Related Hardware and Initiatives. 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.

This is so because 1mA is passing through the 1st MUX. I am interested in developing a generic 8-channel 4-wire PT interface for RaspberryPi.

Arduino Playground –

Board Setup and Configuration. A multiplexer or demultiplexer enables you to expand the in-and outputs on your Arduino board. Needed accuracy must be better than 1degC and range from degC.

There is no such limit on switch current- 1uA is leakage. Additionally i need lead wire compensation. Does dztasheet make sense? But this increases components and board size.

This circuit lacks protections and needs to be completed as many pins are yet open, but at the least the basic scheme must be verified.

I guess i will have to go with the better versions of for now. However the high on datasgeet will dataaheet prevent you from reaching the required accuracy.

I have also included a resistance 2. I did not think about voltage compliance with A0. Since it expands i cant post it as a comment. If any errors or possible limitations please do let me know.

Spehro Pefhany k 4 One can look at the schematic and explanations here. This i presume will help make a better differential measurement at the ADC A2 and A3 while avoiding any current passage through HC But you can read and write cf4051 the pins quite fast.

The last HC has no use because all the inputs are shorted common to the exit resistor!

I xd4051 with local supplier and they dont have this available. What is possible is to use a current source for each sensor and then only multiplexing the resulting voltage to the ADC input.

If you use the as a Multiplexer: 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.

If you use the as a Multiplexer: Arduino on other Chips. If some other idea could be evolved, it would be great! You can choose between 8 different inputs and select just one you want to read at the time. Am i wrong or OK in this regard?

Here is the plan: I will hand pick the resistors but what about temperature compensation? In this figure, the first wire of pt is supplied by 1mA current through a HC see footnote.

It may affect the actual current. Bimpelrekkie One current source for each pt is a good idea, thanks. Each of these pins have to be connected to one digital out pin on the Arduino. Sign up using Email and Password. Yes, you can do that perhaps not with the CD and perhaps not with that particular 1mA current source, because of voltage compliancehowever the only point of ADC input A0 is to check that the current source is not outside compliance voltage.

The multiplexers would then be switched to the same input at the same time. The playground is a publicly-editable wiki about Arduino.
