4100 V/µs in an 8-SOIC
The LM7171BIM/NOPB is a single-channel voltage feedback op-amp from the VIP™ III series, delivering a 4100 V/µs slew rate in the standard 8-SOIC footprint. That slew rate means the output can swing 20 V peak-to-peak in under 5 ns — fast enough to drive the input stage of a high-speed ADC or a cable driver without the slew-induced distortion that limits lower-speed amplifiers in pulse applications. The -3 dB bandwidth is 220 MHz and the gain-bandwidth product is 200 MHz, so the usable small-signal gain extends well past 100 MHz before the open-loop roll-off dominates. For a gain-of-10 stage the closed-loop bandwidth settles around 20 MHz — enough for video distribution, fast DAC output buffers, or time-domain reflectometry front-ends.
Supply rails and thermal envelope
The supply span runs from 5.5 V minimum to 36 V maximum, covering both single-supply (e.g. 12 V or 24 V industrial rails) and split-supply configurations (±2.75 V to ±18 V). Quiescent draw is 6.5 mA per amplifier — the bias current is low enough that a 12 V rail can power the op-amp without a separate regulator in a multi-amp array. Operating temperature is -40°C to 85°C, which is the industrial-grade range. The 8-SOIC's junction-to-ambient thermal resistance is roughly 120°C/W on a standard 2-layer board; with a 118 mA output current into a 50-ohm load the internal dissipation stays under 700 mW, keeping the die well below the 150°C abs-max junction in still air. Input offset voltage is 200 µV typical and input bias current is 2.7 µA — the bias current is higher than a JFET-input op-amp, so source impedance matters. A 1 kΩ source sees a 2.7 mV DC error from bias alone; for precision DC-coupled stages a lower-impedance path or a trim network is the standard fix.
Package, marking, and lifecycle
The LM7171BIM/NOPB ships in a tube (the standard 8-SOIC rail), surface-mount on a 1.27 mm pitch. The NOPB suffix confirms ROHS3 compliance — no lead, no antimony trioxide, no red phosphorus in the molding compound. The laser etch on the package top should read LM7171BIM; any re-mark or sanded surface is a counterfeit flag that decap X-ray would confirm. Lifecycle status is Active per the manufacturer. The VIP™ III series has no direct pin-compatible second-source from another brand — the BOM position is single-sourced to TI.
