Absent a DAC, I need to drive an ADA4700-1 configured to produce from 0 to -38V. The design requires from 0 to 2.5v for this span. For a set of 8 fixed voltages, is it practical to use the ADG715 to switch a series of voltage dividers to drive my voltage source? (I call it a step attenuator)
Roughly, this:
