LM7171

LM7171 SNOS760D – MAY 1999 – REVISED FEBRUARY 2024 LM7171 Very High Speed, High Output Current, Voltage Feedback Amplifier 1 Features Typical values unless otherwise noted Easy-to-use voltage-feedback topology Very high slew rate: 4100V/μs Wide unity-gain bandwidth: 200MHz −3dB frequency at AV = +2: 220MHz Low supply current: 6.5mA High open-loop gain: 85dB High output current: 100mA Differential gain and phase: 0.01%, 0.02º Specified for ±15V and ±5V operation 2 Applications HDSL and ADSL drivers Multimedia broadcast systems Professional video cameras Video amplifiers Copiers, scanners, fax HDTV amplifiers Pulse amplifiers and peak detectors CATV and fiber optics signal processing 3 Description The LM7171 is a high-speed voltage-feedback amplifier that has the slewing characteristic of a current-feedback amplifier, but can be used in all traditional voltage-feedback amplifier configurations. The LM7171 is stable for gains as low as +2 or −1. The device provides a very high slew rate at 4100V/μs and a wide unity-gain bandwidth of 200MHz, while consuming only 6.5mA of supply current. The LM7171 is an excellent choice for video and high-speed signal processing applications, such as HDSL and pulse amplifiers. With 100mA of output current, the LM7171 is used for video distribution, as a transformer driver, or as a laser diode driver. Operation on ±15V power supplies allows for large signal swings and provides greater dynamic range and signa...
