MAX502ACWG Equivalent & Substitute Parts
Part Overview
The MAX502ACWG is a 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring voltage output conversion. This component features an external reference architecture with R-2R topology and operates across a ±11.4V to ±15.75V analog supply range. The MAX502ACWG is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation
Substitution eligibility for the MAX502ACWG is determined by the following critical parameters: 12-bit resolution, single D/A converter configuration, 5µs settling time, buffered voltage output, parallel data interface, R-2R architecture, ±11.4V to ±15.75V analog supply compatibility, and 24-SOIC surface mount packaging.
The substitute parts identified maintain these core electrical and mechanical specifications. Variations in reference type (external versus internal) and INL/DNL performance represent secondary differences that do not preclude functional substitution when system design accommodates the specific reference architecture employed.

Engineering Selection Recommendations
MAX502ACWG+ serves as the direct functional equivalent with identical electrical specifications and packaging. This part maintains external reference architecture and achieves superior INL/DNL performance (±0.75/±1 LSB) while offering active product status and ROHS3 compliance, eliminating obsolescence concerns associated with the original MAX502ACWG.
MAX507BCWG+ provides an alternative with internal reference architecture, eliminating the requirement for external reference circuitry. This configuration reduces component count and board space while maintaining 12-bit resolution, 5µs settling time, and identical packaging. The internal reference trades INL/DNL performance (±1/±1 LSB) for simplified system design. MAX507BCWG+ is actively manufactured and ROHS3 compliant.
Selection between MAX502ACWG+ and MAX507BCWG+ depends on system design requirements: external reference designs should transition to MAX502ACWG+; designs tolerating internal reference architecture benefit from MAX507BCWG+ simplification.
Frequently Asked Questions (FAQ)
Q: Can MAX502ACWG+ directly replace MAX502ACWG without circuit modification?
A: Yes. MAX502ACWG+ maintains identical electrical specifications, reference architecture, and 24-SOIC packaging. No circuit modifications are required for direct substitution.
Q: What is the primary difference between MAX502ACWG+ and MAX507BCWG+?
A: Reference architecture differs. MAX502ACWG+ employs external reference; MAX507BCWG+ incorporates internal reference. Both maintain 12-bit resolution, 5µs settling time, and identical packaging. Circuit design must accommodate the reference type employed.
Q: Are all substitute parts available in 24-SOIC packaging?
A: Yes. MAX502ACWG+, MAX507BCWG+, and the original MAX502ACWG are all supplied in 24-SOIC (0.295", 7.50mm Width) surface mount packaging with identical pinout compatibility.
Q: What compliance advantages do the substitute parts offer?
A: Both MAX502ACWG+ and MAX507BCWG+ achieve ROHS3 compliance, whereas the original MAX502ACWG is RoHS non-compliant. Both substitute parts carry active product status, ensuring long-term availability and manufacturing support.
Q: How do INL/DNL specifications affect substitution decisions?
A: MAX502ACWG+ achieves ±0.75/±1 LSB performance; MAX507BCWG+ achieves ±1/±1 LSB. Applications requiring superior linearity should specify MAX502ACWG+. Applications tolerating ±1 LSB performance may select MAX507BCWG+.
Q: Can MAX507BCWG+ be used in designs originally specified for MAX502ACWG?
A: Substitution is possible when system design accommodates internal reference architecture and ±1 LSB INL/DNL performance. External reference designs require circuit modification to eliminate external reference components.
