MAX4387EUA Equivalent & Substitute Parts

Part Overview

The MAX4387EUA is a buffer and voltage feedback amplifier integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This device contains 2 circuits in an 8-uMAX/uSOP surface mount package and is classified as obsolete. The MAX4387EUA features a slew rate of 385 V/µs and -3dB bandwidth of 130 MHz, with a supply voltage range of 2.85 V to 6.5 V and operating temperature range of -40°C to 85°C.

Due to its obsolete product status, locating new original inventory of the MAX4387EUA presents supply chain challenges. Active substitute parts are available from Analog Devices Inc. that maintain functional compatibility through equivalent electrical and mechanical parameters, enabling direct replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4387EUA is determined by compatibility across the following critical parameters:

Package and Mounting Compatibility: All substitute parts maintain the 8-MSOP surface mount package with 0.118" width (3.00mm), ensuring mechanical and PCB layout compatibility.

Circuit Configuration: All substitute parts contain 2 circuits, matching the dual-channel architecture of the MAX4387EUA.

Operating Temperature Range: All substitute parts support the -40°C to 85°C operating temperature range, maintaining thermal performance specifications.

Supply Voltage Range: Substitute parts operate within supply voltage ranges that encompass or exceed the MAX4387EUA specification (2.85 V to 6.5 V minimum and maximum).

Amplifier Type: All substitute parts are classified as voltage feedback amplifiers, functionally equivalent to the buffer and voltage feedback amplifier type of the MAX4387EUA.

The AD8058ARMZ, AD8058ARMZ-REEL, and AD8058ARMZ-REEL7 are direct substitutes that meet these criteria. These parts are manufactured by Analog Devices Inc. and maintain active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MAX4387EUA is classified as obsolete, while all three substitute parts (AD8058ARMZ, AD8058ARMZ-REEL, AD8058ARMZ-REEL7) maintain active product status. Active status ensures continued manufacturing support, availability, and technical documentation updates.

Regulatory Compliance: The MAX4387EUA is RoHS non-compliant. All substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and procurement in regulated industries.

Packaging and Distribution: The three substitute parts differ in packaging configuration:

• AD8058ARMZ: Tube packaging
• AD8058ARMZ-REEL: Standard reel packaging
• AD8058ARMZ-REEL7: Cut Tape and Digi-Reel packaging

Selection between these variants depends on procurement volume and distribution requirements. All three maintain identical electrical specifications and mechanical compatibility.

Performance Enhancement: The AD8058 series substitute parts provide improved electrical performance compared to the MAX4387EUA, including higher slew rate (1150 V/µs vs. 385 V/µs), greater bandwidth (325 MHz vs. 130 MHz), and lower input bias current (500 nA vs. 13 µA). These enhancements do not compromise backward compatibility in applications designed for the MAX4387EUA.

Frequently Asked Questions (FAQ)

Q: Can AD8058ARMZ, AD8058ARMZ-REEL, and AD8058ARMZ-REEL7 be used interchangeably as substitutes for MAX4387EUA?

A: Yes. All three parts are functionally equivalent substitutes. They differ only in packaging format (tube, reel, or cut tape/Digi-Reel). Selection depends on procurement volume and distribution method. Electrical specifications and mechanical compatibility are identical across all three variants.

Q: What are the key compatibility factors for substituting MAX4387EUA with AD8058 series parts?

A: Compatibility is ensured through: identical 8-MSOP surface mount package dimensions (0.118" width, 3.00mm), dual-circuit configuration, matching operating temperature range (-40°C to 85°C), compatible supply voltage operation, and equivalent amplifier functionality. All substitute parts are pin-compatible and require no PCB redesign.

Q: How do the electrical specifications of AD8058 series parts compare to MAX4387EUA?

A: AD8058 series parts provide superior performance: slew rate of 1150 V/µs (vs. 385 V/µs), -3dB bandwidth of 325 MHz (vs. 130 MHz), input bias current of 500 nA (vs. 13 µA), and lower supply current of 14 mA (vs. 23 mA). These improvements enhance circuit performance without affecting backward compatibility.

Q: Is the higher supply voltage range of AD8058 series parts (3 V to 12 V vs. 2.85 V to 6.5 V) a concern for existing MAX4387EUA designs?

A: No. The AD8058 series supply voltage range encompasses the MAX4387EUA range. Designs operating within the original 2.85 V to 6.5 V specification will function identically with AD8058 substitutes. The extended upper limit (12 V) provides additional design flexibility without affecting existing applications.

Q: What is the significance of RoHS3 compliance in AD8058 series parts compared to the non-compliant MAX4387EUA?

A: RoHS3 compliance indicates adherence to current environmental and hazardous substance restrictions. For new designs, procurement in regulated markets, or applications subject to environmental standards, ROHS3-compliant AD8058 series parts are required. Existing MAX4387EUA designs can transition to compliant substitutes without functional impact.

Q: Are there any circuit design modifications required when substituting MAX4387EUA with AD8058 series parts?

A: No circuit modifications are required. AD8058 series parts are pin-compatible drop-in replacements. PCB layout, component placement, and signal routing remain unchanged. The improved electrical performance of AD8058 series parts may enhance overall circuit performance without requiring design alterations.
