OPA549 Module Voltage Controlled Constant Current Source Constant Voltage Source AC Current Source High Voltage High Current VI Conversion Motor Drive (Constant Voltage Mode) -83840

Special attention should be paid to driving inductive or large capacitive loads such as motors or coils, and it is necessary to add a protective circuit by itself to avoid instantaneous changes in back electromotive force from damaging the module.

The heat sink and the chip are in direct contact with live electricity, do not touch other power sources or short-circuit them.

OPA549 is a low-cost, high-voltage/high-current operational amplifier, which is very suitable for driving various loads. This laser trimmed monolithic integrated circuit provides excellent low-level signal accuracy and high output voltage and current.

OPA549 module adopts dual power supply by default, OPA549 has internal overheating protection function conditions and current overload. In addition, OPA549 provides accurate, user-selectable current limit. Unlike other uses of "power" resistors and output current paths, OPA549 indirectly detects the load. It is suitable for motor drive speaker drive, transformer drive and audio amplifier, etc. It can also amplify triangle wave, sine wave, and square wave signals.
