INA226AIDGSR Typical Application Circuit
The INA260 has a maximum CMRR of 150uA/V. Convert this to voltage terms by multiplying 150uA/V by 2 mOhms, which equals 300nV/V --> 20*log(1V/300nV) = 130dB minimum. The INA226 has a minimum CMRR of 126dB. The offset (10uV), offset drift (100nV/degC), and ADC shunt voltage LSB (2.5uV) of the two devices are the same. From above, we can know that the two components are the same.
