Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX525ACAP is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit
• Channel count: 4 independent D/A converters
• Output configuration: Voltage output with buffering
• Interface protocol: SPI
• Reference input: External reference
• Converter architecture: R-2R
• Supply voltages: 5V analog and digital
• Linearity specifications: INL/DNL ±0.25, ±1 (Max) LSB
• Settling time: 12µs typical
• Package: 20-SSOP surface mount
• Operating temperature range: 0°C ~ 70°C

Parts meeting all these parameters are classified as direct substitutes. Variations in any parameter disqualify a part from substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

The MAX525ACAP+ is a direct functional equivalent to the MAX525ACAP with identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance.

The MAX525ACAP is obsolete and carries RoHS non-compliant status. The MAX525ACAP+ is an active product meeting ROHS3 compliance requirements. For new designs or applications requiring regulatory compliance with modern environmental standards, the MAX525ACAP+ is the appropriate selection. Both parts share identical pinout, package footprint, and electrical performance characteristics, enabling direct substitution at the component level.

Frequently Asked Questions (FAQ)

Q: Can MAX525ACAP+ replace MAX525ACAP in existing designs?
