Overview
The LM7171AIM/NOPB is a high-speed voltage-feedback amplifier produced by Texas Instruments. It combines the slewing characteristics of a current-feedback amplifier with the ease of use of a traditional voltage-feedback amplifier. This device is stable for gains as low as +2 or −1, making it versatile for various high-speed signal processing applications. The LM7171AIM/NOPB operates on ±15V and ±5V power supplies, allowing for large signal swings and a greater dynamic range, which is beneficial for applications requiring high signal-to-noise ratios.
