    Hi Naeem, No problem. Best of luck with your project. Best Regards, Chris Featherstone

  • RE: INA331: Supply Voltage.

    Hi, Zach The diagram above shows the circuit and noise waveform when using a single power supply for INA331. When changing to dual power supplies for INA331, the noise waveform changes as shown below. In all of the above tests, the input is in an inactive…

  • INA331: Input impedance reference

    Resolved
    Part Number: INA331 Hi Amps Team, I have a fairly simple question about the input impedance spec of the INA331( and TI's amplifiers in general): I wanted clarity that the impedance spec on the input was in reference to ground and not the differential…

  • INA331: Why the output of INA331 should be less than VDD-1.2V

    Resolved
    Part Number: INA331 Hi all when i see the datasheet of INA331, I find that the output voltage of INA331 can not be more than VDD-1.2v（page9 &page10） So does it means that if my VDD=3.3v， my maximum output signal voltage can not be more than 2.1V…
