LM7171 Datasheet | National Semiconductor

Description The LM7171 is a high speed voltage feedback amplifier that has the slewing characteristic of a current feedback amplifier; yet it can be used in all traditional voltage feedback amplifier configurations. The LM7171 is stable for gains as low as +2 or - 1. It provides a very high slew rate at 4100V/µs and a wide unity-gain bandwidth of 200 MHz while consuming only 6.5 m A of supply current. It is ideal for video and high speed signal processing applications such as HDSL and pulse amplifiers. With 100 m A output current, the LM7171 can be 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 signal-to-noise ratio. The LM7171 offers low SFDR and THD, ideal for ADC/DAC systems. In addition, the LM7171 is specified for ± 5V operation for portable applications. The LM7171 is built on National’s advanced VIP™ III (Vertically integrated PNP) plementary bipolar process. n n n n n n n n n Easy-To-Use Voltage Feedback Topology Very High Slew Rate: 4100V/µs Wide Unity-Gain Bandwidth: 200 MHz - 3 d B Frequency @ AV = +2: 220 MHz Low Supply Current: 6.5 m A High Open Loop Gain: 85 d B High Output Current: 100 m A Differential Gain and Phase: 0.01%, 0.02˚ Specified for ± 15V and ± 5V Operation Applications n n n n n n n n HDSL and ADSL Drivers Multimedia Broadcast Systems Professional Video Cameras Video Amplifiers Copiers/Scanners/Fax HDTV Amplifiers Pulse Amplifiers and Peak Detectors CATV/Fiber Optics Signal Processing Features (Typical Unless Otherwise Noted) Typical Performance Large Signal Pulse Response AV = +2, VS = ± 15V Connection Diagrams 8-Pin DIP/SO DS012385-2 Top View 16-Pin Wide Body SO DS012385-1 DS012385-3 Top View VIP™ is a trademark of National Semiconductor Corporation. © 1999 National Semiconductor Corporation DS012385 .national.
