MAX4266ESA Equivalent & Substitute Parts

Part Overview

The MAX4266ESA is a voltage feedback amplifier manufactured by Analog Devices Inc./Maxim Integrated, designed for high-speed signal conditioning applications. This device integrates one amplifier circuit in an 8-SOIC surface mount package and delivers a gain bandwidth product of 700 MHz with a slew rate of 900V/µs.

The MAX4266ESA is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, system maintenance, and design continuity where this component is specified in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4266ESA is determined by strict alignment of the following electrical and mechanical parameters:

Mechanical Compatibility:

• Package type: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Mounting type: Surface mount

Functional Compatibility:

• Amplifier topology: Voltage feedback configuration
• Circuit count: Single amplifier circuit per package
• Operating temperature range: -40°C to 85°C minimum

Electrical Operating Range:

• Supply voltage span must encompass or exceed the original specification (4.5V to 8V minimum)
• Output current capability must meet or exceed 100 mA per channel

The THS4275D from Texas Instruments satisfies all mechanical and functional compatibility criteria. The substitute part operates within the required temperature range, maintains the same package footprint, and provides equivalent or superior electrical performance in the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MAX4266ESA is classified as obsolete, making long-term availability uncertain. The THS4275D is in active production status, ensuring continued supply and support.

Compliance and Certification: The THS4275D holds ROHS3 compliance, whereas the MAX4266ESA is RoHS non-compliant. Both parts are REACH Unaffected and carry EAR99 ECCN classification. For applications subject to RoHS requirements, the THS4275D is the appropriate selection.

Electrical Performance: The THS4275D provides superior output current capability (160 mA versus 100 mA) and extended supply voltage range (5V to 15V versus 4.5V to 8V). The substitute part operates at lower supply current (22 mA versus 28 mA), reducing power consumption. These characteristics make the THS4275D suitable for applications requiring higher output drive capability or extended supply flexibility.

Package and Thermal Compatibility: Both parts utilize identical 8-SOIC surface mount packaging with matching footprints and pinouts, enabling direct board-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the THS4275D be used as a direct replacement for the MAX4266ESA in existing designs?

A: Yes. Both devices share identical package geometry (8-SOIC, 0.154" width), pinout configuration, and voltage feedback amplifier topology. Direct substitution is mechanically and functionally compatible at the board level.

Q: What are the key electrical differences between these parts?

A: The THS4275D provides higher output current (160 mA versus 100 mA), extended supply voltage range (5V to 15V versus 4.5V to 8V), and lower supply current consumption (22 mA versus 28 mA). Input bias current and input offset voltage are slightly higher in the THS4275D. The -3dB bandwidth specification differs significantly (1400 MHz versus 350 MHz), reflecting different measurement or specification methodologies between manufacturers.

Q: Are there any compliance or regulatory differences?

A: The THS4275D is ROHS3 compliant, while the MAX4266ESA is RoHS non-compliant. Both parts are REACH Unaffected. For applications subject to RoHS directives, the THS4275D is the required selection.

Q: Why is the MAX4266ESA obsolete?

A: Obsolescence is determined by the original manufacturer. The THS4275D, as an active product from Texas Instruments, provides a viable path for design continuity and production support.

Q: Does substitution require circuit redesign?

A: No circuit redesign is required for basic substitution. The extended supply voltage range and higher output current of the THS4275D provide additional design margin. Applications operating within the original MAX4266ESA specifications will function identically with the substitute part.

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

A: Both the MAX4266ESA and THS4275D carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage or handling.
