Overview
The LMH6321TSX/NOPB is a single open-loop high-speed buffer amplifier manufactured by Texas Instruments. It operates within an extended industrial temperature range of -40°C to +125°C and utilizes a 7-pin TO-263 (DDPAK) surface-mount package. The device provides a 300 mA output current capability with adjustable current limit functionality. It features a bandwidth of 110 MHz, enabling high-frequency signal processing applications.
Feature Summary
- Provides high-speed buffering for demanding signal paths
- Delivers substantial 300 mA output drive capability
- Includes adjustable current limit protection mechanism
Applications
- High-speed signal buffering in communication systems
- Driving low-impedance loads in test equipment
- Video signal distribution circuits
Procurement Notes
Verify the specific suffix 'TSX' indicates the tape-and-reel packaging format compatible with automated assembly processes. Confirm the 'NOPB' designation ensures lead-free construction compliant with RoHS standards. Cross-reference the manufacturer's latest datasheet to validate pinout configurations and thermal characteristics for the TO-263 package before finalizing procurement specifications.
Selection Notes
Select this component when high output current and wide bandwidth are required in a compact surface-mount form factor. The adjustable current limit feature offers flexibility for protecting downstream components. Ensure the design accommodates the thermal requirements of the TO-263 package under maximum load conditions.
Part Context
This part belongs to the LMH6321 family of high-speed buffers from Texas Instruments. It shares core performance characteristics with other variants like the LMH6321MR but differs in package type and shipping configuration. The family is designed for applications requiring fast transient response and high drive strength.
Replacement Considerations
Direct substitutes include other LMH6321 variants such as LMH6321MR/NOPB, provided the package change from TO-263 to PSOP-8 is acceptable. Verify pin compatibility and thermal management requirements when considering alternative packages.
