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 AV ≥ 2 or AV ≤ −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.
