Part Number: INA2331 Other Parts Discussed in Thread: INA331 , TINA-TI , LM27762 , AFE5816 , OPA325 Hi
I'm implementing below circuitry for amplifier section. The input signal voltage will range between 10uV to 10mV. But in the current circuit, the…
Part Number: INA2332 Other Parts Discussed in Thread: INA2331 , I have an amplifier circuit that is configured to use an INA2332 Instrumentation amplifier. Can I use the INA2331 as a drop-in replacement?
As far as I can tell from the datasheet the INA2331…
Hello Nathaly,
Please measure the voltage at pins 2, 3, and 12 of the device (Vin-, Vin+, and REFA). It is of utmost importance to measure at the pins of the device...not anywhere else (e.g. test points). We need to ensure that the device is receiving…
Hello, I made my first tests with INA2331. Two comments, and I believe they are important :
1. Vout limit You told me the output would saturate at 1.6V, but this is not what I see... I have set Vref @ ~0.5V. I see that the output can rise linearly up…
Hi Tamara, thanks for reply. I don´t have the schematic drawn yet, but I can tell exactly the values. Mi VREF is connected to ground, I set a gain of 21.12 V/V (R2=200k ; R1=62k) , with single supply of 5,5V. My common mode voltage range swings between…
Other Parts Discussed in Thread: INA2331 , INA125 , INA2126 Hello,
I'm started a project involving 2 load cells and using this blog as a guide.
It uses the INA125P and a single load cell to read values into a microcontroller.
The INA2331 looks to…
Hi Glenn,
it depends on your actual application. I guess you have carefully read section 8.4.3 of datasheet?
Usually, you have a big electrolytic storage cap at the power supply (left side of upper 10R resistor). This big capacitance with its ESR…
Hi,
I have a similar question about the common-mode input range. With the INA2331, is it possible to have REF=0V with Vs=3.3V and a differential input of 0 to 13.2mV.
I'm confuse with the minimum value of input common-mode range. Would it be preferable…
Hi Michael,
Thank you for reaching out. Input offset voltage in this range will noticeably affect your output, and you are right about considering a part with lower offset as this will definitely improve your accuracy. You are using a dual channel instrumentation…
