THD Readings vs. Common-Mode Voltage
Total harmonic distortion of the AD8610/AD8620 is well below
0.0006% with any load down to 600 Ω. The AD8610 outperforms
the OPA627 for distortion, especially at frequencies above 20 kHz.
Noise vs. Common-Mode Voltage
The AD8610/AD8620 noise density varies only 10% over the
input range, as shown in Table 5.

Settling Time
The AD8610/AD8620 have a very fast settling time, even to a
very tight error band, as can be seen from Figure 60. The AD8610/
AD8620 are configured in an inverting gain of +1 with 2 kΩ input
and feedback resistors. The output is monitored with a 10×,
10 MΩ, 11.2 pF scope probe.
