It delivers a 1 MHz gain bandwidth product with a 1 V/µs slew rate, drawing just 150 µA per channel. Input bias current sits at 0.2 pA, so it won't load high-impedance sources like photodiodes or pH probes.
The 150 µA per channel supply current keeps quiescent power low. Rail-to-rail output on a 2.7 V rail provides swing near the supply. The 0.2 pA input bias allows high-impedance feedback without offset errors.
