LMH6622

LMH6622 Dual Wideband, Low Noise, 160MHz, Operational Amplifiers February 2002 LMH6622 Dual Wideband, Low Noise, 160MHz, Operational Amplifiers General Description The LMH6622 is a dual high speed voltage feedback operational amplifier specifically optimized for low noise. A voltage noise specification of 1.6nV/ , a current noise specification 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 amplifier 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 enables excellent (160MHz) bandwidth at a current consumption of only 4.3mA/amplifier. Packages for this dual amplifier are the 8-lead SOIC and the 8-lead MSOP.
