Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4287EUA+ is determined by the following critical parameters:

Package Compatibility: The substitute parts must utilize the 8-TSSOP or 8-MSOP package format with 0.118" width and 3.00mm pitch to ensure mechanical and electrical compatibility with existing PCB layouts.

Functional Classification: Substitute parts must operate as voltage feedback amplifiers within the linear amplifier category, maintaining the ADC driver functionality required for signal conditioning applications.

Electrical Performance: Substitute parts must support the operating temperature range of -40°C to 85°C and maintain compliance with RoHS3 and REACH regulations.

Regulatory Compliance: All substitute parts must carry identical RoHS3 compliance status and REACH unaffected designation to meet procurement and environmental standards.

The following active parts meet these substitution criteria:

• AD8058ARMZ
• AD8058ARMZ-REEL
• AD8058ARMZ-REEL7

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes: The AD8058ARMZ series (AD8058ARMZ, AD8058ARMZ-REEL, AD8058ARMZ-REEL7) are active products from Analog Devices Inc. that provide direct functional replacement for the obsolete MAX4287EUA+. All three variants share identical electrical specifications and package geometry.

Product Status Advantage: Unlike the MAX4287EUA+, all AD8058ARMZ variants maintain active product status, ensuring long-term availability and continued manufacturer support.

Compliance Alignment: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original part.

Packaging Variants: Selection between AD8058ARMZ, AD8058ARMZ-REEL, and AD8058ARMZ-REEL7 depends on procurement packaging requirements. AD8058ARMZ is supplied in tube packaging, AD8058ARMZ-REEL in standard reel format, and AD8058ARMZ-REEL7 in cut tape and Digi-Reel® format. All three are electrically and mechanically identical.

Inventory Availability: AD8058ARMZ-REEL7 offers the highest current inventory level (19,100 pieces), followed by AD8058ARMZ-REEL (2,400 pieces) and AD8058ARMZ (2,204 pieces).

Frequently Asked Questions (FAQ)

Q: Can the AD8058ARMZ series directly replace the MAX4287EUA+ without PCB modifications?

A: Yes. The AD8058ARMZ series shares identical package geometry (8-TSSOP, 8-MSOP with 0.118" width and 3.00mm pitch) and surface mount mounting type, enabling direct substitution on existing PCB layouts without design changes.

Q: What is the difference between AD8058ARMZ, AD8058ARMZ-REEL, and AD8058ARMZ-REEL7?

A: These three part numbers represent the same integrated circuit with identical electrical specifications and package format. The differences are in packaging and delivery format: AD8058ARMZ uses tube packaging, AD8058ARMZ-REEL uses standard reel packaging, and AD8058ARMZ-REEL7 uses cut tape and Digi-Reel® packaging. Selection depends on procurement and assembly requirements.

Q: Are the substitute parts compliant with the same regulatory standards as the MAX4287EUA+?

A: Yes. All AD8058ARMZ variants maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original MAX4287EUA+.

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

A: The AD8058ARMZ series operates across -40°C to 85°C, covering standard industrial and medical device temperature requirements.

Q: How do the electrical specifications of the AD8058ARMZ compare to the MAX4287EUA+?

A: The AD8058ARMZ series provides documented electrical specifications including 1150V/µs slew rate, 100 MHz gain bandwidth product, 325 MHz -3dB bandwidth, 500 nA input bias current, and 1 mV input offset voltage. The MAX4287EUA+ specifications for these parameters are not provided in available documentation.

Q: Is the AD8058ARMZ suitable for medical ultrasound imaging and sonar applications?

A: The AD8058ARMZ is a voltage feedback amplifier with performance characteristics suitable for ADC driver applications. Application suitability depends on specific circuit requirements and signal conditioning needs of the target system.

Q: What is the moisture sensitivity level of the substitute parts?

A: All AD8058ARMZ variants carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage and handling.
