SETTLING TIME
Settling time is the amount of time it takes the amplifier output
to reach and remain within a percentage of its final value. This
is an important parameter in data acquisition systems. Because
most bipolar DAC converters have current output, an external
op amp is required to convert the current to voltage. Therefore,
the amplifier settling time plays a role in the total settling time
of the output signal. A good approximation for the total settling
time is
The ADA4000-1/ADA4000-2/ADA4000-4 settle to within 0.1%
of their final value in less than 1.2 μs. The settling time has been
tested by using the configuration circuit in Figure 34.
