Overview
The LMH6552SD/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. The output stage provides a drive capability of 80 mA per channel with a differential output configuration. The component is housed in an 8-pin WSON package.
Feature Summary
- Provides high-speed signal processing with a 1.5 GHz bandwidth for wideband applications
- Features a fast slew rate of 3800 V/µs to minimize transient distortion
- Offers robust output drive capability suitable for demanding load conditions
Applications
- Video buffering and line driving
- High-speed data acquisition systems
- RF intermediate frequency (IF) amplification
Procurement Notes
Verify the specific suffix 'SD' confirms the 8-WSON package variant when sourcing. Ensure the ordering part number includes '/NOPB' to guarantee lead-free compliance and RoHS3 status. Confirm the manufacturer is Texas Instruments to avoid counterfeit components. Cross-reference the DigiKey or Mouser part numbers for accurate availability checks.
Selection Notes
Select this component when a fully differential architecture is required for noise rejection. The current feedback topology supports high slew rates independent of gain settings. Consider the 80 mA output drive if interfacing with low-impedance loads. Verify that the 1.5 GHz bandwidth meets the system's signal integrity requirements without excessive filtering.
Part Context
This device belongs to the LMH6552 series of fully differential amplifiers designed for video and broadband applications. It complements other TI solutions like the LMH6553, which offers lower bandwidth but includes output limiting clamp features. The series utilizes PowerWise technology to balance performance with power consumption.
Replacement Considerations
LMH6552MAX/NOPB: Same electrical specifications but in an SOIC-8 package.
