OPA549S

产品概述

The OPA549S is a single 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 input common-mode range extends below the negative supply. The OPA549 is internally protected against over-temperature conditions and current overloads. In addition, the OPA549 provides an accurate, user-selected current limit. Unlike other designs which use a power resistor in series with the output current path, the OPA549 senses the load indirectly. This allows the current limit to be adjusted from 0 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.
