Engineering Selection Recommendations

The LMH6672MA/NOPB serves as a direct functional equivalent to the obsolete LMH6672MA. Both components share identical electrical specifications across all measured parameters and maintain the same 8-SOIC package footprint.

Status Consideration: The LMH6672MA/NOPB carries an Active product status, ensuring continued manufacturer support, availability of technical documentation, and compliance with current manufacturing standards. The original LMH6672MA is classified as Obsolete, indicating discontinued production and limited long-term availability.

Compliance & Certifications: Both parts are designated as EAR99 under export control regulations and fall under HTSUS code 8542.33.0001. The LMH6672MA/NOPB maintains compatibility with current supply chain requirements for active components.

Packaging Specification: The /NOPB suffix indicates lead-free, RoHS-compliant packaging. This designation reflects modern manufacturing standards and environmental compliance requirements.

For new designs or production continuity, the LMH6672MA/NOPB is the appropriate selection due to its active status and equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the LMH6672MA/NOPB replace the LMH6672MA in existing designs?

A: Yes. Both components are electrically identical across all specified parameters: 135 V/µs slew rate, 90 MHz bandwidth, 525 mA output current per channel, and identical supply voltage requirements (5 V to 12 V). The 8-SOIC package dimensions are identical, requiring no PCB layout modifications.

Q: What is the significance of the /NOPB suffix?

A: The /NOPB designation indicates lead-free, RoHS-compliant packaging. This reflects compliance with current environmental and manufacturing standards. Functionally, the device operates identically to the base part number.

Q: Why is the LMH6672MA classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The LMH6672MA/NOPB, with Active status, represents the current production equivalent and is the recommended selection for ongoing applications.

Q: Are there any thermal or reliability differences between these parts?

A: No differences are specified in the provided parameters. Both components operate across the identical temperature range (-40°C to 150°C) and share all electrical specifications.

Q: What is the maximum output current capability?

A: Each channel delivers 525 mA maximum output current. With two channels, total output current capability is 1050 mA under specified operating conditions.

Q: Can these amplifiers operate from a single supply voltage?

A: The specified supply voltage range is 5 V to 12 V. Specific single-supply or dual-supply configuration requirements are not provided in the parameter set and must be verified against application-specific circuit design requirements.
