Otherwise, use a larger load, such as 10 kΩ. 2 Differential and common-mode input impedance (ZDIFF and ZCM) can be calculated from the pin impedance (ZPIN): ZDIFF = 2(ZPIN); ZCM = ZPIN/2. 3 The AD8220-EP can operate up to a diode drop below the negative supply but the bias current increases sharply. The input voltage range reflects the maximum allowable voltage where the input bias current is within the specification. 4 At the minimum supply voltage of ±2.25 V, ensure that the input common-mode voltage is within the input voltage range specification.
