Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMH6715MA is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Package compatibility: 8-SOIC form factor (0.154", 3.90mm Width)
• Circuit count: Dual-channel (2 circuits) configuration
• Amplifier topology: Current feedback architecture
• Supply voltage range: Compatibility with 10V ~ 12V single supply or ±5V ~ 6V dual supply operation
• Output current capability: Minimum 70 mA per channel
• Slew rate: Minimum 1300 V/µs for signal fidelity preservation

Identified Substitute Categories:

1. Direct Pin-Compatible Substitute: LMH6715MA/NOPB (National Semiconductor) — identical electrical specifications and package configuration
2. Functional Equivalent with Enhanced Performance: MAX4225ESA+ (Analog Devices Inc./Maxim Integrated) — meets or exceeds all critical parameters with improved bandwidth and compliance status

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-for-Pin Compatibility):

The LMH6715MA/NOPB from National Semiconductor provides identical electrical performance and package configuration to the original LMH6715MA. This part maintains active product status, ensuring continued availability and manufacturer support. Selection of LMH6715MA/NOPB is appropriate for applications where existing circuit designs require no modification and where the 400 MHz bandwidth specification is sufficient.

For New Designs and Enhanced Performance Applications:

The MAX4225ESA+ from Analog Devices Inc./Maxim Integrated is designated as an active product with ROHS3 compliance, providing superior long-term supply chain stability and regulatory alignment. This device exceeds the LMH6715MA specifications in bandwidth (1 GHz versus 400 MHz) and output current capability (80 mA versus 70 mA per channel). The MAX4225ESA+ operates within compatible supply voltage ranges and maintains the required 8-SOIC package format. Selection of MAX4225ESA+ is appropriate for new system designs, applications requiring enhanced bandwidth performance, and environments with RoHS compliance requirements.

Compliance Considerations:

The MAX4225ESA+ carries ROHS3 compliance certification, whereas the LMH6715MA is RoHS non-compliant. Organizations subject to RoHS regulatory requirements should prioritize MAX4225ESA+ for new procurement and design activities.

Frequently Asked Questions (FAQ)

Q: Can the LMH6715MA/NOPB be used as a direct replacement for the LMH6715MA?

A: Yes. The LMH6715MA/NOPB is electrically and mechanically identical to the LMH6715MA, with identical pin configuration, electrical specifications, and 8-SOIC package dimensions. The primary distinction is product status: LMH6715MA/NOPB is actively supported by National Semiconductor, whereas the original LMH6715MA is designated "Not For New Designs" by Texas Instruments.

Q: What are the key differences between the LMH6715MA and MAX4225ESA+?

A: The MAX4225ESA+ provides enhanced bandwidth (1 GHz versus 400 MHz) and increased output current capability (80 mA versus 70 mA per channel). Both devices share identical package format (8-SOIC), dual-channel configuration, and current feedback amplifier topology. The MAX4225ESA+ operates within compatible supply voltage ranges and offers superior compliance status (ROHS3 compliant versus RoHS non-compliant).

Q: Are the LMH6715MA and MAX4225ESA+ pin-compatible?

A: Both devices utilize the 8-SOIC package format with identical physical dimensions (0.154", 3.90mm Width). Pin compatibility must be verified against specific application schematics, as current feedback amplifier topologies may require application-specific biasing networks. Consult device datasheets for detailed pinout and application circuit requirements.

Q: What supply voltage ranges are supported by substitute parts?

A: The LMH6715MA/NOPB supports 10V ~ 12V single supply or ±5V ~ 6V dual supply operation, identical to the original LMH6715MA. The MAX4225ESA+ supports a supply voltage span of 5.7V minimum to 11V maximum, providing broader compatibility with single and dual supply configurations.

Q: Which substitute part should be selected for RoHS-compliant applications?

A: The MAX4225ESA+ carries ROHS3 compliance certification and is the appropriate selection for applications subject to RoHS regulatory requirements. The LMH6715MA and LMH6715MA/NOPB are RoHS non-compliant.

Q: What is the moisture sensitivity level (MSL) for substitute parts?

A: Both the LMH6715MA and MAX4225ESA+ are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Are substitute parts available in the same packaging format?

A: Yes. All identified substitute parts (LMH6715MA/NOPB and MAX4225ESA+) are supplied in 8-SOIC surface mount packages with identical physical dimensions (0.154", 3.90mm Width), enabling direct PCB compatibility without layout modifications.
