1 Differential and common-mode impedance can be calculated from the pin impedance: ZDIFF = 2(ZPIN); ZCM = ZPIN/2.

2 The AD8220 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.

3 The AD8220 is characterized from −40°C to +125°C. See the Typical Performance Characteristics section for expected operation in that temperature range.
