LMH6622

Dual Wideband, Low Noise, 160MHz, Operational

Amplifiers

General Description

The LMH6622 is a dual high speed voltage feedback opera-

tional amplifier specifically optimized for low noise. A voltage

noise specification of 1.6nV/

cation 1.5pA/ , a bandwidth of 160MHz, and a harmonic

distortion specification that exceeds 90dBc combine to make

the LMH6622 an ideal choice for the receive channel ampli-

fier in ADSL, VDSL, or other xDSL designs. The LMH6622

operates from 2.5V to 6V in dual supply mode and from

+5V to +12V in single supply configuration. The LMH6622 is

stable for A_V≥ 2 or A_V≤ −1. The fabrication of the LMH6622

on National Semiconductor’s advanced VIP10 process en-

ables excellent (160MHz) bandwidth at a current consump-

tion of only 4.3mA/amplifier. Packages for this dual amplifier

are the 8-lead SOIC and the 8-lead MSOP.
