Product Descriptions

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 lowlevel signal accuracy and high-output voltage 

andcurrent.

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 a power resistor in series with the 

output current path, the OPA548 senses the load indirectly. The current limit is adjustable from 0 A to 5A 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 industrystandard 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.
