Description

The OPA548 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 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, it 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 device senses the load indirectly. This allows the current limit to be adjusted from 0 to 5A 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 it is in thermal shutdown.

The OPA548 is available in an industry-standard 7-lead staggered 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, 40 to +85. A SPICE macromodel is available for design analysis.
