The 130 kHz gain bandwidth product sets the usable closed-loop bandwidth: at a gain of 100, expect a 1.3 kHz small-signal bandwidth — adequate for slow sensor outputs like thermocouples, RTDs, or strain gauges. The 0.02 pA input bias current is essentially zero for most source impedances — a 1 MΩ source contributes only 20 nV of additional offset error, so you can skip the buffer stage.
It is ROHS3 compliant.
The gain bandwidth product is 130 kHz. This sets the usable bandwidth at a given closed-loop gain — for example, at a gain of 100 the small-signal bandwidth is about 1.3 kHz.
Yes, the output type is rail-to-rail, allowing the output to swing close to both supply rails in single-supply applications.
