Part Number: INA238 Hello,
We are currently doing bringup of a board with an INA238 at our power input. We are powering the board at 20V delivering between 0.1 - 7A roughly to the board during operation. We have our INA238 configured with default settings…
Part Number: INA238 Hi expert
Do we need RC filter on VBUS pin? I don't find any recommendation or design in datasheet or EVM. Is it possible to use only one serial R on this pin? Thanks!
Part Number: INA238-Q1 Other Parts Discussed in Thread: INA238 Hi,
I have a set of boards where the INA238's A0 pin is connected to VS and the A1 pin is connected to SDA (address 1001001), but some of them ACK and send data at address 1001001 and others…
Part Number: INA238-Q1 Other Parts Discussed in Thread: INA238 We have a power distribution board with 40 power outputs. Each output can supply 3A, half of them are 28V the other half are 12V.
Example of one of the outputs:
So far we have produced…
Part Number: INA238 Hi Teams,
Regarding the usage of the INA238AIDGSR chip, if we follow the instructions in Table 6-2 and consider the additional 100ns requirement, is it necessary to simulate I2C through software? What is the maximum communication…

Hi,
In addition to 4 temperature sensor devices communicating over the I2C bus, the PCB also includes an INA238 device.
During I2C communication…
Part Number: INA238-Q1 Other Parts Discussed in Thread: INA238 Hi I dont want to do any voltage measurement in my design using INA238, if VBUS pin is unused what should be the termination method for it, shall I leave it floating or connect to GND with…
Part Number: INA238-Q1 Tool/software: Hi Team,
Through current below link driver, we can measure mA current range, but we have a need to measure microampere range. So, what changes need to be done for measuring microampere current through current…
Part Number: INA238 Tool/software: Hi Team
my customer side try to use ADC_CONFIG BIT 2-0 function to check the average value of power.
but they find if they have any setting like 7h,4h,3h.
the power value will return to 0 .
they currently…
Part Number: INA238 Tool/software: Hi,
We use the INA238 for the power monitor for the FANS control, and now, we have below issue for this design:
1. Our paramater is Vbus=54V, and the Vcm=3.3V, the max. output current is 70A, and the min. current…
