Simple High Impedance DC Voltmeter Using a uA741 Op-amp


Posted on Feb 6, 2014

Circuit diagram of this simple in design for high voltage DC Impedance. This is a circuit diagram with circuit design that was built by uA741 IC. IC is the op-amp non-inverting DC amplifier. IC that has a negative feedback through the DC meters need to 1mA full-scale deflection. Working principle of this circuit is a circuit since R6 is 100 ohms, the meter will indicate full scale when the input voltage DC to pin3 is the same as the voltage drop at R6, which is 0.1 volts
