Part Number: INA190EVM Other Parts Discussed in Thread: INA190 , Tool/software: Hello all, I want to design a shutdown circuit as seen in the precision labs series CSA videos.
I'm doing a gate sweep of an FET where I'm applying 0-50V on the gate and…

Hi Experts,
Using the INA190EVM board, may I know what gain variant and value of shunt resistor to use when reading a uA to ~30mA current?
Also, what other filter components…

Dear TI colleague
I am using INA190EVM as an amplifier for a PIN photo-detector. The light input is CW light, no modulation is on. The current is below 0.1mA. Rsense…
Part Number: INA190-Q1 Other Parts Discussed in Thread: INA190 , , INA190EVM Tool/software: Hello,
is there a difference in the die for the different packages for the INA190 series?
More specififcally, does the INA190A3QDCK have the same die as the…
Hi Chae Hui Cheon, You could monitor the ripple either by recreating this circuit using our EVM: https://www.ti.com/tool/INA190EVM or by simulating it on TINA-TI using this model: sbomai7b.tsc

Part Number: INA190 Other Parts Discussed in Thread: TVS2700 , , In order to provide context, I will use the INA190 as a 4-20mA receiver, and I have concerns about how to protect its inputs. The idea is to use it in Loop Current mode. The power supply…
Thank you for your reply, Carolus.
I have ordered the INA190EVM.
Can I just use normal 1% resistors in the Rsense position for these boards? I appreciate your careful explanations.
I will finish watching the videos while I wait for the boards to…
Hey Ted,
I think the rules you have enumerated are very reasonable for this use of INA3221. I suggest also heeding the instruction of the Layout Guidelines in datasheet Section 11.
I would say a couple other additional potential rules are:
- If…
Part Number: INA210 Other Parts Discussed in Thread: INA190EVM , , INA190 Hello,
I just began to use theINA210 using the configuration of the INA190EVM. I have a questions to confirm that everything is set correctly.
1.I create a new combination…
Hello Kotaro,
Inside the INA190 there is a bidirectional diode in between IN+ and IN- with a ~3.3 kOhm of current-limiting resistance. So for V_differential of 3V there could be 909uA of differential current into IN+ and then out of IN-. I just measured…
