MAX984ESE Equivalent & Substitute Parts

Part Overview

The MAX984ESE is a 4-channel comparator with integrated voltage reference manufactured by Analog Devices Inc./Maxim Integrated. This linear integrated circuit is housed in a 16-SOIC surface mount package and operates across a supply voltage range of 2.5V to 11V (single supply) or ±1.25V to 5.5V (dual supply). The device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX984ESE is determined by strict equivalence across the following critical parameters:

• Functional Type: 4-channel comparator with integrated voltage reference
• Supply Voltage Range: 2.5V ~ 11V (single supply) or ±1.25V ~ 5.5V (dual supply)
• Input Offset Voltage: 10mV @ 5V maximum
• Quiescent Current: 8.5µA maximum
• Common Mode Rejection Ratio (CMRR): 80dB typical
• Power Supply Rejection Ratio (PSRR): 80dB typical
• Operating Temperature Range: -40°C ~ 85°C
• Package: 16-SOIC surface mount
• Compliance: ROHS3 compliant, MSL Level 1

The substitute part must maintain identical electrical performance specifications and physical package dimensions to ensure direct replacement capability in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The MAX984ESE+ is the direct equivalent substitute for the obsolete MAX984ESE. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical specifications and physical packaging. The primary distinction is product status: the MAX984ESE is obsolete while the MAX984ESE+ is active and currently in production.

For new designs or production continuity, the MAX984ESE+ is the appropriate selection. Both parts carry ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing processes and long-term reliability. The active production status of the MAX984ESE+ guarantees availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can MAX984ESE+ directly replace MAX984ESE in existing designs?

A: Yes. The MAX984ESE+ is electrically and mechanically identical to the MAX984ESE. Both devices feature the same 4-channel comparator architecture, identical supply voltage ranges (2.5V ~ 11V single supply or ±1.25V ~ 5.5V dual supply), matching input offset voltage specifications (10mV @ 5V), and identical 16-SOIC package dimensions. Direct substitution is possible without circuit modification.

Q: What is the primary reason to transition from MAX984ESE to MAX984ESE+?

A: The MAX984ESE is classified as obsolete, meaning it is no longer in active production. The MAX984ESE+ is the active production equivalent, ensuring long-term availability, supply chain reliability, and manufacturer support. Transitioning to the MAX984ESE+ mitigates obsolescence risk for new designs and ongoing production.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the MAX984ESE and MAX984ESE+ carry identical compliance certifications: ROHS3 compliant and MSL Level 1 (Unlimited). Both parts meet the same environmental and regulatory standards.

Q: What is the significance of the "+" suffix in MAX984ESE+?

A: The "+" suffix indicates the active production variant of the base MAX984 comparator. It denotes the current manufacturing designation from Analog Devices Inc./Maxim Integrated and confirms active product status.

Q: Are there any package or mounting differences?

A: No. Both parts use identical 16-SOIC surface mount packaging with 0.154" (3.90mm) width. PCB footprints and reflow soldering profiles are identical.
