MAX4267EUA-T Equivalent & Substitute Parts

Part Overview

The MAX4267EUA-T is a voltage feedback amplifier manufactured by Analog Devices Inc./Maxim Integrated, designed as a single-circuit operational amplifier in an 8-uMAX/uSOP surface mount package. This device is classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing design support, production continuity, and system maintenance.

The MAX4267EUA-T delivers high-speed amplification with a 1.5 GHz gain bandwidth product and 900 V/µs slew rate, suitable for applications requiring precision voltage feedback amplification in compact form factors. Due to its obsolete status, equivalent active components must be evaluated to maintain design functionality and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4267EUA-T is determined by strict equivalence across the following critical parameters:

Functional Architecture: Both the main part and substitute must operate as single-circuit voltage feedback amplifiers with surface mount packaging compatible with 8-pin TSSOP/MSOP footprints.

Electrical Performance Boundaries: Substitute components must maintain voltage feedback amplification topology. Key performance metrics including slew rate, gain bandwidth product, input bias current, input offset voltage, output current capability, and supply voltage range define the operational envelope. Substitutes must support the same operating temperature range (-40°C to 85°C).

Compliance & Regulatory: Both components must maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status to ensure regulatory alignment and manufacturing compatibility.

Supply Voltage Compatibility: The substitute must operate within or exceed the supply voltage span of the original part (4.5 V to 8 V minimum requirement).

The THS4275DGN from Texas Instruments qualifies as a manufacturer-recommended substitute based on these criteria, with enhanced performance specifications in certain parameters while maintaining functional equivalence in the voltage feedback amplifier category.
