA548 is in thermal shutdown.
The OPA548 device 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. The device is specified for operation over the extended industrial temperature range, –40°C to 85°C. A SPICE macromodel is available for design analysis.
