MAX545BESD+ Equivalent & Substitute Parts

Part Overview

The MAX545BESD+ is a 14-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring voltage output conversion. This component operates with 5V analog and digital supply voltages and features an external reference configuration with SPI data interface. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent parts may be required due to inventory constraints, supply chain considerations, or design flexibility needs for voltage supply range optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX545BESD+ is determined by strict equivalence across the following critical parameters:

• Resolution & Architecture: 14-bit resolution with R-2R architecture
• Functional Interface: Single D/A converter with SPI data interface and external reference configuration
• Output Characteristics: Voltage-unbuffered output with ±0.15 LSB INL/DNL specification
• Package & Mounting: 14-SOIC surface mount package with identical physical dimensions
• Operating Temperature: -40°C ~ 85°C range
• Compliance & Certifications: ROHS3 compliance, MSL 1 rating, REACH unaffected status

The AD5552BRZ qualifies as a manufacturer-recommended equivalent based on matching all functional and package specifications. The primary design difference is the expanded supply voltage range (2.7V ~ 5.5V for both analog and digital supplies versus fixed 5V), which provides additional flexibility while maintaining full backward compatibility with MAX545BESD+ applications.

Parameter Comparison

Engineering Selection Recommendations

Both MAX545BESD+ and AD5552BRZ maintain active product status with full ROHS3 compliance and identical MSL 1 ratings, confirming suitability for production applications. The AD5552BRZ offers extended supply voltage flexibility (2.7V ~ 5.5V range) compared to the MAX545BESD+ fixed 5V specification, enabling use in broader system architectures without functional compromise. Selection between these parts should be based on supply voltage requirements of the target application and component availability. Both parts satisfy identical electrical performance specifications and package requirements for direct substitution in 14-bit DAC applications requiring SPI interface and external reference configuration.

Frequently Asked Questions (FAQ)

Q: Can AD5552BRZ directly replace MAX545BESD+ in existing designs? A: Yes. Both parts share identical 14-bit resolution, R-2R architecture, SPI interface, external reference configuration, settling time, INL/DNL specifications, and 14-SOIC package dimensions. The AD5552BRZ's expanded supply voltage range (2.7V ~ 5.5V) is backward compatible with MAX545BESD+ 5V applications.

Q: What is the primary functional difference between these parts? A: The AD5552BRZ supports supply voltages from 2.7V to 5.5V for both analog and digital supplies, whereas the MAX545BESD+ requires fixed 5V supplies. All other electrical and functional parameters are equivalent.

Q: Are there any package or mounting differences? A: No. Both parts use identical 14-SOIC surface mount packages with 0.154" (3.90mm) width. PCB layout and footprints are interchangeable.

Q: Do both parts meet the same compliance standards? A: Yes. Both MAX545BESD+ and AD5552BRZ are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings.

Q: What operating temperature range applies to both parts? A: Both parts operate across -40°C to 85°C, suitable for industrial and commercial temperature environments.

Q: Can supply voltage differences affect circuit performance? A: No. When operating at 5V, both parts deliver identical electrical performance. The AD5552BRZ's extended range simply provides design flexibility for lower-voltage applications without performance degradation.
