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.
Refers to the differential configuration shown in
Refer to
Differential and common-mode impedance can be calculated from the pin impedance: Z
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.
The AD8224 is characterized from −40°C to +125°C. See the
