LMH6553MR/NOPB

Overview

The LMH6553MR/NOPB is a single-channel fully differential current feedback amplifier from Texas Instruments, designed for high-speed signal processing. It features an output limiting clamp to protect downstream components and operates within a supply voltage range of 4.5 V to 12 V. The device supports a wide operating temperature range from -40°C to +125°C and is housed in an 8-pin HSOIC EP package with tape-and-reel packaging.

Feature Summary

• Fully differential architecture providing balanced signal paths
• Integrated output limiting clamp for circuit protection
• Current feedback topology for high slew rate performance

Applications

• Automotive video signal processing
• High-speed data acquisition systems
• RF intermediate frequency amplification

Procurement Notes

Verify the specific suffix MR against the official datasheet to confirm the HSOIC EP package variant. Ensure the NOPB designation confirms lead-free and RoHS compliance status. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a fully differential output is required alongside robust overvoltage protection. The current feedback architecture suits applications demanding fast transient response. Verify that the 8-pin HSOIC EP package fits the PCB layout constraints and thermal requirements of the target design.

Part Context

This part belongs to the LMH6553 family of high-speed differential amplifiers. It shares functional similarities with other members like the LMH6553SD but differs in package type. The family targets video and RF applications requiring precise differential signaling and high bandwidth capabilities.

Replacement Considerations

The LMH6553SD/NOPB serves as a pin-compatible alternative in an 8-WSON package. Verify thermal dissipation differences between the HSOIC and WSON packages during substitution.
