Hello,
I'm using UCD74106 and I've got some important variations from one board to another on current measurement.
5% tolerance on the internal current measurement + 5% error gain + 1% external resistor + 10mA of INL at UCD9246 ADC, I was expected some decent accuracy.
With current of 0.5A, I sometimes read 0.25A, sometimes 0.75A (on different boards but exact same hardware)
I suspect the "Zero amp load offset", in the datasheet, only a typical value is provided, could you give me an estimated min/max ?
Thank you,
Thomas
