The LM7171 is a National Semiconductor very high speed, high output current voltage feedback amplifier with the slewing characteristic of a current feedback amplifier, yet it can be used in all traditional voltage feedback amplifier configurations. It is ideal for video and high speed signal processing applications such as HDSL and pulse amplifiers.
The LM7171 is a high‑speed voltage‑feedback amplifier that combines the fast slewing of a current‑feedback device with the flexibility of a voltage‑feedback topology. It operates from +5 V to +36 V supplies, delivers up to 100 mA output current, and offers a very high slew rate of 4100 V/µs and a 200 MHz unity‑gain bandwidth, making it suitable for video, high‑speed signal processing, and laser‑diode driver applications.
The datasheet provides detailed absolute‑maximum ratings, DC and AC electrical characteristics for both +15 V and +5 V operation, typical performance curves, and package information (8‑Pin DIP, 8‑Pin SOIC, MDIP). It also includes ordering information, connection diagrams, and notes on life‑support policy and RoHS compliance.
