AO and Optional AO LED
The AO output is the ANDED combination of either the overvoltage comparator
outputs or the under-voltage comparator outputs and is controlled by the state of
the AOSEL. AO pin is active “LOW”. Footprint for an optional AO LED, D1, and
current limiting resistor, R26, have been included on the board to allow a user to
visually indicate an out of window event. See BOM for recommended
components.
