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.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
