the op-amp analog switch with high anti-interference ability circuit

Published:2011/6/21 1:35:00 Author:Fiona | Keyword: the op-amp analog switch, high anti-interference ability | From:SeekIC

The circuit uses analog electronic switches to replace the node switch to prevent sparking and radio-frequency interference.The picture shows the circuit using junction field-effect transistor and operational amplifier and its equivalent mechanical lines.When the input signal UE (UE1, UE2) has control signal (high 10V) in the B side,the junction field-effect transistor conducts, produces the output signal UA through the operational amplifier. The picture is shown a similar circuit.
