OPA549T Datasheet PDF - TI

The OPA549T is a 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 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 OPA549T 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-analogue Converter (DAC). The enable/status (E/S) pin provides two functions.

● 8A Continuous and 10A peak high output current

● Wide output voltage swing

● Thermal shutdown and adjustable current limit protection

● Output disable control

● Thermal shutdown indicator

● 9V/µs High slew rate

● Control reference pin

● Green product and no Sb/Br

●IC can be damaged by ESD. We recommend that all ICs be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
