What the 990 µA supply current means for battery-powered designs
The 990 µA quiescent supply current is the number that matters for a battery-powered signal chain. At this draw the op-amp can stay alive in a sensor node without draining the cell overnight — paired with the 1.7 V minimum supply, it runs directly off a single lithium cell through most of its discharge curve. The rail-to-rail output keeps the full ADC code range without an extra reference rail, which saves another regulator slot on the board.
The 150 µV input offset is tight enough that you can skip a trim pot in most single-supply 12-bit applications. Input bias current of 10 pA keeps errors negligible when the source impedance is in the tens of kΩ range.
