Part Number: INA381-Q1 Other Parts Discussed in Thread: INA381 Dear TI experts,
My customer consider INA381-Q1 for their new project.
And they should measure the current under 100mA using INA381-Q1.
Is it possible to use INA381A2(with 2mohm shunt…
Hi Shunsuke,
Shunsuke Yamamoto said: Does common-mode input voltage apply CMPIN pin and CMPREF pin as well as IN+ pin and IN- pin?
No. It only applies to IN+ and IN-.

Yamamoto-san,
Thanks for the question and using the E2E forum.
Shunsuke Yamamoto said: My customer would like to add the capacitor between IN+ pin and IN- pin to suppress the high frequency noise. Is it possible to do it? The user guide of EVM shows…
Part Number: INA381-Q1 Hello TI support team,
In the following thread the digital input leakage current of the INA381-Q1 was discussed: INA381-Q1: Leakage current of Digital inputs over full operating temperature range - Amplifiers for…
We've used…
Part Number: INA381-Q1 Tool/software: Please confirm whether the parameter "digital leakage input current", with typical 1µA, corresponds to the leakage current in the CMPREF pin. If so, could you please confirm whether most of this current is due to…
Part Number: INA381-Q1 Tool/software: Dear TI experts,
My customer drew their schematic using INA381-Q1. Could you review this schematic?
They just want to VOUT high if HEATER_CONTROL is high. And B+ is 12V of car battery.
Please let me know if…
Part Number: INA381-Q1 Tool/software: Hello TI Support Team,
We are currently evaluating the INA381-Q1 and noticed that the datasheet specifies a nominal leakage current of 1µA at 25°C for the digital inputs. However, we would appreciate it if you could…
Part Number: INA381-Q1 Tool/software: Hello TI,
I am looking for some information regarding the internal comparator of INA381-Q1. It's good that the "High-level input voltage", "Low-level input voltage" and "Alert low-level output voltage" are specified…
Part Number: INA381-Q1 Other Parts Discussed in Thread: INA381 Tool/software: Hi Team,
Customer wants to know the total power consumption of INA381. There is no information in the datasheet. So please check it and let me know.
Regards,
Part Number: INA381-Q1 Hello TI,
I would like to use INA381-Q1 and I have a question regarding transition time for the RESET signal. Since the RESET pin is digital input, I would like to know minimum and maximum rise and fall times for the same. I have…
