Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX5441ACUA are identified based on strict electrical and mechanical parameter matching within the data acquisition DAC category. The substitution logic is based on the following critical parameters:

• 16-bit resolution requirement
• Single D/A converter configuration
• Voltage output, unbuffered topology
• SPI digital interface
• External reference architecture
• R-2R converter architecture
• 5V dual supply operation
• ±0.5 LSB INL/DNL specification
• 8-pin TSSOP/MSOP surface mount package
• 0°C to 70°C operating temperature range

Parts meeting all these electrical and mechanical criteria are classified as direct substitutes. Variations in product status and compliance certifications do not affect functional substitutability when all specified parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

Both MAX5441ACUA+ and MAX5441BCUA+ are functionally equivalent to the MAX5441ACUA across all specified electrical and mechanical parameters. Selection between these substitutes should be based on the following factors:

MAX5441ACUA+ is the direct product line continuation of the obsolete MAX5441ACUA. This part maintains identical specifications and is classified as active product status, ensuring long-term availability and supply chain support. The part is ROHS3 compliant and supplied in tube packaging.

MAX5441BCUA+ is a parametric equivalent offering identical electrical performance and package configuration. This part is also active product status and ROHS3 compliant, supplied in tube packaging. The "B" grade designation indicates equivalent performance characteristics within the specified parameter ranges.

Both substitutes are suitable for direct replacement in applications currently using the MAX5441ACUA, provided that system design accommodates the 8-pin TSSOP/MSOP surface mount package and 5V dual supply operation.

Frequently Asked Questions (FAQ)

Q: Can MAX5441ACUA+ and MAX5441BCUA+ be used interchangeably with MAX5441ACUA?

A: Yes. All three parts share identical electrical specifications including 16-bit resolution, 1µs settling time, ±0.5 LSB INL/DNL, R-2R architecture, SPI interface, and external reference configuration. They are housed in the same 8-pin TSSOP/MSOP package and operate from identical 5V dual supplies across the 0°C to 70°C temperature range.

Q: What is the difference between MAX5441ACUA+ and MAX5441BCUA+?

A: Both parts are functionally equivalent. The primary difference is the grade designation: "A" and "B" indicate different performance grades within the same parametric specification range. Both meet the ±0.5 LSB INL/DNL requirement and are active product status with ROHS3 compliance.

Q: Why is the original MAX5441ACUA classified as obsolete?

A: The MAX5441ACUA is listed as obsolete product status. The active equivalents MAX5441ACUA+ and MAX5441BCUA+ provide continued access to this DAC topology with improved compliance status (ROHS3 compliant versus RoHS non-compliant).

Q: Are there any package or mounting differences between these parts?

A: No. All three parts use the 8-pin TSSOP/MSOP surface mount package with 0.118" width (3.00mm). Mounting type and PCB footprint are identical across all variants.

Q: What supply voltages are required for operation?

A: All three parts require dual 5V supplies: 5V for analog supply and 5V for digital supply. Operating temperature range is 0°C to 70°C for all variants.

Q: Are these parts RoHS compliant?

A: The original MAX5441ACUA is RoHS non-compliant. Both substitute parts MAX5441ACUA+ and MAX5441BCUA+ are ROHS3 compliant, meeting current environmental and regulatory requirements.
