The problem is that the signal frequency I’m interested in may go ina111 to 1 MHz. Nov 5, 7: I will try to have ina111 PCB made at the university, I will let ina111 know if it works as it should!

To start I would like to verify that you are making connections to the proper pins, because the connections you have described do not align ina111 the pinout of the INA shown below:.

Can you check the attached pdf to see if I got it right?

Ask a related question What is a related ina111 Hello Baptiste, A load cell with a 1MHz ina11 seems extremely high to me. Ina111 figured that I should use a INA with a gain ofwhich should work fine at 1 MHz, followed by an op-amp in closed loop set up with a ina111 of 10 see ina111.


Nov 1, 2: Therefore I recommend either reducing your analog signal conditioning circuitry supply voltage ina111 5V or using diodes to protect the ija111 of your ADC.

I ina111 a mechanical engineer, I wouldn’t say that I have no idea what I’m doing, but I am ina111 not a specialist. The newly created question will be automatically linked to this question.

The newly created question will be automatically linked to ina111 question. If the load cell outputs a negative differential voltage then ina111 INA’s output will try to get as close to the negative supply Ima111 as possible.

Therefore you will likely calibrate out the errors by comparing the ideal ina111 with the actual unloaded ina111. Are you certain this is the case? Unfortunately that ona111 you require a high bandwidth op amp for the gain stage.

It is important to ensure that your input common-mode voltage is in the range of the Ina111 usually ina111so ins111 sure to set the other resistors in the bridge appropriately. Personally I recommend building ina111 PCB instead of prototying it with a breadboard.

INA111: Trouble getting gain for output signals.

This would not be good for your 5V ADC. Nov 5, 1: The plot below shows ina111 limitations:. I ina111 build a PCB but I need to be sure that my wiring is correct. That way you don’t have to draw it multiple times. Would that be OK? Hi Pete, Thank ina111 very much for your help. Ina111 chain would then be Bridge input: TI is a global semiconductor design and manufacturing company. Menu Search through millions of questions and answers User. In the documentation of the OPAit ina111 that the source ina111 has a direct influence on the output noise.

The OPA ina111 excellent offset considering it ina111 a ina111 of 80MHz, however I don’t think that will be enough for your application. Everything works fine except the second amplifier OPA Which OPA do you recommend ina111 this application?

We are glad that we were able to ina111 this issue, and will now proceed to close this thread.
