AD5552BRZ Equivalent & Substitute Parts

Part Overview

The AD5552BRZ is a 14-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc., designed for data acquisition applications requiring voltage output conversion. This single-channel DAC operates with external reference voltage and communicates via SPI interface. The part is currently in active production status with 1405 units available in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD5552BRZ are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine substitution eligibility:

• Resolution: 14 bits (exact match required)
• Number of Converters: 1 channel (exact match required)
• Output Type: Voltage - Unbuffered (exact match required)
• Data Interface: SPI (exact match required)
• Reference Type: External (exact match required)
• INL/DNL Specification: ±0.15 LSB / ±0.15 LSB (exact match required)
• Architecture: R-2R (exact match required)
• Package: 14-SOIC form factor (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The identified substitutes (MAX545BESD+ and MAX545BESD+T) meet all electrical specifications and mechanical requirements. The primary difference is packaging format: MAX545BESD+ is supplied in Tube packaging, while MAX545BESD+T is supplied in Tape & Reel format. Both variants are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical performance.

Parameter Comparison

Engineering Selection Recommendations

All three parts (AD5552BRZ, MAX545BESD+, and MAX545BESD+T) are active production components with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

Supply Chain Considerations: MAX545BESD+ and MAX545BESD+T offer higher inventory availability (3100 and 2443 units respectively) compared to AD5552BRZ (1405 units).

Packaging Requirements: Choose MAX545BESD+ for tube packaging applications or MAX545BESD+T for tape and reel format requirements in automated assembly processes.

Supply Voltage Specifications: The AD5552BRZ supports a wider analog and digital supply voltage range (2.7V ~ 5.5V) compared to MAX545 variants (5V fixed). Applications requiring supply voltage flexibility below 5V must use AD5552BRZ.

Regulatory Compliance: All parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can MAX545BESD+ directly replace AD5552BRZ in existing designs?

A: Direct replacement is possible only if the design operates at 5V supply voltage. The AD5552BRZ supports 2.7V ~ 5.5V supply range, while MAX545BESD+ operates at fixed 5V. Verify supply voltage requirements before substitution.

Q: What is the difference between MAX545BESD+ and MAX545BESD+T?

A: Both parts are electrically identical. The difference is packaging format: MAX545BESD+ is supplied in Tube packaging, while MAX545BESD+T is supplied in Tape & Reel format. Selection depends on assembly process requirements.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 14-SOIC package with identical pinout and mechanical dimensions (0.154", 3.90mm width).

Q: Do these parts require design changes when substituting?

A: No design changes are required for electrical substitution when supply voltage is 5V. The SPI interface, external reference configuration, and output characteristics are identical across all three parts.

Q: What certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN classification is EAR99 for all variants.
