Current noise is defined and measured with balanced source voltage exceeds ±1.8V, the input current should be limited to 25mA. resistors. The resultant voltage noise (after subtracting the resistor noise on an RMS basis) is divided by the sum of the two source resistors to obtain current noise. 1115fa 3
