Technical details

That slew rate means it can swing a 5 V output step in under 4 ns, which is what you need when driving a high-speed ADC input or a video line driver. The 5.3 mA supply current is the trade-off: you get the speed without the 10+ mA draw of a full current-feedback part, but the voltage-feedback topology means you still need to watch the feedback resistor value for stability at high closed-loop gains.

The supply span runs from 4.5 V to 33 V, so it works on a single 5 V or 12 V rail, or split supplies like ±5 V. No AEC-Q100 grade here, so it is not qualified for under-hood automotive, but the industrial temperature band is enough for most chassis-mounted or indoor gear.

Surface-mount only — no through-hole variant available.

ROHS3 compliant, no exemptions to chase. For a new design, this part is a low-risk choice from a lifecycle standpoint — no last-time-buy clock ticking.
