Description
The OPA549T is a low-cost, high-voltage/high-current operational amplifier ideal for driving a wide variety of loads. This laser-trimmed monolithic integrated circuit provides excellent low-level signal accuracy and high output voltage and current.
The OPA549T operates from either single or dual supplies for design flexibility. The input common-mode range extends below the negative supply.
The OPA549T is internally protected against over-temperature conditions and current overloads. In addition, the OPA549T provides an accurate, user-selected current limit. Unlike other designs which use a "power" resistor in series with the output current path, the OPA549T senses the load indirectly. This allows the current limit to be adjusted from 0A to 10A with a resistor/potentiometer, or controlled digitally with a voltage-out or current-out Digital-to-Analog Converter (DAC).
The Enable/Status (E/S) pin provides two functions. It can be monitored to determine if the device is in thermal shutdown, and it can be forced low to disable the output stage and effectively disconnect the load.
The OPA549T is available in an 11-lead power package. Its copper tab allows easy mounting to a heat sink for excellent thermal performance. Operation is specified over the extended industrial temperature range, –40°C to +85°C.
