Parameter Comparison

Engineering Selection Recommendations

The MAX4080FASA+ is a direct functional and mechanical equivalent to the MAX4080FASA. Both parts share identical electrical specifications, package geometry, and compliance certifications.

Key Distinction: The MAX4080FASA+ maintains Active product status, whereas the MAX4080FASA is classified as Obsolete. This status difference reflects manufacturing lifecycle positioning rather than technical capability. The MAX4080FASA+ is supplied in Tube packaging, while the original part packaging specification is not provided.

For new designs or production continuity, the MAX4080FASA+ is the appropriate selection due to its Active status and confirmed availability. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX4080FASA+ be used as a direct replacement for MAX4080FASA in existing designs?

A: Yes. The MAX4080FASA+ is electrically and mechanically equivalent. All electrical parameters, operating ranges, and package specifications are identical. The primary difference is product lifecycle status: MAX4080FASA+ is Active while MAX4080FASA is Obsolete.

Q: What is the significance of the "+" suffix in MAX4080FASA+?

A: The "+" suffix indicates a variant designation within the MAX4080 product family. In this case, it denotes the Active production version with Tube packaging. The electrical and functional specifications remain unchanged from the base MAX4080FASA designation.

Q: Are there any packaging considerations when switching from MAX4080FASA to MAX4080FASA+?

A: The mechanical package specification is identical: 8-SOIC (0.154", 3.90mm Width). Both parts are Surface Mount components with the same pin configuration and footprint. The difference is in supply packaging: MAX4080FASA+ is supplied in Tube format. This does not affect PCB assembly or circuit operation.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both MAX4080FASA and MAX4080FASA+ are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both parts, indicating no moisture sensitivity restrictions.

Q: What is the operating temperature range for these parts?

A: Both parts operate across -40°C to 125°C. This range is suitable for industrial and automotive applications requiring extended temperature performance.

Q: What supply voltage range do these current sense amplifiers support?

A: Both parts support a supply voltage span of 4.5 V (minimum) to 76 V (maximum), enabling operation in high-voltage sensing applications including automotive and industrial systems.
