LM6125 Datasheet | National Semiconductor

Description The LM6125 family of high speed unity gain buffers slew at 800 V/µs and have a small signal bandwidth of 50 MHz while driving a 50Ω load. These buffers drive ± 300 m A peak and do not oscillate while driving large capacitive loads. The LM6125 contains unique features not found in power buffers; these include current limit, thermal shutdown, electronic shutdown, and an error flag that warns of fault conditions. These buffers are built with National’s VIP™ (Vertically Integrated PNP) process which provides fast PNP transistors that are true plements to the already fast NPN devices. This advanced junction-isolated process delivers high speed performance without the need for plex and expensive dielectric isolation. n n n n n n High output current: ± 300 m A Stable with large capacitive loads Current and thermal limiting Electronic shutdown 5V to ± 15V operation guaranteed Fully specified to drive 50Ω lines Applications n Line Driving n Radar n Sonar Features n High slew rate: 800 V/µs Simplified Schematic and Block Diagram DS009222-1 DS009222-2 Numbers in () are for 14- pin N DIP.
