Unfortunately digikey nor mouser have no INA233EVM in stock ;-(.
Same for arrow.
Part Number: INA233EVM Other Parts Discussed in Thread: INA233 Hi,
Firstly, I have an issue with calculating the value for current using the value from the 8C register. I am using i2c/PMBus (little endian format) commands to read and write to the registers…
Hello Stefano,
Do you mean reading two INA233s with a USB-to-GPIO EVM? This should be a viable solution. You could also use the USB-SM-DIG adaptor as well. This comes with the INA233EVM and works with the INA233EVM GUI software.
Hope this helps.
Best…
Hello SHH,
I am looking into your issue. Unfortunately our IT has blocked installation of the INA233EVM software for the moment, while I wait to fix that issue. Perhaps I can get a few more details from you and your customer to determine whether the part…
Part Number: INA260EVM Other Parts Discussed in Thread: INA233EVM , INA226EVM , I'm looking to choose between the INA260EVM, INA226EVM, and INA233EVM. The integrated shunt resistor of the 260 is nice, but not absolutely required. I'm wondering if I…
Hello Karen,
Thanks for using the forum to answer your question.
Question I have is when you are comparing the measurements do you make the current and the bus voltage measurements as well? Is it the current or bus voltage that does not match your…
Hello Ron,
So I ran a test in the lab with our INA233EVM. For this test I powered the INA233 with an external 3.3 V supply. After applying the supply I wrote to the MFR_ADC_CONFIG and MFR_CALIBRATION registers, and subsequently read from the READ_VIN…
Hi Guang,
I have continued to experiment with different settings.
And it appears that reducing the speed to 100kHz has avoided the problem!
However, the problem persists at 200kHz and 400kHz, despite great signal integrity and all other communication working…
SMART,
While I'm checking out your other questions in the lab today, I'll see about this as well and let you know what I find. For reference, I'll be using the INA233EVM to validate the addresses.
Part Number: INA226
Hello,
(I was looking at the INA226EVM and INA233EVM dev kits, I was wondering which you would suggest?
Requirements:
It would be nice to have accurate measurements in the 10uA to 1mA range and the decent measurements at the 1mA…
