Part Number: INA2191 Tool/software: Hi Mr. / Miss.
I have modified the measurement circuit for our application.
I only added U27(AQY212G3HS) which is a photorelay. If U27 is added, the current measurement fails (only 1 or -1 uA). If U27 is removed…
Part Number: INA2191 Dear seniors
I am currently encountering a very strange problem using INA2191 A3. Please also take the time to help provide comments or guidance.
I use an INA2191 A3 to measure the current of my circuit. From 0uA ~200uA. Use ADC…
Part Number: INA2191 Hi Team,
We have planned to use this part INA2191A2IYBJR in our design.
As per the layout guidelines the filled via size is not mentioned in the datasheet.
Could you please share filled via details.
Thanks & Regards,

Hello,
I have a strange behavior with the attached circuit. As soon as i attach a 24V to S+, the power supply gets in 'current surge protection'. May you please let me know why this would happen ?
Edited: It happens with/without…
Part Number: INA2191 Hello,
I designed a circuit to read the current of a pressure sensor (4-20mA standard) and I connected the sensor as depicted in the attached picture but all the time the ADC value is zero.

Hi, I am planning to use this device with a shunt resistor for measuring a 20V and -20V power supply current. is the circuit below correct?
what I don't know is or if this is ok for the measurement of the current the negative…
Part Number: INA2191 Other Parts Discussed in Thread: INA253 , INA240 Can "INA2191A1" be used for a solenoid and valve control application? Do we then need to add any additional protection to the component?
If it can't be used, can you suggest a component…
Part Number: INA2191 Dear TI -Expert,
I have two questions:
Is there a reference buffer inside the INA2191? Which output impedance of the reference voltage source is acceptable?
I am confused about "the INAx191 uses a capacitively coupled amplifier…
