What this op-amp brings to the bench
The Analog Devices LT6015HS5#TRMPBF is a single-supply, general-purpose op-amp that squeezes a 3 V to 50 V supply range into a TSOT-23-5 package. The input offset is trimmed to 55 µV, which is tight enough for current-sense and bridge-amplifier circuits, and it draws only 325 µA of supply current, so it won't drain a battery in always-on sense loops.
The TSOT-23-5 package is small — about 2.9 mm by 1.6 mm — so it fits on tight boards, but that also means rework needs a hot-air station or a fine-tip iron. No lab bench required, but you will want a steady hand and a magnifier if you are swapping it in the field.
