LM6121/LM6221/LM6321

High Speed Buffer

General Description

These high speed unity gain buffers slew at 800 V/µs and

have a small signal bandwidth of 50 MHz while driving a 50Ω

load. They can drive 300 mA peak and do not oscillate

while driving large capacitive loads. The LM6121 family are

monolithic ICs which offer performance similar to the

LH0002 with the additional features of current limit and

thermal shutdown.

Features

n High slew rate: 800 V/µs

n Wide bandwidth: 50 MHz

n Slew rate and bandwidth 100% tested

n Peak output current:

n High input impedance: 5 MΩ

n LH0002H pin compatible

n No oscillations with capacitive loads

n 5V to 15V operation guaranteed

n Current and thermal limiting

300 mA

™

These buffers are built with National’s VIP (Vertically Inte-

grated PNP) process which provides fast PNP transistors

that are true complements to the already fast NPN devices.

This advanced junction-isolated process delivers high speed

performance without the need for complex and expensive

dielectric isolation.

n Fully specified to drive 50Ω lines

Applications

n Line Driving

n Radar

n Sonar
