Analog Switches(56)

An Analog Switch IC is an integrated circuit that functions like an electronically controlled relay—it connects or disconnects analog signals (voltage or current) under the control of a digital logic signal.

What Does an Analog Switch Do?

An analog switch acts like a solid-state SPST (Single Pole Single Throw) switch:

• When enabled (logic HIGH): it conducts the analog signal between terminals.

• When disabled (logic LOW): it isolates the terminals (high impedance).

It can pass AC or DC signals, including audio, video, sensor signals, or analog voltage rails.
