LMH6672 Datasheet | National Semiconductor

Description The LMH6672 is a low cost, dual high speed op amp capable of driving signals to within 1V of the power supply rails. It features the high output drive with low distortion required for the demanding application of a single supply x DSL line driver. When connected as a differential output driver, the LMH6672 can drive a 50Ω load to 16.8VPP swing with only - 93d Bc distortion, fully supporting the peak upstream power levels for upstream full-rate ADSL. The LMH6672 is fully specified for operation with 5V and 12V supplies. Ideal for PCI modem cards and x DSL modems.
