Hello, I have a question about a section in the Hardware Reference Manual (UG-587, p. 390) entitled "Precision Voltage Reference vs. RCAL". That entire section contains only two sentences ... and two rather mysterious sentences at that.
Those two sentences claim that the choice of RCAL somehow affects the performance of the precision references. However, the figure on the previous page, which shows the schematic for the precision references, shows RCAL is not involved there.
How can the performance of the references (transient response, load regulation etc.) by affected by RCAL? Is some documentation missing? I've attached notes to clarify my question.
