Calibration equipment Electrical calibration equipment Pressure calibration equipment Temperature calibration equipment. If you use the as dagasheet Multiplexer: In my edit, i made a mistake.

Telecommunication measuring equipment Cable and pipe tracing Cooper networks IT networks Optical networks Spectrum analysers more Do you have a data sheet? Jul 3, 2, The sink of all currents is through a resistor, which i suppose will help in making a noise free measurement. Since no current is flowing, the resistance of mux is not an issue here.

Since it expands i cant post it as a comment.

That gives you a lot of information, especially about maximum voltages. How to use analog hall effect chip of 5v input supply with 24V input supply voltage Posted by Sumit in forum: Sign up or log in Sign up using Google.

If you really want to measure ‘top’ lead resistance for some reason other than break protection for which A0 suffices you can add another analog multiplexer and pick off the voltage at the ‘top’ of the RTD.

A low turns it on and a high turns it off. As long as there is enough voltage headroom across the current source circuit so that it is able to actually make that current flow then any extra series resistance doesn’t matter.


Dec 21, 7. However the high on resistance will still prevent you from reaching the required accuracy. The customer is in the focus We want to make sure that customer is the center of attention.

CD NTE Equivalent NTEB IC-CMOS MULTIPLEXER – Wholesale Electronics

You may be better off expending the scratch for genuine analog switches that have a degree of built in protection and adding some external protection around that. I could order online but it would take weeks and cost a lot import duties to india. Fluke, Mikroelektronika, Knipex and Logitech. In any case, CD voltage drop is excessive at much over 1mA.

Can i use transistors as switchs to route the 1ma instead of CD? Free technical support If something goes wrong, we will be ready and willing to help! Neither can i post as an edit, i guess because it is an answer of sort, a comprehensive one. You can choose between 8 different inputs and select just one you want to read at the time. It is not possible to read or write more than one pin on the at the same time, because you can only select one pin at a time.

Please check the attachment.

What is possible is to use a current source for each sensor and then only multiplexing the resulting voltage to the ADC input. CD maximum analog current Posted by washiloo in forum: Mar 1, A multiplexer or demultiplexer enables you to expand the in-and outputs on your Arduino board.


You aren’t showing cd40051 inputs used for the ‘s, except for the address lines, and they are all connected together. Hi, I shall do that in.

Also i did not yet think about protections to the inputs of the board, a very valid point. Arduino on other Chips. Finally i datxsheet go with the above but a modification using Bimpelrekkie ‘s suggesstions. Can you post the circuit? It may affect the actual current. Spehro Pefhany k 4 Then post your schematic for us to see if it is powered correctly and that the select voltage is high enough.

Here is the plan: Of course, there is no way to measure the resistance of the other two leads because no significant current passes through them. If they are all connected together as it looks like they are, you won’t be able to select individual inputs – or are the address wires supposed to represent an address buss?

Post as a guest Name. Now, when I do not connect the amplifier, I do not see any offset voltage ce4051 it, however, the moment I connect the output if mux to it, the voltage at the input of the amplifier gets offset to around 1. Now could datashset multiplex the input voltages to constant current circuit? That is “electrostatically sensitive”, meaning it can be destroyed by static charges.
