MAX967ESA Equivalent & Substitute Parts

Part Overview

The MAX967ESA is a dual-channel comparator with integrated voltage reference, manufactured by Analog Devices Inc./Maxim Integrated. This device features open-drain, rail-to-rail output configuration in an 8-SOIC surface mount package. The MAX967ESA is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. Substitute parts maintain functional compatibility through matching electrical specifications and identical package geometry.

Engineering Selection Recommendations

MAX967ESA+ (Direct Substitute): The MAX967ESA+ is the primary substitute for the obsolete MAX967ESA. This part maintains identical electrical specifications, package configuration, and element count. The MAX967ESA+ carries active product status, ensuring long-term availability and manufacturing support. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The transition from MAX967ESA to MAX967ESA+ requires no circuit modifications.

MAX965ESA+ (Parametric Equivalent): The MAX965ESA+ is a parametric equivalent suitable for applications requiring single-channel comparator functionality. This part maintains identical electrical performance across all critical parameters except element count (1 comparator vs. 2) and quiescent current (12µA vs. 16µA). The MAX965ESA+ is active and fully compliant with RoHS3 and REACH requirements. Selection of MAX965ESA+ requires circuit redesign to accommodate single-channel operation and may reduce power consumption by 4µA in quiescent state.

Frequently Asked Questions (FAQ)

Q: Can MAX967ESA+ directly replace MAX967ESA without circuit modifications? A: Yes. The MAX967ESA+ maintains identical electrical specifications, package geometry, and element count. No circuit modifications are required for direct substitution.

Q: What is the primary difference between MAX967ESA+ and MAX965ESA+? A: The MAX967ESA+ contains two comparator elements, while MAX965ESA+ contains one. Both maintain identical electrical performance per comparator. The MAX965ESA+ has lower quiescent current (12µA vs. 16µA).

Q: Are all substitute parts available in the same package? A: Yes. MAX967ESA, MAX967ESA+, and MAX965ESA+ are all supplied in 8-SOIC (0.154", 3.90mm Width) surface mount packages with identical pin configurations for their respective element counts.

Q: Do substitute parts meet current compliance requirements? A: Yes. Both MAX967ESA+ and MAX965ESA+ are ROHS3 compliant and REACH unaffected, meeting current regulatory standards.

Q: What is the product status difference between the main part and substitutes? A: MAX967ESA is obsolete. MAX967ESA+ and MAX965ESA+ are both active products with ongoing manufacturing support and availability.

Q: Can MAX965ESA+ be used in applications designed for dual-channel operation? A: No. MAX965ESA+ provides single-channel functionality. Applications requiring dual-channel operation must use MAX967ESA+ or redesign the circuit to use two MAX965ESA+ devices.
