National LMH6622 Data Manual

Summary

This advanced dual operational amplifier (LMH6622) is engineered for superior performance in receiving channels due to its remarkably low noise and 160MHz ultra-wide bandwidth. The included manual provides comprehensive technical data, including full electrical specifications, dynamic performance curves (bandwidth, slew rate), and operating guidelines. This amplifier is the ideal choice for high-precision applications such as xDSL receivers (ADSL/VDSL), advanced instrumentation front ends, ultrasound preamplifiers, and cellular base stations requiring exceptional signal integrity.
