Part Number: INA238 Other Parts Discussed in Thread: INA226 Tool/software: Hi, among 3 other I2C devices, we have an INA238 on our PCB. The I2C communication with INA238 (0x40@7bit) failed (no ACK), while the other I2C devices on the bus send an acknowledge…
Part Number: INA238 Other Parts Discussed in Thread: INA228 Hi team,
My customer has one question regarding INA238, they want the alert pin only report the overcurrent signal, not including temperature limit, over or under voltage, etc...
Is it possible…
Part Number: INA238 Hello Team, We are using the IC INA238AIDGSTfor one of our applications to measure the voltage. The voltage can be up to 48V. We don't want to measure the current. So can I left the pins IN- and IN+ pins floating?. The I2C signals is…
Hi, By “continually getting same value.”, do you mean the phenomenon is the same as before? Can you step the input shunt voltage through a list of values and list side by side the actual Vshunt and the INA238 measurements? Because current is…

Part Number: INA238 Hello,
I am using the INA238 current sensor in my project, but I am encountering an issue. The current readings I get from the sensor are different from the actual values I set. I'd like to detail this issue and seek help from the…
Part Number: INA238 Hi team,
As for power and current calculation,we can refer to 8.1.2 Current and Power Calculations and 8.2.2 Detailed Design Procedure in datasheet. But customer proposes another method:
(1) Configure ADCRANGE=0 or 1
(2) SHUNT_CAL=default…
Part Number: INA238 Hi team.
Can customer use 25V rating filter cap?
If Vs=3.3V and Vbus is 54V. And 54V power up firslty and then after 1s, 3.3V power up. Is that timing ok?
