LMH6722MA Equivalent & Substitute Parts

Part Overview

The LMH6722MA is a quad-channel current feedback video amplifier manufactured by Texas Instruments, housed in a 14-SOIC surface mount package. This integrated circuit is designed for high-speed video amplification applications requiring wideband performance and fast slew rates. The LMH6722MA is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain identical electrical specifications and package compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LMH6722MA are qualified based on strict equivalence of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Number of Circuits: 4 channels
• -3dB Bandwidth: 400 MHz
• Slew Rate: 1800 V/µs
• Current - Supply: 5.6 mA
• Current - Output / Channel: 70 mA
• Voltage - Supply Range: 8V ~ 12.5V, ±4V ~ 6.25V
• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Series: VIP10™

The identified substitute parts maintain identical electrical performance specifications and physical package dimensions, enabling direct functional replacement in existing circuit designs. Both substitute parts are classified as active products, ensuring continued availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The LMH6722MA is classified as obsolete. Direct substitution is available through two active equivalent parts: LMH6722MA/NOPB and LMH6722MAX/NOPB, both manufactured by National Semiconductor. Both substitute parts maintain identical electrical specifications and package configurations, ensuring functional compatibility in existing designs.

Compliance Considerations:

The original LMH6722MA carries ROHS3 compliance certification. Both substitute parts are manufactured under the same VIP10™ series designation and maintain equivalent supply voltage ranges and thermal performance characteristics. Selection between the two substitute options should be based on inventory availability and procurement lead times, as electrical performance is identical.

Packaging and Handling:

All three parts utilize the 14-SOIC surface mount package with identical physical dimensions (0.154" width, 3.90mm). The LMH6722MA specifies Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. Substitute parts are suitable for direct PCB assembly replacement without modification to existing footprints or assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can LMH6722MA/NOPB and LMH6722MAX/NOPB be used interchangeably with the original LMH6722MA?

A: Yes. Both substitute parts maintain identical electrical specifications across all critical parameters: 400 MHz bandwidth, 1800 V/µs slew rate, 5.6 mA supply current, 70 mA output current per channel, and identical supply voltage ranges. Package dimensions and mounting type are identical, enabling direct PCB replacement.

Q: What is the difference between LMH6722MA/NOPB and LMH6722MAX/NOPB?

A: Both parts are functionally equivalent with identical electrical specifications and package configurations. The difference lies in product status classification and inventory availability. Both are active products manufactured by National Semiconductor within the VIP10™ series.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: The original LMH6722MA is certified ROHS3 compliant. Compliance certifications for the substitute parts are not specified in the provided data. Both substitute parts are manufactured under the same series designation and maintain equivalent electrical and thermal characteristics.

Q: What package considerations apply to these parts?

A: All three parts use the 14-SOIC surface mount package with identical physical dimensions (0.154" width, 3.90mm). No PCB footprint modifications are required when substituting between these parts. The Moisture Sensitivity Level 1 rating indicates no special moisture handling requirements.

Q: Can the LMH6722MA be used in new designs, or should substitutes be specified?

A: The LMH6722MA is classified as obsolete. For new designs and ongoing production, specify either LMH6722MA/NOPB or LMH6722MAX/NOPB to ensure continued component availability and manufacturing support.
