Selection note — what the 3 MHz GBW and 160 µA quiescent mean for your BOM
It delivers a rail-to-rail output stage while drawing only 160 µA of quiescent supply current. For a low-power sensor front-end or a 5 V single-supply signal chain, the 160 µA supply is the spec that decides the power budget — it keeps the thermal rise negligible in a cramped enclosure and extends battery life in portable gear. The 3 MHz GBW supports audio-band filtering and moderate-speed data acquisition without burning the extra milliamps a wider-bandwidth part would cost.
Supply range and temperature — where it fits
The OPA704UA operates from a 4 V to 12 V supply span, covering single 5 V and dual ±5 V rails.
Output drive and package reality
The Bulk shipping medium means the parts arrive in tubes or trays, not on tape; factor that into your pick-and-place feeder setup if you're running high-volume reels.
