OptionalconfigurationThe averaging and conversion times; the mode is chosen per conversion.
OptionalcurrentA current step to use instead, in microamps per count.
OptionalmaxThe largest current the shunt will carry, in microamps, which sets the finest current step the calibration allows.
OptionalshuntThe shunt resistance in milliohms.
How an INA226 driver measures. A field left out keeps the default: a 100 milliohm shunt sized for 3.2 A and the power-on register settings.
