Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX526CENG is determined by the following critical parameters that must remain consistent:

• Resolution & Channel Count: 12-bit resolution with 4 independent D/A converters
• Output Characteristics: Voltage-buffered output with external reference
• Timing Performance: 3µs typical settling time
• Accuracy Specifications: INL/DNL of ±0.15, ±1 LSB (Max)
• Interface Architecture: Parallel data interface with R-2R architecture
• Package Compatibility: 24-DIP through-hole package (0.300", 7.62mm)
• Temperature Range: -40°C ~ 85°C operating specification

The MAX526CENG+ qualifies as a direct substitute based on identical performance in all critical electrical parameters and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX526CENG+ is the direct functional equivalent of the MAX526CENG. Both components share identical electrical performance specifications, settling time characteristics, and package geometry. The primary distinction is product lifecycle status: the MAX526CENG is obsolete while the MAX526CENG+ maintains active production status.

For new designs or system updates, the MAX526CENG+ is the appropriate selection. This part offers ROHS3 compliance, addressing regulatory requirements that the original MAX526CENG does not meet. Both components are manufactured by Analog Devices Inc./Maxim Integrated under the same base product number (MAX526), ensuring design continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can MAX526CENG+ be used as a direct replacement for MAX526CENG in existing designs?

A: Yes. The MAX526CENG+ provides identical electrical performance across all critical parameters: 12-bit resolution, 4-channel configuration, 3µs settling time, voltage-buffered output, and R-2R architecture. Package geometry and pinout are identical, supporting direct board-level substitution.

Q: What is the primary advantage of selecting MAX526CENG+ over MAX526CENG?

A: The MAX526CENG+ maintains active production status and carries ROHS3 compliance certification. The MAX526CENG is classified as obsolete, creating long-term supply and support risks.

Q: Are there any supply voltage differences between these parts?

A: The MAX526CENG+ specifies dual supply voltage ranges (-4.5V ~ -5.5V, 10.8V ~ 16.5V) for both analog and digital supplies. The MAX526CENG specifies analog supply as 10.8V ~ 16.5V, -5V. Both support the same operating voltage envelope for standard applications.

Q: Is the 24-DIP through-hole package still suitable for modern PCB designs?

A: Yes. The 24-DIP package remains compatible with through-hole assembly processes. Both parts use identical 0.300" (7.62mm) package dimensions, supporting direct integration into existing PCB layouts without modification.

Q: What certifications apply to both parts?

A: Both MAX526CENG and MAX526CENG+ carry REACH Unaffected status and EAR99 export classification. The MAX526CENG+ additionally meets ROHS3 compliance requirements. Both components have Moisture Sensitivity Level (MSL) of 1 (Unlimited).
