The rail-to-rail output stage lets it swing close to the supply rails in single-supply designs — handy for battery-powered sensor conditioning, portable instrumentation, or general-purpose signal buffering where every microamp counts.
Supply range and output swing — what matters for the BOM
The 2.1 V minimum supply means this part works straight off a 3.3 V rail with headroom to spare, and the 5.5 V max covers 5 V logic supplies. The rail-to-rail output is the feature that saves you an external level shifter when the ADC input range matches the supply. Input offset is 800 µV max, input bias current 10 pA — good enough for precision DC paths in portable gear.
Active lifecycle — no end-of-life surprises
No last-time-buy risk on the horizon for this line — it stays in production for new designs and replacement orders alike.
