Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX521BCPP is determined by strict equivalence across the following critical parameters:

• Resolution & Converter Count: 8-bit resolution with 8 independent D/A converters
• Output Configuration: Buffered voltage output with external reference
• Interface Protocol: I2C data interface
• Electrical Performance: Settling time of 6µs (Typ), INL/DNL specifications of ±2 (Max) and ±1 (Max)
• Supply Voltage: Dual 5V supplies (analog and digital)
• Architecture: R-2R converter architecture
• Package: 20-DIP through-hole package with 0.300" (7.62mm) pitch
• Temperature Range: 0°C to 70°C operating range

The MAX521BCPP+ meets all these criteria and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAX521BCPP+ is the direct functional equivalent of the MAX521BCPP and is suitable for replacement in all applications requiring an 8-bit, 8-channel buffered voltage output DAC with I2C interface and 5V dual supply operation.

The primary distinction between these parts is product status and compliance certification. The MAX521BCPP is obsolete, while the MAX521BCPP+ maintains active production status. Additionally, the MAX521BCPP+ achieves ROHS3 compliance, whereas the original MAX521BCPP is RoHS non-compliant. For new designs or systems requiring regulatory compliance with modern environmental standards, the MAX521BCPP+ is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part provides identical electrical and functional performance.

Frequently Asked Questions (FAQ)

Q: Can the MAX521BCPP+ be used as a direct replacement for the MAX521BCPP?

A: Yes. The MAX521BCPP+ is electrically and functionally identical to the MAX521BCPP across all critical parameters including resolution, converter count, output type, interface protocol, settling time, supply voltages, and package configuration. Pin-for-pin compatibility and identical PCB footprint requirements are maintained.

Q: What is the primary reason to transition from MAX521BCPP to MAX521BCPP+?

A: The MAX521BCPP is classified as obsolete, creating supply chain risk for ongoing production and maintenance. The MAX521BCPP+ is in active production status, ensuring continued availability. Additionally, the MAX521BCPP+ meets ROHS3 compliance requirements, whereas the original part does not.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts share identical electrical specifications including 8-bit resolution, 6µs settling time, ±2/±1 LSB INL/DNL performance, R-2R architecture, and 0°C to 70°C operating temperature range.

Q: What packaging options are available?

A: The MAX521BCPP+ is supplied in Tube packaging. Both parts utilize the 20-DIP through-hole package with 0.300" (7.62mm) pitch.

Q: Are there any application limitations when substituting the MAX521BCPP with MAX521BCPP+?

A: No application limitations exist. The parts are functionally equivalent across all specified parameters. System design, PCB layout, and application firmware require no modification for substitution.
