High noise immunity operational amplifier analog switch It uses theanalog electronic switching to replace contact switch, and itcan prevent sparkle and radio interference. The diagram is the circuit using junction field effect transistor and operational amplifier and its equivalent machiinery track. When input signal UE ( or UE1, UE2...) has control signal ( high level 10V) , junction field effect transistor is breakover, and it output signal UA ( anti-phase)through operational amplifier. Diagram shows the similar circuit.
