At 750 µA quiescent supply current, this op-amp sits in the low-power zone — not micropower, but low enough that a battery-powered sensor front-end won't drain overnight. The 0.2 pA input bias current is essentially negligible for most signal conditioning, so you won't see offset drift from source impedance.
The SOT-23-5 footprint is a standard 5-pin small-outline transistor package — easy to hand-solder or reflow, and common enough that the PCB land pattern is in every EDA library. The 50 mA output per channel is enough to drive an ADC input or a modest headphone load, but don't plan on driving a relay coil directly.
No end-of-life notice, no last-time-buy deadline to manage.
