The supply span ranges from 3 V to 36 V, making it equally at home in 3.3 V battery-powered circuits and ±15 V industrial rails.
The 100 µV input offset and 80 nA input bias are typical for a general-purpose bipolar stage — not precision territory, but fine for most feedback and control loops. The 10 mA output per channel can drive a modest load directly; for heavier loads you'll buffer it.
There is no direct pin-compatible replacement listed in the official documentation. For a functional alternative with similar bandwidth and rail-to-rail output, the ADA4691-2ACPZ-R7 offers a 3.6 MHz gain bandwidth in a dual-channel package, but it uses a different package (LFCSP) and has a much lower input bias current (0.5 pA). Verify footprint compatibility before substituting.
