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/
, a current noise specifi-
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 AV 2 or AV −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.
