Overview
The LMH6552SDX/NOPB is a fully differential current-feedback amplifier manufactured by Texas Instruments. It features a -3dB bandwidth of 1.5 GHz and a slew rate of 3800 V/µs. The device operates on a single supply voltage ranging from 4.5 V to 12 V, or dual supplies of ±2.25 V to ±6 V. It draws a typical supply current of 22.5 mA per channel and provides an output current capability of 80 mA. The component is housed in an 8-WSON package with exposed pad.
Feature Summary
- Provides high-speed signal processing with a 1.5 GHz bandwidth for wideband applications.
- Features a high slew rate of 3800 V/µs to minimize distortion in fast-changing signals.
- Offers flexible power supply options supporting both single and dual voltage configurations.
Applications
- Video distribution systems requiring high bandwidth
- Wireless infrastructure base stations
- Test and measurement equipment
Procurement Notes
Verify the specific suffix 'SDX' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging quantity and variant status. Ensure the ordering part number matches the required package type and environmental compliance specifications listed in the latest product documentation before finalizing procurement.
Selection Notes
Select this component when a fully differential output is required alongside high-speed performance characteristics. The current-feedback architecture is suitable for driving capacitive loads in video and RF applications. Compare the 1.5 GHz bandwidth and 80 mA output drive against system requirements to ensure adequate signal integrity and noise margins are maintained.
Part Context
This device belongs to the LMH6552 family of fully differential amplifiers designed for high-frequency signal conditioning. It serves as a core active component in analog front-end circuits where balanced signal paths are necessary to reject common-mode noise. The series supports various packaging options including SOIC and WSON formats for different board space constraints.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Potential alternatives within the same family include the LMH6552MAX/NOPB for SOIC-8 packaging compatibility. Verify pinout and electrical parameter equivalence before substituting.
