Also there is the AD instrumentation amplifier which is again, single-channel but is great if you want to programmatically amplify your signal in the analog zone, not losing your dynamic range.
But my design requires 4 or 8 analog inputs. I had some research on the internet for comparison of MUXes. From the noise aspect in Communications Circuits Engineering, the equivalent thermal noise introduced on the signal could be equivalent to sqrt 4 K T R B.
But is that all the noisy source? Other people have also had the same question but in other senses, such as: How much is the noise of a multiplexer for analog inputs? The question is: Is my discrete analog MUX solution a big deal from the signal integrity and noise aspect?
Did anyone have these problems with Various - Au Revoir Alastair same approach? If it is really a bad idea, what would be other ways of solving this issue? Is my discrete analog MUX solution a big deal from the signal integrity and noise aspect? It's not a bad idea because for instance you only need one instrumentation amplifier with high gain to amplify your small signal of 1 mV but the problem comes with the output impedance of your small signal and the input capacitance of the instrumentation amplifer.
Just as a guessed example let's say the input capacitance is 10 pF; for this to Analog - Reznyk - First Stage the full potential of the input you need to "sample" for significantly longer than 5 x CR i. Like I said you need significantly better than this to charge the capacitor to get an accurate reading.
So maybe you have to "dwell" on each channel for us. If you had two channels you have effectively us sampling time and Analog - Reznyk - First Stage means the highest frequency you can resolve due to nyquist et al is Hz and probably it'll be closer to 2 kHz. So immediately you hit a problem with Analog - Reznyk - First Stage multiplexer and I would advise you either buffer each signal to give it a low impedance then feed the multiplexer. In fact the same problem will arise with most common ADCs that contain a multiplexer so my advice is do some more reasearch.
I might add that I have designed a similar system for measuring thermocouples i. However, it does prove the point that noise needn't be an issue using an external multiplexer. Home Questions Tags Users Unanswered.

Go to digikey. I have to correct my earlier saying. I have one or two AD in my lab and almost always I We Are The Champions - Queen - Hungarian Rhapsody (Live In Budapest) (Blu-ray-R, Album) something cheaper that does the job equally well if not better. And since you care about the price, I just wanted to point that out. What about an AD or similar?
But in my case I must Analog - Reznyk - First Stage make sure that I can find those in my country's market. Otherwise I have to import. Andy aka Andy aka k 12 12 gold badges silver badges bronze badges.
