TS3A5017-Q1: Multiplexing AC Signal

You can use any analog multiplexer that supports the desired bandwidth and voltage range.

The TS3A5017-Q1 supports only voltages between GND and 3.6 V. If your signal goes below GND, then you need a switch that supports dual supplies ("Power supply voltage - dual" in the search function), or a switch that has the "Supports negative voltages" feature.

Hello Amit 

I agree with Clemens on this 

1. If you want to use a dual supply mux the TMUX4052-Q1 can be an option as it can be used in a +/-5v supply and pass any signal between that range.

2. If you want to use a device that "Supports negative voltages"  with a single supply you can use the tmux2889. This device is a 2:1 2channel device instead which is different than the configuration for your original device and is not an automotive device.

Do you need an automotive device?

Please let me know

Hi Clemens , Thanks for your reply

Hi Kameron, Thank you for your reply. 

My intended use is not automotive. Also since i have to multiplex more than one AC signals can I use TMUX7348FPWR for low voltage AC signal input ( 500mV).  One more thing , if i have to use more than one tmux2889 can i use Vdd pins of tmux2889 ICs as a simple multiplexer enable switch ( A0, A1, A2...).. What i mean to say that if i made Vdd =0 on continuous basis for device selection , will it have any negative impact on device itself.

I have to multiplex 6 AC signals....

What available supplies are there?

The TMUX2889 behaves like an open switch when powered off.

Hi Clemens.

+5V and +3.3 V is available. I can modify the design to accommodate -5V supply also. I am going to implement the Multiplexing solution using MUX4051 and MUX36D08IRSNR,  as i don't know switching VDD of tmux2889  on and off on regular intervals will be a better design practice... Kindly tell  me if i am wrong somewhere..
