MJ,
Great question!
I will work to get the necessary product lines involved where I can to get you recommendations for space constrained environments. For current sensing, I would recommend having a look at the INA216, and the INA191. These devices come…
Part Number: TPS61391 Other Parts Discussed in Thread: TPS61390 , INA191 Hello,
My customer has the following questions about TPS61391 spec on page #5 of the datasheet.
They would like to use TPS61390 at IAPD = up to 4mA. In this case, how much would…
Other Parts Discussed in Thread: INA190 , INA191 , INA186 , INA333 After working on this for a few days I need some ideas. I have a 3.3V load that can vary from 10uA to 150mA when plugged in. I can't afford more than .1V drop in the sensing circuit and need…
Part Number: INA169 Other Parts Discussed in Thread: INA190 , INA191 Hi team,
Good day.
What is the minimum (step) differential voltage that INA169 can detect? What is the minimum sense voltage we can provide to INA169 without any error and how to calculate…
Just to back up what I'm saying with a quick calculation:
The minimum sense voltage in your first application is 7mV. The %error due to offset voltage is dominant at minimum input and is computed as simply (Vos/Vsense)*100.
Using typical offset:
…
Part Number: INA226EVM Other Parts Discussed in Thread: INA226 , INA219 , INA253 , INA190 , INA191 , INA233 Good day! There is a task - to measure voltage (0-36V) and current (~ 200-300uA). Is INA219 or INA226 suitable for this? Or what can be advised in my…
Hello user,
We have models available for these devices that may help links below. Adding resistors will not decrease the input bias current but could protect the input from voltage changes.

Part Number: INA233 Other Parts Discussed in Thread: LMP92064 , INA190 , INA191 , INA186 Dear Sirs,
My customer would like to use INA233 to develop the product, may I know the sensed current range is or not support to "uA (1.00 E-06)" level?
Part Number: INA301-Q1 Other Parts Discussed in Thread: INA301 , INA300-Q1 , INA200 , INA200-Q1 , INA193 , INA191 , INA186-Q1 , INA190-Q1 , , INA300 How do I estimate the input bias current for a lower supply for example 3.3V? And how do I estimate the max bias…
