Current-feedback amplifier for high-speed signal chains
Supply current sits at 1 mA, which is notably low for this speed grade — a useful trait when the rail budget is tight. Input offset voltage is 1 mV typical, and input bias current is 2 µA; these are reasonable numbers for a current-feedback design, though not the strong suit of the part — the speed and drive are the headline.
The 600 V/µs slew rate is the parameter that sets this part apart from a general-purpose op-amp. For a 2 V peak-to-peak output swing, the amplifier can transition in roughly 3.3 ns, so it handles 10 MHz square waves cleanly without slew-rate limiting. Compare that to a typical 10 V/µs general-purpose op-amp, which would round the same edge into a triangle. The current-feedback topology means the bandwidth stays relatively flat as you increase gain — unlike a voltage-feedback amplifier where gain and bandwidth trade off directly. The 370 MHz -3 dB bandwidth is specified for the part, and in practice you get most of that bandwidth across gains of 1 to 5. For higher gains, the bandwidth does roll off, but the slew rate remains the limiting factor only for large-signal conditions.
Active status, standard package, industrial temperature range
The NOPB suffix indicates ROHS3 compliance — no lead intentionally added, and no exemptions for the main alloy elements. The package is the standard 8-pin SOIC (0.154-inch body width, 3.90 mm), a widely used footprint that matches many existing board layouts. The part ships in Tube form, which is typical for low-volume prototyping and small production runs; if you need Tape & Reel for automated assembly, check the alternate ordering options from TI.
The supply span runs from 4.5 V minimum to 12 V maximum. That 4.5 V floor means a single 5 V rail works, but a 3.3 V-only system does not — you need at least 4.5 V total across the supply pins. For a 75 Ω video load, you get a clean 2 V swing with margin. The current-feedback architecture also means the output impedance is low, so driving capacitive loads is less problematic than with some voltage-feedback designs, but TI's datasheet still recommends a small series resistor (10-50 Ω) for loads above 20 pF to maintain phase margin.
