Taidacent Constant Voltage Constant Current OP Amp Operational Amplifier Circuit OPA549 Module for IV to Motor Driver (Constant Voltage Model)

The OPA549 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 combined with high output voltage and current. The OPA549 module is powered by power supply by default, and the OPA549 has an internal function to protect against overheating conditions and current overload. Additionally, the OPA549 provides accurate, user-selectable current limit. Unlike others that use a "power" resistor with the output current path, the OPA549 senses the load indirectly. Suitable for motor drive speaker drive, transformer drive and audio amplifier etc. It can also amplify triangle wave, sine wave, square wave signal.

• Module again Constant current mode Iout = Vin / 1, that is, 1V corresponds to 1A current output. Can To output positive and negative current or current current constant pressure mode The default gain is 22 times, the first level is 2 times, the second level is 3 times, G1=R3/R2+1, G2=R13/R12+1 The first stage is solderable potentiometer to adjust the gain.
