What this dual voltage-feedback amp brings to the board
The rail-to-rail output stage lets it swing close to the supply rails — handy in single-supply designs where headroom is tight. Each channel draws 6.9 mA supply current, so the total budget for the pair sits around 14 mA before load.
Package and mounting
A 485 V/µs slew rate means this amp can track fast edges — think video sync pulses or high-speed data lines — without slewing into distortion. The 210 MHz -3 dB bandwidth supports clean gain up to tens of MHz, depending on the closed-loop gain you set. For a gain-of-2 buffer driving a 50-ohm back-terminated cable, it holds good phase margin. Input bias current is 7.5 µA and input offset voltage is 1 mV, both typical for a bipolar-input voltage-feedback design at this speed.
Package and supply — fitting it into the layout
The SOT-23-8 package is compact — about 2.9 mm by 1.6 mm — so it fits tight channel-count boards. Supply range is 9 V to 11 V, which is a narrow window compared to general-purpose op-amps; you need a regulated 9 V or 10 V rail, not a loosely-tolerated 12 V bus.
