Substitute Part Grouping Explanation

Substitution of the MAX968EUA is determined by strict equivalence across the following critical parameters:

• Comparator Type: Dual-channel window comparator configuration
• Output Configuration: Open-drain and push-pull output stages
• Supply Voltage Compatibility: 1.6V to 5.5V single/dual supply operation
• Electrical Performance: Input offset voltage, input bias current, quiescent current, CMRR, PSRR, propagation delay, and hysteresis specifications
• Package Compatibility: 8-TSSOP/8-MSOP surface mount form factor with 0.118" (3.00mm) width
• Environmental & Compliance: Operating temperature range -40°C to 85°C, RoHS3 compliance, MSL 1 rating

The MAX968EUA+ qualifies as a direct substitute based on identical electrical specifications, package form factor, and compliance certifications. The primary distinction is product status and output stage configuration variance.

Parameter Comparison

Engineering Selection Recommendations

The MAX968EUA+ is the direct substitute for the obsolete MAX968EUA. Both parts maintain identical electrical performance specifications, package form factor, and compliance certifications. The MAX968EUA+ is currently in active production status, ensuring long-term availability and supply chain continuity.

The output stage configuration differs between the two parts: the MAX968EUA features open-drain and push-pull outputs, while the MAX968EUA+ features open-drain and rail-to-rail outputs. This distinction does not affect functional substitution in applications where the output stage characteristics are compatible with the circuit design.

Input bias current specification shows a variance: the MAX968EUA specifies 0.005µA maximum at 5.5V, while the MAX968EUA+ specifies 0.05µA maximum at 5.5V. This represents a 10-fold increase in maximum input bias current and must be evaluated against circuit-level requirements for input impedance and bias current compensation.

Both parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, supporting deployment in standard manufacturing environments without additional moisture control measures.

Frequently Asked Questions (FAQ)

Q: Can MAX968EUA+ directly replace MAX968EUA in existing designs?

A: The MAX968EUA+ is functionally equivalent to the MAX968EUA across all critical window comparator specifications including supply voltage range, input offset voltage, quiescent current, propagation delay, and hysteresis. Both parts use identical 8-TSSOP/8-MSOP packaging. Substitution is valid provided the circuit design accommodates the output stage configuration and input bias current specifications of the MAX968EUA+.

Q: What is the significance of the output stage difference between these parts?

A: The MAX968EUA features open-drain and push-pull outputs, while the MAX968EUA+ features open-drain and rail-to-rail outputs. The rail-to-rail output stage in the MAX968EUA+ provides output swing capability closer to the supply rails. Circuit designs must be evaluated to confirm compatibility with the specific output stage characteristics required by the application.

Q: How does the input bias current difference affect circuit design?

A: The MAX968EUA specifies maximum input bias current of 0.005µA at 5.5V, while the MAX968EUA+ specifies 0.1µA maximum at 5.5V. Applications with high-impedance input sources or precision analog signal conditioning may require bias current compensation. Circuit designs should be reviewed to confirm the MAX968EUA+ input bias current specification is acceptable for the intended application.

Q: Are both parts available in the same packaging options?

A: Both the MAX968EUA and MAX968EUA+ are supplied in 8-TSSOP and 8-MSOP surface mount packages with 0.118" (3.00mm) width. Pin configuration and PCB footprint compatibility are identical between the two parts.

Q: What is the product status difference and why does it matter?

A: The MAX968EUA is classified as obsolete, indicating it is no longer in active production. The MAX968EUA+ is in active production status, ensuring continued availability, manufacturing support, and compliance with current industry standards. For new designs and long-term supply chain planning, the MAX968EUA+ is the recommended selection.

Q: Do both parts meet the same compliance and environmental standards?

A: Both the MAX968EUA and MAX968EUA+ are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity rating. Both parts operate across the -40°C to 85°C temperature range. Compliance certifications are equivalent between the two parts.
