# Op-amp gain and headroom
# Scope: Ideal non-inverting op-amp closed-loop gain.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

feedback = 10000 ohm
ground = 1000 ohm
input = 0.2 V

gain := 1+feedback/ground
output := input*gain [V]

check output rail budget: output <= 5 V

scenario alternative: feedback = 8000 ohm
