Opps, I'm sorry, I pasted the wrong page URL. I checked for multiplexers too, they where also expensive.You didn't found any Multiplexer. You found a lot of ADCs, R/D convertors... But any Multiplexers.
It is good to hear, the worst case is that if the signal is distorted or clipped. If the signal is linearly transfered, there is no problem for me.Maybe check the datasheet for that.
They're supposed to exhibit a pretty good transfer characteristic of a resistor. I do know that most have a varying resistance depending on the voltage passed - so as long as they're driving a high impedance device, there should not be any issues.
Great information, thank you very much.Three important characteristics of analog multiplexers to note are: on-resistance, signal amplitude for normal operation, and switching speed. These are noted in the multiplexer data sheet.
I will consider that, thank you.You also need to at least consider parasitic capacitances.
I think I decided to use analog multiplexer instead of an opamp, thank you anyway.Here is an opamp with output disable pin. https://www.electro-tech-online.com/custompdfs/2010/01/LMH6732-1.pdf
You might be able to get a sample from national.
That's too expensive for my project. But one day I may need it for another project. I will keep its datasheet. Thank you.Intersil makes a 4 channel selectable op amp, the **broken link removed**. They are expensive (US $15.76 from Intersil).
You bet!I get the feeling the OP is happy to use an analogue MUX now that he knows they are dirt cheap.
