Why these work well
  • 0603 footprint matches the rest of your passives.
  • 0 Ω, 0.1 W rating is more than enough for a logic-level jumper between GAIN and GND.
  • All three series are stocked at Digikey/Mouser/Arrow, so sourcing should be straightforward.
Pick any one; they’re functionally identical for this purpose. After adding it, label it R_GAIN and wire:
GAIN pin → R_GAIN → GND net.
Let me know if you’d like me to place and connect the resistor for you.
