MAX968ESA+ Equivalent & Substitute Parts

Part Overview

The MAX968ESA+ is a window comparator IC manufactured by Analog Devices Inc./Maxim Integrated, designed for applications requiring dual-element comparison with open-drain, rail-to-rail output configuration. This device operates across a supply voltage range of 1.6V to 5.5V and is housed in an 8-SOIC surface mount package. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative components are evaluated based on matching electrical performance parameters, package compatibility, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX968ESA+ is the direct equivalent part. Selection is based on the following engineering criteria:

Product Status & Availability: The part maintains active production status, ensuring continued availability and supply chain stability for new designs and production runs.

Regulatory Compliance: ROHS3 compliance certifies conformance to European Union Restriction of Hazardous Substances directives. REACH unaffected status confirms no substance of very high concern (SVHC) restrictions apply. MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related reliability concerns.

Electrical Performance Verification: All specified electrical parameters—input offset voltage, bias current, quiescent current, CMRR, PSRR, propagation delay, and hysteresis—are met within stated tolerances. These parameters directly determine functional compatibility in window comparator applications.

Package & Thermal Considerations: The 8-SOIC surface mount package provides standard PCB integration. Operating temperature range of -40°C to 85°C covers industrial and commercial application requirements.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX968ESA+? A: A valid substitute must match all electrical parameters (input offset, bias current, quiescent current, CMRR, PSRR, propagation delay, hysteresis), operate within the 1.6V to 5.5V supply range, use open-drain rail-to-rail output architecture, maintain the 8-SOIC package form factor, and meet ROHS3 and REACH compliance requirements.

Q: Can the MAX968ESA+ be used in applications requiring different supply voltages? A: The MAX968ESA+ operates within the 1.6V to 5.5V supply voltage range. Applications requiring operation outside this range require alternative components with different voltage specifications.

Q: Is the 8-SOIC package interchangeable with other package types? A: No. The 8-SOIC package is specific to this device. Different package types (such as DIP or QFP variants) require separate component evaluation and PCB layout modifications.

Q: What is the significance of the ±1mV hysteresis specification? A: Hysteresis defines the voltage difference between upper and lower threshold levels in the window comparator. The ±1mV specification ensures stable switching behavior and noise immunity within the specified operating range.

Q: Does MSL 1 rating affect component handling or storage? A: MSL 1 indicates unlimited moisture sensitivity level, meaning the component has no moisture-related storage restrictions. Standard ESD precautions and dry storage conditions remain recommended for all semiconductor components.

Q: Are there performance differences between tube and other packaging formats for the MAX968ESA+? A: Tube packaging is a distribution format only. Electrical performance and functional characteristics remain identical regardless of packaging format (tube, tape and reel, or bulk). Component selection should be based on electrical specifications and application requirements, not packaging format.
