3.4 Hold Time

Hold time is the time that the device waits before releasing the attenuation if it has been applied. The maximum is 500 ms and it goes down to 0 ms for an immediate release.

Hold time can be used to avoid gain oscillations due to temperature fluctuations and it can be fine-tuned depending on the end application.
