Other Parts Discussed in Thread: INA240
Hi,
My customer is considering INA213.
(Customers plan to connect Vref to GND.)
I got three questions from customers.
Could you give me your advice?
1. Can this device adjust the GAIN by connecting 22 KΩ in series with IN + pin and IN - pin respectively?
Customers want to adjust the gain to 23.8.
1MΩ/(20KΩ+22KΩ)=23.8
2. INA213 can not install an low pass filter in the background with built-in resistor.
For that reason, Noise is amplified by gain.
Please tell me how to counter it.
3. As related to question 2,
Is there a possibility of oscillation due to power supply noise or input signal noise?
Best Regards,
