The OPA547T-1 is a 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 OPA547 operates from either single or dual supplies for design flexibility. In single-supply operation, the input common-mode range extends below ground. The OPA547 is internally protected against over-temperature conditions and current overloads. In addition, the OPA547 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 OPA547 senses the load indirectly. This allows the current limit to be adjusted from 0 to 750mA with a 0 to 150μA control signal. This is easily done with a resistor/potentiometer or controlled digitally with a voltage-out or current-out DAC. The enable/status (E/S) pin provides two functions.
- Wide output voltage swing
- Fully protected - Thermal shutdown and adjustable current limit
- Output disable control
- Thermal shutdown indicator
- Low quiescent current
- 500mA Continuous high output current
- Green product and no Sb/Br
