MAX5264ACMH-T Equivalent & Substitute Parts

Part Overview

The MAX5264ACMH-T is a 14-bit digital-to-analog converter (DAC) with 8 channels, voltage-buffered output, and parallel data interface, manufactured by Analog Devices Inc./Maxim Integrated. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The part is housed in a 44-MQFP (10x10) surface mount package and operates with external voltage reference configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5264ACMH-T is based on the following critical parameters that must remain consistent:

• 14-bit resolution with 8 D/A converter channels
• Voltage-buffered output configuration
• Parallel data interface with external voltage reference
• R-2R architecture
• 44-MQFP (10x10) surface mount package
• 5V digital supply voltage
• ROHS3 compliance and RoHS/REACH regulatory alignment

The AD7841 series (AD7841ASZ, AD7841ASZ-REEL, AD7841BSZ) from Analog Devices Inc. meets these core functional and physical requirements. These parts maintain identical bit resolution, channel count, output type, data interface, architecture, and package configuration. All substitute parts are active products with current manufacturing status, ensuring long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

All three AD7841 variants are active products with current manufacturing status, providing superior supply chain continuity compared to the obsolete MAX5264ACMH-T. Selection among the substitute parts depends on packaging and performance grade requirements:

AD7841ASZ (Tray Packaging): Standard production grade with ±4 LSB INL and -0.9/+2 LSB DNL specifications. Suitable for applications where tray packaging meets procurement and handling requirements.

AD7841ASZ-REEL (Tape & Reel Packaging): Identical electrical specifications to AD7841ASZ but supplied in tape and reel format, optimized for automated assembly and high-volume production environments.

AD7841BSZ (Tray Packaging): Enhanced performance grade with tighter INL/DNL specifications (±2 LSB INL, ±1 LSB DNL), matching the original MAX5264ACMH-T DNL tolerance. Recommended for applications requiring precision equivalent to the original component.

All substitute parts operate across an extended temperature range (-40°C to 85°C) compared to the original part (0°C to 70°C), providing additional operational margin. Analog supply voltage ranges differ between the original and substitutes; circuit design must accommodate the AD7841 series analog supply specification of ±14.6V ~ 16.5V.

Frequently Asked Questions (FAQ)

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

A: Direct pin-compatible replacement is supported for the 44-MQFP package footprint and 5V digital supply interface. However, analog supply voltage ranges differ. The MAX5264ACMH-T operates with 11.5V ~ 14V and -9V ~ 6.5V supplies, while AD7841 series requires ±14.6V ~ 16.5V. Circuit power supply design must be verified for compatibility before implementation.

Q: What is the difference between AD7841ASZ and AD7841BSZ?

A: Both parts are functionally equivalent 14-bit, 8-channel DACs in 44-MQFP packages with identical settling time (31µs). The primary difference is INL/DNL performance: AD7841ASZ specifies ±4 LSB INL and -0.9/+2 LSB DNL, while AD7841BSZ specifies ±2 LSB INL and ±1 LSB DNL. AD7841BSZ provides tighter linearity specifications matching the original MAX5264ACMH-T DNL tolerance.

Q: Why is AD7841ASZ-REEL listed separately from AD7841ASZ?

A: AD7841ASZ-REEL is the same die and electrical specification as AD7841ASZ but supplied in tape and reel packaging format instead of tray. Selection depends on assembly process requirements. Tape and reel format is standard for automated pick-and-place assembly, while tray packaging is used for manual handling or alternative assembly methods.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MAX5264ACMH-T, AD7841ASZ, AD7841ASZ-REEL, and AD7841BSZ are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the settling time difference between the original and substitute parts?

A: MAX5264ACMH-T specifies 22µs typical settling time, while all AD7841 variants specify 31µs typical settling time. This 9µs difference must be evaluated for applications with strict timing requirements. If the original 22µs specification is critical, circuit timing margins should be recalculated.

Q: How does moisture sensitivity differ between parts?

A: MAX5264ACMH-T has MSL 1 (unlimited moisture exposure), while AD7841 series has MSL 3 (168 hours maximum). MSL 3 requires controlled storage conditions and bake-out procedures before reflow soldering. Procurement and storage procedures must be updated accordingly.
