Part Number: INA2331 In the legacy design, INA2331AIPWRG4 is used. Since this part is obsolete now, we are checking for the drop in replacement. We have chosen INA2331AIPWR.B as alternate.
Both are technically same, but what is the difference between…
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…
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 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…
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…
