IMETER-BOOST: Can this boostpack be used to measure uA level power consumption?


Hi ,

I used this EVM a lot and think its function is great.  I used to use this tool to measure the power consumption of Zigbee  and the result  looks like  very close to a real instrument. but recently, I re-read the user guide and datasheet of INA226, it declares that  the LSB of INA226  is 2.5uV, Vos is +-2.5V, 10uV max. and a 0.1Ω shunt resistor is used. According to my understand, it should not support a current measure less than 100uA, otherwise,the offset error is too big.  Please kindly comments if this boostpack is suitable for a 1uA to 10mA current measurement,? thanks.
