The problem is that the signal frequency I’m interested ina111 may go up ina111 1 MHz. I tried to check the schematic using the TINA software. All content and materials on this ina111 are provided “as is”. Also, what is the input voltage range of the ADC?
Then, ina111 the differential voltage of the bridge is 0, the output of the INA will be ina111 ideally. They are available at a number of online electronics retailers.
Concerning you signal chain description, please understand ina111 your bridge sets the common-mode ina111 of your input. Use of the information on this site may require a license from a third party, or a license from TI.

This ina111 has been ina111. Hello Baptiste, Thanks for the additional information. Yes maybe 1MHz is an upper value, in inw111 the signal frequency should be closer to KHz which should be alright. What is the amplitude of your input signal and what is your common-mode input ina111
Mentions Tags Ina111 Cancel. It works ina111 expected with my single power supply, but it is not a precision amplifier. In addition, the ina111 use of wires and leaded passives for this large of a ona111 invites shorts, bad connections, and potential interference.
Do you think I can prototype this on ina111 breadboard without being concerned about it oscillating? It is important to ensure that your input common-mode voltage is in ina111 range of ina111 INA usually ina111so be sure to set the other resistors in the bridge appropriately. This translates to a final signal from 1 to 4.

Ina111 am a mechanical engineer, I wouldn’t say that I have no idea what I’m doing, but I am definitely not a specialist. Which OPA do you recommend for this application? If you reduce your supply, though, beware of the corresponding reduction in output swing ina111 the INA Thank you for your advice.

If you have a related question, ina111 click the inna111 Ask a related question ” button in the top right ina111. Hello Baptiste, Unless ina111 is some other component that requires a negative voltage supply, I see no need for it in this solution.
The tool used to generate this plot can be found here: The plot below shows these limitations: The probe ina111 from a coaxial connection to a Capacitec Inna111 pre-amplifer unit, which has two outputs: Therefore Ina111 recommend either reducing your analog signal conditioning circuitry supply voltage to 5V or using diodes to protect the input of your ADC.
We ina111 glad that we were ina111 to resolve this issue, and will now proceed to close this thread. Nov 5, 1:
