MAX5264ACMH Equivalent & Substitute Parts

Part Overview

The MAX5264ACMH is a 14-bit digital-to-analog converter (DAC) with 8 channels and voltage-buffered output, manufactured by Analog Devices Inc./Maxim Integrated. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system support and new designs. The part operates with external voltage references and parallel data interfaces, serving applications requiring multi-channel analog signal generation in industrial and instrumentation systems.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX5264ACMH are qualified based on the following critical parameters:

• Resolution & Channel Count: 14-bit resolution with 8 D/A converters (non-negotiable for functional equivalence)
• Output Configuration: Voltage-buffered output with external reference requirement
• Data Interface: Parallel interface architecture
• Package Compatibility: 44-QFP (10x10) surface mount package
• Electrical Architecture: R-2R converter topology
• Compliance: ROHS3 certification for environmental standards

The AD7841 series (AD7841ASZ, AD7841ASZ-REEL, AD7841BSZ) meets all substitution criteria. These parts maintain identical resolution, channel count, output type, data interface, and package specifications. All substitute parts are in active product status with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: AD7841BSZ

The AD7841BSZ is the preferred substitute for the MAX5264ACMH. This part maintains full functional equivalence across all critical parameters while offering superior INL/DNL specifications (±2 Max / ±1 Max versus ±4 Max / ±1 Max on the original). The extended operating temperature range (-40°C to 85°C) provides broader environmental coverage compared to the MAX5264ACMH (0°C to 70°C). AD7841BSZ is in active production status with ROHS3 compliance and REACH unaffected certification, ensuring long-term supply chain stability and regulatory compliance.

Secondary Recommendation: AD7841ASZ or AD7841ASZ-REEL

Both AD7841ASZ variants provide functional substitution with identical core specifications. The primary distinction is packaging format: AD7841ASZ is supplied in trays, while AD7841ASZ-REEL is supplied in tape and reel format. Selection between these variants depends on assembly process requirements and volume considerations. Both maintain active product status and full compliance certifications.

Substitution Constraints: All substitute parts exhibit a 9µs increase in settling time (31µs versus 22µs). Applications with timing-critical analog signal generation must account for this performance difference in system design.

Frequently Asked Questions (FAQ)

Q: Can AD7841 series parts directly replace MAX5264ACMH in existing designs?

A: Yes, with one consideration. The AD7841 series maintains identical resolution (14-bit), channel count (8), output type (voltage-buffered), data interface (parallel), package (44-QFP), and mounting type (surface mount). The primary difference is settling time: AD7841 parts settle in 31µs versus 22µs for the MAX5264ACMH. Designs with timing margins can accommodate this difference without modification. Designs with tight timing constraints require validation.

Q: What is the difference between AD7841ASZ, AD7841ASZ-REEL, and AD7841BSZ?

A: AD7841ASZ and AD7841ASZ-REEL are identical parts with different packaging formats (tray versus tape & reel). AD7841BSZ differs in INL/DNL specifications: ±2 Max / ±1 Max versus ±4 Max / -0.9/+2 Max for the ASZ variants. AD7841BSZ provides tighter linearity performance and is the recommended choice for applications requiring superior accuracy.

Q: Are there supply chain differences between substitute options?

A: All three AD7841 variants are in active production. AD7841BSZ has the highest current inventory (1,728 pcs), followed by AD7841ASZ (1,204 pcs) and AD7841ASZ-REEL (1,107 pcs). For high-volume requirements, AD7841BSZ offers the best availability.

Q: Do substitute parts require PCB layout modifications?

A: No. All substitute parts use the identical 44-MQFP (10x10) package with surface mount configuration. PCB footprints, pin assignments, and layout requirements remain unchanged.

Q: What compliance certifications apply to substitute parts?

A: All AD7841 variants are ROHS3 compliant. AD7841ASZ and AD7841ASZ-REEL carry REACH unaffected certification. All parts are classified under ECCN EAR99 and HTSUS 8542.39.0001.
