Tool/software:
I am using this IC to monitor the current. along with differential input, I need it's residual current of this IC. In datasheet I cheked for any input resistance to ground but I did not found it. Could you please provide the resual current or input resitance data?
Input resistance here is resistance from +ve and -Ve input to ground.
This is example from other IC for input resistance. In TI INA193, this resistance is not specified. I need these resistance values
There is no fixed resistance. As shown in figures 9 and 10, the input bias current is constant for input voltages beyond the supply.
Hello Prachi,
Thank you for your post. Clemens is pointing you in the right direction in terms of what specs will help with quantifying the input behavior.
We do not provide input resistance to GND, however, we provide input bias current which will give you an important set of data in these plots to help you properly size your shunt resistor to ensure that you are at least 100x the maximum input bias current over your input common mode range.
Depending on your supply voltage, please reference figure 9 or figure 10.
I hope this helps,
Joe
