Other members of the AD962X amplifier family are the AD9621 (G = +1), AD9623 (G = +4), and the AD9624 (G = +6). A separate data sheet is available from Analog Devices for each model. Each generic device has been designed for a different minimum stable gain setting, allowing users flexibility in optimizing system performance. Dynamic performance specifications such as slew rate, settling time, and distortion vary
from model to model. The table below summarizes key perfor-
