Other Parts Discussed in Thread: DAC8811
In a circuit such as Figure 9. of the TLC7528 datasheet, excluding effects of the circuit external to the DAC, for DAC selection, how can figure out the frequency limitations of a circuit like mentioned above? Presumably, the settling time of the DAC is proportional to the frequency limit of using the DAC as an attenuator or even as a digitally controlled resistor of sorts, but how can I figure this out? I am interested in incorporating the tlc7528 or another multiplying DAC into a function generator I am designing as a digitally controlled attenuator and other similar circuits, but I am unsure of how directly the settling time applies to the frequency limits on it.
Thank you!
