3 Description
The LMH6622 is a dual high speed voltage feedback
operational amplifier specifically optimized for low
noise. A voltage noise specification of 1.6nV/√Hz, a
current noise specification 1.5pA/√Hz, a bandwidth of
160 MHz, and a harmonic distortion specification that
exceeds 90 dBc combine to make the LMH6622 an
ideal choice for the receive channel amplifier in
ADSL, VDSL, or other xDSL designs. The LMH6622
operates from ±2.5 V to ±6 V in dual supply mode
and from +5 V to +12 V in single supply configuration.
The LMH6622 is stable for A_V ≥ 2 or A_V ≤ −1. The
fabrication of the LMH6622 on TI's advanced VIP10
process enables excellent (160 MHz) bandwidth at a
current consumption of only 4.3 mA/amplifier.
Packages for this dual amplifier are the 8-lead SOIC
and the 8-lead VSSOP.
