hi logic control voltage i will give 1.8 volts input signal i will drive +/- 12 v this will work. TMUX6201 ac/dc both

i used SPST relay previous circuit now i don't want relay can i use TMUX6201 switch

The TMUX6201 will also work with 1.8 V control signals and 24 V I/O signals

A relay would allow galvanic isolation, i.e., different or floating ground voltages. I do not know if you need that.

Hello Shivaraj,

I agree with Clemens and the TMUX6201 is a good replacement for the relay you previously used in your circuit. It can suppourt 1.8V logic and you can pass +/- 12 v ac or dc signals through the device.

While relays do have a advantage in galvanic isolation, Ti multiplexers Flat ron can provide a more optimized solution than relays

Check out this app note that talks more about replacing relays with multiplexers.

Please let me know if you have any questions

data sheet mentioned +/- 4.5 in my application sending signal low -7 V sine wave peak to peak & high signal 12 volts max for this application i am finding spst Relay
