diagramsymbol [~]
Good day.
Trying to recreate a circuit, but I'm not sure what the dot BEFORE the triangle means. I know after it means invertor, does before just mean it's inverted BEFORE, instead of after? Rather confused, and not having luck searching.
Really appreciate the help.
It's the symbol of a current source.
There are different symbols used to represent a current source:
The diagram on page 631 of the user guide has it labeled "Temp. Sensor".
This is the internal Block Diagram for the SD24_A ADC, but it's almost functionally the same for the other ADC Types

Just another way of drawing a logic inverter ("NOT").
The triangle-with-bubble is an inverter: logic high input yields logic low output, and vice versa. Usually the bubble is shown on the output, but in a mixed-logic system, the bubble can be shown on the input instead.
When the bubble is on the input instead of the output, that indicates that the input is an active-low input.
