LMH6553MRE

Overview

The LMH6553MRE is a high-speed, fully differential amplifier manufactured by National Semiconductor. It features a bandwidth of 900 MHz and includes an integrated output limiting clamp to protect downstream components from overvoltage conditions. The device is designed for applications requiring wide dynamic range and low distortion in signal processing chains.

Feature Summary

• Fully differential architecture for improved noise rejection
• Integrated output limiting clamp for circuit protection
• High bandwidth supporting wideband signal processing

Applications

• Video distribution systems
• Broadband communication interfaces
• Test and measurement equipment

Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, as TI acquired NS. Confirm the suffix 'MRE' corresponds to the specific tape-and-reel packaging variant. Ensure the datasheet version matches the production lot for accurate electrical specifications.

Selection Notes

Select this component when a fully differential configuration with inherent output protection is required. Consider the 900 MHz bandwidth against system frequency needs. Evaluate the need for external clamping if higher voltage tolerance than the internal limit is necessary.

Part Context

This part belongs to the LMH series of high-speed amplifiers. It serves as a bridge between legacy National Semiconductor designs and current Texas Instruments portfolios following the corporate acquisition. The MRE suffix indicates a specific reel-based packaging format.
