Highlights: The module is an audio power amplifier with high voltage and high current. It can output 8A current continuously with a peak value of 10A. It can ideally drive various loads, such as motor drive, horn drive, transformer drive and audio amplifier. It can also amplify triangular, sinusoidal and square wave signals. Details: OPA549 is a low-cost, high-voltage, high-current operational amplifier, which can ideally drive various loads. This laser trimming monolithic integrated circuit provides excellent accuracy of low level signals and high output voltage and current. The flexibility of OPA549 design supports single or dual power operation. Input Common Mode Range Extension Lower than Negative Power Supply OPA549 has internal temperature and current overload protection. In addition, OPA549 provides accurate, user-selectable current limits. Unlike other "power" resistors connected in series with the output channel, OPA549 indirectly senses the load. This allows it to perform current limitation from 0 A to 10 A through a resistor/potentiometer, or to perform digital control through a voltage or current output digital-to-analog converter (DAC). The enable/state (</S) pin provides two functions. It can be monitored to determine whether the device is in thermal shutdown and can force a low disabled output stage and effectively disconnect the load. 0PA549 is an 11-ead power turn-off. Its label can be easily mounted on the radiator because of its excellent thermal performance. As specified in the extended industrial temperature range, 40 °C to 85 °C.
