Original question:
Part Number: INA169
HI,
I'm using INA169 for current sensing. How to calculate the current sense range ?? How to calculate that for different R(Load) & R(shunt) Values.?? Please reply the equation also.(Ex- If i select 1K as R(L) & 10 ohms as shunt what is the range and how to calculate it... external power supply-5V)
Thanks.
Hello Isuru,
The output high will either be limited by the VCM of the input or the Vsupply. What is the VCM you are using? Also with a large resistance such as 10Ω you also need to worry about the input voltage limitation.
Here are the equations you need to worry about from the datasheet. See equation 1 and equation 2 for the maximum output and see that the max input is 0.5V.
