  • Forum Post: Re: INA326 EMG amplifier

    TJ10751
    TC and Paul, Sorry for getting back to you so late. I've actually been too busy at work and haven't checked my old gmail account in ages. I'll try to help as much as I can. The EMG amplifier I designed was very sensitive to noise and could not fully eliminate the 50Hz (or 60Hz depending...

  • Forum Post: Any drawback tying all gaurds pins toghether on an INA116 Instrumentation Amp?

    Edward Dempsey
    Hi, We are in the process of utilizing the INA116 in a current PCB design and had a question regarding the connection of the guard pins on the INA116. The engineer that did the board layout ended up tying all guard pins together for simplicity in the board design. I have looked at the INA116 data...

  • Forum Post: INA333, integrated active filter

    richard payne62974
    Is there a way to integrate INA333 with active filter (butterworth) so I can eliminate op-amp that done this? INA333 is used to measure voltage drop as part of current sense. I have +5V and 2.5V comm.

  • Forum Post: Re: Input filterung of INA121

    Bruce Trump
    Many applications do not require filtering. Figure 5 and 7 in the INA121 data sheet merely show how filtering might be implemented if filtering is required. A low-pass filter is generally used to attenuate noise present in the input signal that is higher in frequency than the desired signal. A...

  • Forum Post: Amplifier for chemical oscillator

    Sam Kenny
    Hi, I'm a chemist at the University of Minnesota studying oscillating chemical reactions. I'm using a Pt electrode to electrically monitor the oscillations, and a Vernier voltage probe to record the oscillator voltage over time. The chemical cell produces roughly a sine wave with a period of...

  • Forum Post: Load Cell Amplifier ( Large Temperature Range )

    ismail cetinkaya
    I have designed a load cell amplifier with three opamp in amp. I use this amplifier in baby incubator project. I have sensor module inside incubator and my amplifier circuit is in the module. Module temp can be 45-50C some times because of settled temp of incubator. So , my amplifier out changes +-20mV...

  • Forum Post: Phone current measurement using high-side shunt monitor

    Ekhiotz Vergara
    Hi, I have been measuring the energy consumption of some smartphones using a shunt resistor, but now I would like to add a shunt monitor (unidirectional is enough). Basically, I remove the battery of the smartphone and connect it to a 4V power supply with a shunt resistor between the power supply...
