Simple voltage value comparison circuit

Probe current voltage pin 420*4450 head diameter 5.0 over current current and voltage pin

TP-IP4220CZ6 5V 0.35PF breakdown voltage 6V SOT

Shunuo varistor / ESD varistor / product complete / Sunlord first-class agent

Industrial Router Crystal 3.2*2.5mm 3225 26M (26.000MHZ) 12PF 10PPM 20PPM 30PPM

This circuit uses a comparator, the input negative terminal is fully connected to Ui, the positive terminal gives different potentials through the resistance value, and compared with the input voltage Ui, the input voltage Ui is judged according to the number of LED illuminations. The more the number of LEDs is illuminated, the smaller the input voltage Ui is.
