1 When the output sinks more than 4 mA, use a 47 pF capacitor in parallel with the load to prevent ringing. Otherwise, use a larger load, such as 10 kΩ.
2 Refers to the differential configuration shown in Figure 63.
3 Refer to Figure 14 and Figure 15 for the relationship between input current and temperature.
4 Differential and common-mode input impedance can be calculated from the pin impedance: ZDIFF = 2(ZPIN); ZCM = ZPIN/2.
5 The AD8224 can operate up to a diode drop below the negative supply; however, the bias current increases sharply. The input voltage range reflects the maximum
allowable voltage where the input bias current is within the specification.
6 At this supply voltage, ensure that the input common-mode voltage is within the input voltage range specification.
7 The AD8224 is characterized from 40°C to +125°C. See the Typical Performance Characteristics section for expected operation in this temperature range.
