Part Number: INA190 Hello,
I cannot find IN+ input leakage under the conditions from my title.
Is this something TI can provide? It is important in my application.
My question refers to IN191.
Thanks!
Part Number: INA199 Other Parts Discussed in Thread: INA190 , INA191 , INA186 Hi team,
ASUS now want to use the INA199A3DCKR material and connect the Supply Voltage, IN+, and IN– pins to DC_IN 24V. Calculated based on a tolerance of ±5%, the voltage will…

I need a way to measure low current on a negative voltage -24V.
I there a way to connect a current sensing amplifier for this negative common mode.
The parts I found are limited to…
Hi,
Just FYI – INA181 is the equivalent of INA180, and capable of bi-directional. However it will have similar behavior as INA199 as far as your application is required.
There are some high input impedance current sense amplifiers such as INA186…

We are trying to develop a receiver that allows reading 4 – 20mA current from industrial transmitters and converting it to…
Hi Vasu,
Thank you for your interest in INA317. Unfortunately this device does have an input common-mode limitation 100mV above the negative supply. If a negative supply is available, the INA317 can be used for low-side current shunt but this is not possible…
Peter,
Thank you for the detailed answer. It was what I needed. A dual channel version would not be optimal for my application. I'll check out the INA191.
Again, Thank you,
David
Hi Pedro,
As you mentioned, 3-decade is a big range to cover with accuracy. It might be possible with a simple solution as proposed. The concern however is if the accuracy requirement can be satisfied at 1mA.
INA4290 is a great choice, but I encourage…
Hello MJ,
Thanks for the question and using the E2E forum.
So if sensing at true 0V is needed your going to need to look at bidirectional devices without this your going to end up saturating to ground on the low end at some point. INA190 and INA2191 are…

Dear Community,
We're working on 2 highly cost-sensitive application use cases where we have to measure the voltage drop across a Resistor connected…
