The LMH6672 is a dual high speed op amp from Texas Instruments that has the ability to drive signals 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 xDSL line driver.
The LMH6672 is a low-cost, dual high-speed operational amplifier designed to drive signals to within 1V of the power supply rails. It features high output drive with low distortion, making it ideal for demanding applications such as single-supply xDSL line drivers. When connected as a differential output driver, it can drive a 50Ω load to a 16.8Vpp swing with -93dBc distortion, fully supporting peak upstream power levels for full-rate ADSL.
