LMH6552SD/NOPB

Overview

The LMH6552SD/NOPB is a single-channel differential current feedback amplifier manufactured by Texas Instruments, succeeding the National Semiconductor lineage. It features a 1.5 GHz -3dB bandwidth and a 3800 V/µs slew rate. The device operates on a supply voltage of 4.5V to 12V (±2.25V to ±6V) with a typical supply current of 22.5mA. It delivers an output current of 80mA per channel and utilizes an 8-WSON package.

Feature Summary

• Provides fully differential signal processing for high-speed applications
• Utilizes current feedback architecture to achieve wide bandwidth
• Supports low-voltage operation within a 4.5V to 12V range

Applications

• High-speed video buffering and driving
• RF intermediate frequency amplification
• Data acquisition systems requiring differential signaling

Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired the National Semiconductor product line. Confirm the specific suffix 'SD' indicates the 8-WSON package variant rather than the MAX SOIC version. Ensure the NOPB suffix confirms lead-free and RoHS compliance status prior to ordering.

Selection Notes

Select this component when a single-channel differential output is required alongside high slew rates. Compare against the LMH6553 for higher output current needs or the LMH6551 if lower power consumption is prioritized over maximum bandwidth. Ensure the 8-WSON thermal pad is properly connected to the PCB ground plane for optimal performance.

Part Context

This part belongs to the LMH655x family of high-speed differential amplifiers designed for demanding analog signal paths. It serves as a successor to legacy National Semiconductor designs, offering improved integration in a compact footprint while maintaining the electrical characteristics necessary for broadband signal integrity.

Replacement Considerations

LMH6552MAX/NOPB offers identical electrical specifications but utilizes an 8-SOIC package instead of the WSON form factor.
