Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX520ACWE are determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish substitution validity:

• Resolution and Channel Count: 8-bit resolution with 4 independent D/A converters
• Interface Protocol: I2C data interface
• Supply Voltages: 5V analog and digital supply
• Accuracy Specifications: INL/DNL of ±1 LSB (Max)
• Settling Time: 2µs typical
• Package Configuration: 16-SOIC surface mount package with 0.295" (7.50mm) width
• Architecture: R-2R converter topology
• Temperature Range: 0°C to 70°C operating specification

Parts meeting all these parameters are classified as direct substitutes. Variations in product status or compliance certifications do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both MAX520ACWE+ and MAX520BCWE+ are electrically and mechanically equivalent to the MAX520ACWE and function as direct substitutes in all applications requiring 8-bit, 4-channel DAC functionality with I2C interface and 5V supply operation.

MAX520ACWE+ is the preferred substitute for new designs and ongoing production. This part maintains active product status and carries ROHS3 compliance certification, ensuring alignment with current environmental and regulatory standards.

MAX520BCWE+ is an alternative substitute with identical electrical specifications and active product status. This part also carries ROHS3 compliance certification and is suitable for applications where supply availability or procurement requirements favor this variant.

The original MAX520ACWE, classified as obsolete, should be replaced with either active substitute in new procurement activities. Both substitutes are available in tube packaging and maintain full parametric compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can MAX520ACWE+ and MAX520BCWE+ be used interchangeably with MAX520ACWE?

A: Yes. All three parts share identical electrical specifications, pin configurations, and package dimensions. They are direct substitutes with no circuit modifications required.

Q: What is the difference between MAX520ACWE and MAX520ACWE+?

A: The primary differences are product status and compliance certification. MAX520ACWE is obsolete and RoHS non-compliant, while MAX520ACWE+ is active and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there differences between MAX520ACWE+ and MAX520BCWE+?

A: Both parts are electrically and mechanically equivalent. The letter designation (A vs. B) indicates different temperature or performance grades within the MAX520 family, but both variants specified here operate identically across all provided parameters.

Q: What packaging options are available for substitute parts?

A: Both MAX520ACWE+ and MAX520BCWE+ are supplied in tube packaging. The 16-SOIC surface mount package remains consistent across all variants.

Q: Are there any compliance or certification differences between the substitutes?

A: Both MAX520ACWE+ and MAX520BCWE+ carry ROHS3 compliance and REACH Unaffected status. The original MAX520ACWE is RoHS non-compliant. For applications requiring environmental compliance, either active substitute is appropriate.

Q: Can these parts be soldered using standard reflow processes?

A: Yes. All parts use identical 16-SOIC surface mount packaging compatible with standard PCB assembly processes. Moisture sensitivity level (MSL) is 1 (Unlimited) for all variants, indicating no special moisture control requirements during storage or handling.
