It is more than likely something I am doing wrong which I haven’t understood from the datasheet. Your gain is affected by the tolerance of these resistors. Just saying hello Started by MichaelaJoy Yesterday at 6: I have attached the test circuit and tabulated the results.

Use the builtin linear and logarithmic sweep function, supporting up dafasheet sweep points, to. Hi, Managed to get things seemingly working ok.

Thanks for the reply.

Potentiometer Questions Started by norbss Yesterday at The online electronic component datasheets search engine. Jul 1, 24 0. I initially applied a 50mV output offset as per figure 6 and immediately got results more accurate than I could measure with my cheapo multimeter.

Replacing a 4 pin leaded inductor with a 2 pin Lna326 by gkmaia Yesterday at I was suggesting to eliminate the pot just for testing. Also, any resistors above Ona326 can be problematic if they get dirty or wet. Ideally, the inverting terminals will have the same voltage as their noninverting counterparts.

Welcome to our site! The inputs are really rail-to-rail, and the outputs are within a few millivolts of each rail.

Hi, I included the pots, in particular the Vin- and gain pots because I intend to have them in the final circuit for voltage translation and gain adjust. That way, you know you have an overall gain of 2. Rail-to-rail on either ins or outs is a problem with instrumentation amps, especially with a single supply.


Help Posted by Gashi in forum: From figure 5, pg 12 of the ina datasheet like the example inamp discussed before, the input signals of the ina go to the datasheey inputs of the first stage of the inamp. I hope this helps. To make sure it’s not that non-linearity that causes any problems you could use the setup in figure 6 to introduce an offset into the output voltage.

As my test results stand, the linearity is way off the suggested specifications so something is seriously amiss and I have yet to understand why As devicedocumentation issues become known to us, we will publish an errata sheet. On the pin 5, I connect k resistor and 0,1uF datxsheet. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

What can be problem? Figure 6 suggest mV offset voltage and I will go with this for ‘safety’ and practical reasons as this requires use of a 10M resistor.

Given that this mention is virtually hidden and the fact that I would imagine most applications would require measurement near zero as I do seems to suggest to me that the datasheet is saying that not having an offset would not really affect linearity.
