Analog Switch Schematic. As the frequency increases an increasing amount of signal reaches the output. Each switch has an enable pin a and two input output pins x and y.
1 sig a in out i o input output for switch a 2 sig a out in i o output input for switch a 3 sig b out in i o output input for switch b 4 sig b in out i o input output for switch b 5 control b i control pin for switch b 6 control c i control pin for switch c 7 vss low voltage power pin 8 sig c in out i o input output for switch c. Cmos analog switches perform best when the output is terminated at a reasonably low impedance. The signal can flow in either direction between the two pins of each switch.
Try measuring the ron vs input voltage for other cmos analog switches such as the cd4016 cd4066 quad switches or the cd4051 cd4052 and cd4053 analog multiplexers or the adg419 spdt analog switch or adg333 quad spdt switch.
Analog switch schematics circuits. The 4066 is an ic composed of switches which are designed to switch analog signals via digital control. The 4066 really functions as an analog switch. 1 sig a in out i o input output for switch a 2 sig a out in i o output input for switch a 3 sig b out in i o output input for switch b 4 sig b in out i o input output for switch b 5 control b i control pin for switch b 6 control c i control pin for switch c 7 vss low voltage power pin 8 sig c in out i o input output for switch c.
