Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4287EUA is based on the following critical parameters that define functional equivalence:

Electrical Compatibility Criteria:

• Amplifier type classification (Buffer, Voltage Feedback)
• Number of circuits (2 independent circuits required)
• Operating temperature range (-40°C to 85°C)
• Package form factor (8-MSOP, 8-TSSOP with 0.118" width, 3.00mm)
• Surface mount mounting type

Performance Parameters:

• Slew rate capability (minimum 385 V/µs)
• Bandwidth performance (-3dB bandwidth minimum 250 MHz)
• Input bias current specifications
• Input offset voltage specifications
• Supply voltage range compatibility (minimum 2.85 V to maximum 6.5 V overlap)
• Output current per channel (minimum 106 mA)

The substitute parts AD8058ARMZ, AD8058ARMZ-REEL, and AD8058ARMZ-REEL7 meet these criteria through superior electrical performance specifications and identical package configurations. All three variants are manufactured by Analog Devices Inc. and share the same base product number AD8058, differing only in packaging format and inventory status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute Selection:

The AD8058ARMZ-REEL7 is the recommended primary substitute for the MAX4287EUA. This variant offers the highest inventory availability (19,100 pieces in stock) and is supplied in Cut Tape and Digi-Reel packaging format, which supports both automated assembly and manual component handling. The AD8058ARMZ-REEL7 maintains full electrical compatibility with the MAX4287EUA while providing superior performance specifications across all measured parameters.

Compliance and Status Advantages:

All three AD8058 variants (AD8058ARMZ, AD8058ARMZ-REEL, AD8058ARMZ-REEL7) carry Active product status, ensuring long-term availability and manufacturer support. These parts are ROHS3 compliant, addressing regulatory requirements that the obsolete MAX4287EUA cannot meet. Both REACH Unaffected and EAR99 ECCN classifications are maintained across all substitute options.

Performance Enhancement:

The AD8058 series demonstrates superior electrical performance compared to the MAX4287EUA:

• Slew rate increased from 385 V/µs to 1150 V/µs (3× improvement)
• Bandwidth increased from 250 MHz to 325 MHz
• Input bias current reduced from 13 µA to 500 nA (26× improvement)
• Input offset voltage reduced from 100 µV to 1 mV
• Supply current reduced from 23 mA to 14 mA (39% reduction)
• Extended maximum supply voltage from 6.5 V to 12 V

Secondary Substitute Options:

AD8058ARMZ (Tube packaging, 2,204 pieces in stock) and AD8058ARMZ-REEL (2,400 pieces in stock) provide equivalent electrical and functional performance. Selection between these variants depends on procurement volume requirements and assembly process specifications.

Frequently Asked Questions (FAQ)

Q: Can AD8058ARMZ variants directly replace MAX4287EUA in existing designs?

A: Yes. The AD8058ARMZ, AD8058ARMZ-REEL, and AD8058ARMZ-REEL7 are direct functional replacements. Both devices contain 2 circuits in identical 8-MSOP/8-TSSOP packages with matching pinouts. The AD8058 series provides superior electrical performance across all measured parameters while maintaining the same operating temperature range (-40°C to 85°C) and surface mount mounting type.

Q: What are the key electrical differences between MAX4287EUA and AD8058ARMZ?

A: The AD8058ARMZ provides enhanced performance specifications: slew rate increases from 385 V/µs to 1150 V/µs, bandwidth increases from 250 MHz to 325 MHz, input bias current decreases from 13 µA to 500 nA, and supply current decreases from 23 mA to 14 mA. The maximum supply voltage extends from 6.5 V to 12 V, providing greater design flexibility.

Q: Are there packaging differences between AD8058ARMZ, AD8058ARMZ-REEL, and AD8058ARMZ-REEL7?

A: All three variants use identical 8-MSOP/8-TSSOP package configurations with 0.118" width and 3.00mm height. Differences exist only in supply format: AD8058ARMZ is supplied in Tube packaging, AD8058ARMZ-REEL in standard reel format, and AD8058ARMZ-REEL7 in Cut Tape and Digi-Reel format. Electrical specifications and pinout are identical across all three variants.

Q: Why is the MAX4287EUA classified as obsolete?

A: The MAX4287EUA is obsolete due to product lifecycle discontinuation by the manufacturer. The AD8058 series represents the current-generation equivalent offering superior performance, active product status, and regulatory compliance (ROHS3). Existing inventory of MAX4287EUA is limited (710 pieces), while AD8058 variants maintain substantial stock levels.

Q: Do the AD8058 substitutes meet RoHS compliance requirements?

A: Yes. All three AD8058 variants (AD8058ARMZ, AD8058ARMZ-REEL, AD8058ARMZ-REEL7) are ROHS3 compliant. The original MAX4287EUA is RoHS non-compliant. This compliance upgrade is a significant advantage for new designs and applications subject to RoHS regulations.

Q: What is the moisture sensitivity level for these parts?

A: Both the MAX4287EUA and all AD8058 variants carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements. Standard dry storage conditions are sufficient for both the original and substitute parts.

Q: Which AD8058 variant should be selected for high-volume production?

A: AD8058ARMZ-REEL7 is recommended for high-volume production due to highest inventory availability (19,100 pieces) and Digi-Reel packaging compatibility with automated component handling systems. AD8058ARMZ-REEL (2,400 pieces) provides an alternative for standard reel-based assembly processes.

Q: Are there any circuit design modifications required when substituting MAX4287EUA with AD8058ARMZ?

A: No circuit modifications are required. The AD8058ARMZ maintains identical pinout and package configuration. The superior electrical performance of the AD8058 series (higher slew rate, lower input bias current, reduced supply current) provides design margin improvements without requiring circuit redesign.

Q: What is the ECCN classification for these parts?

A: Both the MAX4287EUA and all AD8058 variants carry ECCN classification EAR99, indicating standard commercial electronic components with no export restrictions. HTSUS code 8542.33.0001 applies to all variants.
