Hi，
As described in datasheet of INA3221, when the address pin A0 is connected to power, ground, SCL and SDA, four device addresses can be obtained.
It is understandable to connect pin A0 to the power and ground, but what is the principle of connecting A0 to SCL and SDA to generate a new address, because SCL and SDA are also pulled up to the power. Is this method stable and reliable?
In addition, do we need to connect resistance in series when A0 pin is connected to power supply and ground?
thanks！
