LM7171 Very High Speed, High Output Current, Voltage Feedback Amplifier May 1999 LM7171 Very High Speed, High Output Current, Voltage Feedback Amplifier General 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 mA of supply current. It is ideal for video and high speed signal processing applications such as HDSL and pulse amplifiers. With 100 mA 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) complementary 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 dB Frequency @ AV = +2: 220 MHz Low Supply Current: 6.5 mA High Open Loop Gain: 85 dB High Output Current: 100 mA 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 www.national.com Ordering Information Package Temperature Range Industrial −40˚C to +85˚C 8-Pin DIP 8-Pin CDIP 10-Pin Ceramic SOIC 8-Pin Small Outline 16-Pin Small Outline LM7171AIN, LM7171BIN LM7171AMJ-QML LM7171AMJ-QMLV LM7171AMWG-QML LM7171AMWG-QMLV LM7171AIM, LM7171BIM LM7171AIMX, LM7171BIMX LM7171AIWM, LM7171BIWM LM7171AWMX, LM7171BWMX 5962-95536 5962-95536 Military −55˚C to +125˚C Rails Rails Trays Rails Tape and Reel Rails Tape and Reel M16B N08E J08A WG10A M08A Transport Media NSC Drawing www.national.com 2 Absolute Maximum Ratings (Note 1) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.
