Posted by t23tmx yahoo. Help Posted by Gashi in datawheet The inputs are really rail-to-rail, and the outputs are within a few millivolts of each rail. View tis ina technical documents application notes, more literature, blogs.

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. Use the same part for R2. Rail-to-rail on either ins or outs is a problem with instrumentation amps, especially with a single supply.

Input amplifier for emg measurement is represented by ina 2which is a good choice for portable medical instruments in terms of its small size, low supply voltage, high common mode rejection. I have attached the test circuit and tabulated the results. Unfortunately I don’t seem to be getting the results I was expecting. I was suggesting to eliminate the pot just for testing. So, for my gain, output voltage could be about 1,4V, but when i check voltage with multimeter I see only mV, and when I applied more pressure to my transducer, voltage in the output of amplifier didnt change, still mV.

Sep 11, 7. Leakage current changes the effective resistance. I don’t think it has anything to do with your problem but the output shows some non-linearity near the rail voltage, zero in your case. Your gain is affected by the tolerance of these resistors. What is the unlabeled red wire and what is it connected? Sep 7, 6. Use the AD version.

As devicedocumentation issues become known to us, we will publish an errata sheet. Quote of the day. No, create an account now. Jul 9, 2, 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.

Precision, Low Drift, CMOS Instrumentation Amplifier

Having said that, there is a footnote 3 in figure 1 that suggests for measurements near zero output you will need an output offset. From figure 5, pg 12 of the ina datasheet like the example inamp discussed before, the input signals of the ina go to the noninverting inputs of the first stage of the inamp.

Hi, Datzsheet to get things seemingly working ok.

Ina ina ina ina ina ina ina msop10 text. You May Also Like: I really wanted the full range output of 0V-5V as this is going to be fed into an ADC but I will just have to live with the reduced range.

You’ll also learn how to perform this task via immediate actions or via timers set in advance.
