Hi Atharv,
In addition to lowering the gain as Kai suggested, can you please clarify the voltages you are feeding into the INA? At any instant during the measurement, what do you see on IN+ and IN- of the INA? I would like to make sure that the input…
Part Number: INA111 Other Parts Discussed in Thread: INA331 , INA818 , INA121 , INA332 , , LMP7721 , TINA-TI Hello all,
I am in the process of developing a circuit to measure the device current, the minimum device current in the order of picoamp. The shunt…
Hi,
in section REFERENCE datasheet says: "The reference terminal defines the zero output voltage level."
So, from this statement it is already clear that an AC input signal will not work with Vref=0 in your circuit:
Not only that you are unable…
Other Parts Discussed in Thread: LM837 , INA332 I am trying to simulate a 6 stage op amp design. The last 4 stages will use a LM837 part. There in no macro model for this part. However I saw on the forums where a TI Engineer said a MAX410 part was close…
Thank you very much for your reply.
I checked my desgin again. The schematic and PCB was correct. But when I set the voltage between IN+ and IN- from 0 to 20mV, the OUT(pin4) was always about 0V.
I checked my BOM again. I found a problem. The device mark…
Part Number: INA2332 Other Parts Discussed in Thread: INA332 Hello,
I'm seeing a strange thing when trying to use one circuit of an INA2332 to measure the differential voltage generated by a thermocouple. If I replace the thermocouple with a short…
Part Number: XTR115 Other Parts Discussed in Thread: REF200 , INA326 , INA332 , TINA-TI , XTR116 , INA322 Hi,
I am trying to design 4 to 20 mA transmitter using XTR115.In my application resistance vary from 330E to470E,using this variable I was generate PWM…
Part Number: XTR115 Other Parts Discussed in Thread: INA332 Hi,
I have XTR115 but I don't have instrumentation amplifier.I want to check 4-20mA current at the output of XTR115.So it is possible to check by applying 40-200uA at IN pin with series resistance…
Hi Zak,
Thank you for the quick reply and valuable suggestions, I have noted the bridge configuration. will update the schematic accordingly.
For the instrumentation amplifier I can go for INA332 as low cost option, please suggest any concern.
Will…
