1 Refers to differential configuration shown in Figure 64.

2 Please refer to Figure 16 and Figure 17 for the relationship between input current and temperature.

4 The AD8224 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.
