If you have 8 analog input sensors (or 2 or 9 or 738479) is there a chip / is it possible with microprocessor programming to actively monitor all of the channels? Say you had 8 rotary potentiometers ...
I'm having problems using HEF4051 as an analog mux. I'm using it to switch between different audio toslink signals. Right now I'm only testing it with one signal and it works for 1-2 seconds when I ...
I already know how to extend the number of digital pins on an Arduino using a multiplexer. I want to increase the number of analog input channels that I have. One solution is to add another Arduino ...
I have a digital potentiometer that I want to calibrate by sending in my commands and then measuring what the actual resistance is. However, the resistance from the digital pot is (obviously) ...
What (if any) difference is there between mux/demux IC's and analog switch IC's? I'm comparing this in the context of chips with the same IO lines (for example a 1:2 or 2:1 mux/demux vs. a SPDT ...
I need to read several analog sensors on a Arduino Mega ADK. I want to use a multiplexer for this (CD74HC4067E), see the schematics. The output however from the multiplexer channels is not ...
I have a side-project to read temperatures from 4 thermocouples (K type, around 500F for coffee roaster data logger), and no previous analog experience at these levels. I've identified two possible ...
Quick general summary: In analog time division multiplexing, after combining several continuous signals into a single line, do you generally need to use some form of sample and hold to reconstruct ...
Does anyone know some ref of high voltage high bandwidth analog multiplexer? I am looking for a mux that can tolerate input voltages up to 10V, but has also a high bandwidth of at least 1Ghz. I am not ...
