The common-mode voltage range is independent of the supply voltage. The low offset of the Zerø-Drift architecture enables current sensing with maximum drops across the shunt as low as 10 mV, full-scale. The INA223 includes a two-wire interface used for adjusting the configuration settings of the device. The interface is used to control the signal (current shunt voltage, bus voltage, or power) that is directed to the device output. Multiple gain and attenuation settings can be programmed through the two-wire interface to allow for application-specific co.
