... Factory-trimmed on-chip resistors provide 0.1% gain accuracy while decreasing design size, cost, and layout. Three versions are available in this amplifier family: single/dual/quad open-loop, unity-gain-stable devices (MAX4281/MAX4282/MAX4284); single/dual fixed-gain devices (MAX4174/MAX4274); and single/ dual devices with fixed gain plus internal V at the noninverting input (MAX4175/MAX4275). All amplifiers feature rail-to-rail outputs and drive a 1k Ω ...
