Adjustable Current Source – 0 to 1A

https://www.electronics-lab.com/project/adjustable-current-source-0-to-1a/

  This voltage-to-current (V-I) converter delivers a well-regulated current to a load. The circuit accepts an adjustable input voltage from Trimmer potentiometer PR1 and converts it to an output current from 0A to 1A. The current is regulated by feeding the voltage across a low-side, current-sense resistor R9 back to the OPAMP. The output Darlington […]
