For motor driver or comparator applications, consult the specific part number’s datasheet (e.g., – which is a video/TV IC, requiring a different pinout). The op-amp configuration described here covers >80% of hobbyist uses.
Example: If R1=1kΩ, R2=10kΩ, Gain = 11x. This diagram shows both op-amps used: first stage (gain), second stage (buffer/level shifter).
