The INA223EVM is a platform for evaluating the performance of the INA223 a voltage output device that monitors the current, bus voltage, and power of a supply line by sensing a voltage drop across a shunt at common mode voltages from 0V to 26V. The common mode voltage range is independent of the supply voltage. The low offset of the Zero drift architecture enables current sensing with maximum drops across the shunt as low as 10mV, 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 configurations. The programmable gain feature also allows the device to be operated over a much wider dynamic current load range without having to switch the sensing element used.
