MAX965ESA Equivalent & Substitute Parts

Part Overview

The MAX965ESA is a single-channel comparator with integrated voltage reference, featuring open-drain and rail-to-rail output configuration in an 8-SOIC surface mount package. Manufactured by Analog Devices Inc./Maxim Integrated, this device operates across a 1.6V to 5.5V supply range with low input offset voltage and minimal quiescent current consumption.

The MAX965ESA is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this comparator.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX965ESA are identified based on the following critical parameters:

Packaging Compatibility: All substitutes must use the 8-SOIC surface mount package to ensure direct PCB footprint compatibility without layout modifications.

Electrical Interface: Substitutes must operate within overlapping supply voltage ranges and maintain comparable input/output electrical characteristics to function in existing circuit topologies.

Functional Classification: The MAX965ESA is a comparator with integrated voltage reference. Substitutes are grouped by their functional type and output configuration, as these determine circuit behavior and application suitability.

Compliance Requirements: All substitutes must maintain ROHS3 compliance and equivalent regulatory certifications to meet procurement and environmental standards.

The substitution logic recognizes that direct pin-for-pin equivalents may not exist due to the obsolete status of the original part. Substitutes are therefore evaluated on functional equivalence within the 8-SOIC package constraint.

Parameter Comparison

Engineering Selection Recommendations

MAX965ESA+ (Direct Successor): This part is the active production equivalent of the MAX965ESA, manufactured by the same supplier with identical electrical specifications and packaging. The MAX965ESA+ maintains the same voltage reference architecture, open-drain output configuration, and supply voltage range. Selection of MAX965ESA+ eliminates obsolescence risk while preserving circuit design without modification. This part is ROHS3 compliant and currently in active production status.

TS3022IDT (Functional Alternative): The TS3022IDT is a general-purpose dual comparator manufactured by STMicroelectronics in the same 8-SOIC package. This part differs functionally as a general-purpose comparator without integrated voltage reference and features push-pull output rather than open-drain configuration. The TS3022IDT operates within a 1.8V to 5V supply range and exhibits significantly faster propagation delay (105ns versus 20µs). Selection of TS3022IDT requires circuit redesign to accommodate the absence of integrated voltage reference and the different output stage topology. This part is ROHS3 compliant and in active production status.

For applications requiring direct functional replacement without circuit modification, MAX965ESA+ is the appropriate selection. For applications where circuit redesign is feasible and faster response time is beneficial, TS3022IDT provides an alternative in the same package footprint.

Frequently Asked Questions (FAQ)

Q: Can MAX965ESA+ be used as a direct replacement for MAX965ESA?

A: Yes. MAX965ESA+ is manufactured by Analog Devices Inc./Maxim Integrated with identical electrical specifications, package configuration, and functional characteristics. No circuit modifications are required. The primary difference is product status: MAX965ESA is obsolete while MAX965ESA+ is in active production.

Q: What are the key differences between MAX965ESA and TS3022IDT?

A: The MAX965ESA is a single-channel comparator with integrated voltage reference and open-drain output. The TS3022IDT is a dual-channel general-purpose comparator with push-pull output and no integrated voltage reference. The TS3022IDT operates at 1.8V to 5V (versus 1.6V to 5.5V for MAX965ESA) and has significantly faster propagation delay (105ns versus 20µs). Circuit redesign is required to use TS3022IDT as a substitute.

Q: Are all substitute parts available in the same 8-SOIC package?

A: Yes. MAX965ESA+, MAX965ESA, and TS3022IDT are all available in 8-SOIC (0.154", 3.90mm Width) surface mount packages, ensuring PCB footprint compatibility.

Q: Do all parts meet the same compliance standards?

A: Yes. MAX965ESA, MAX965ESA+, and TS3022IDT are all ROHS3 compliant with REACH Unaffected status and EAR99 ECCN classification.

Q: Which substitute should be selected for new designs?

A: For new designs requiring the functional characteristics of the original MAX965ESA, MAX965ESA+ is the appropriate selection as it is in active production status. For applications where integrated voltage reference is not required and faster response time is beneficial, TS3022IDT provides an alternative.

Q: What is the operating temperature range difference between MAX965ESA and TS3022IDT?

A: MAX965ESA operates from -40°C to 85°C. TS3022IDT operates from -40°C to 125°C, providing extended high-temperature capability.
