• Output Configuration: Current-mode unbuffered output
• Interface Protocol: SPI digital communication
• Package Type: 16-TSSOP surface mount form factor
• Supply Voltage Range: Compatibility with 2.7V to 5.5V operation
• Settling Time: 500ns typical response time
• Reference Architecture: External reference requirement
• Accuracy Specification: ±1 LSB maximum INL/DNL

The AD5555CRUZ from Analog Devices Inc. meets all mandatory substitution criteria, providing equivalent functional performance within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The AD5555CRUZ is a qualified substitute for the DAC8802IPWRG4 based on the following engineering criteria:

Functional Equivalence: Both devices provide 14-bit dual-channel D/A conversion with SPI interface, identical settling time, and matching accuracy specifications (±1 LSB INL/DNL).

Package Compatibility: Both components utilize the 16-TSSOP surface mount package, enabling direct PCB layout compatibility without redesign.

Supply Voltage Consideration: The AD5555CRUZ operates at a fixed 5V supply, whereas the DAC8802IPWRG4 supports a wider range (2.7V ~ 5.5V). Applications requiring operation below 5V or with variable supply voltages must implement appropriate voltage regulation or consider alternative substitutes.

Regulatory Compliance: Both parts maintain ROHS3 compliance and equivalent environmental certifications (REACH Unaffected, EAR99 classification).

Product Availability: The AD5555CRUZ is actively manufactured by Analog Devices Inc., ensuring long-term supply continuity compared to the discontinued DAC8802IPWRG4.

Architecture Difference: The DAC8802IPWRG4 employs a multiplying DAC architecture, while the AD5555CRUZ uses R-2R topology. Both architectures deliver equivalent performance within the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the AD5555CRUZ directly replace the DAC8802IPWRG4 in all applications?

A: Direct replacement is possible for applications operating at 5V supply voltage. Applications requiring operation below 5V or with variable supply voltages require voltage regulation or alternative component selection.

Q: Are the SPI interface protocols identical between these devices?

A: Both devices implement SPI digital communication. Detailed protocol verification against specific application firmware is required during integration.

Q: What is the difference between multiplying DAC and R-2R architecture?

A: Both architectures achieve equivalent performance specifications for this application. The multiplying DAC (DAC8802IPWRG4) and R-2R topology (AD5555CRUZ) differ in internal implementation but deliver identical settling time, resolution, and accuracy within the specified parameters.

Q: Is the 16-TSSOP package identical for both parts?

A: Yes, both components use the 16-TSSOP (0.173", 4.40mm Width) surface mount package, enabling direct PCB footprint compatibility.

Q: What inventory status should be considered for procurement?

A: The AD5555CRUZ is actively manufactured with current inventory availability. The DAC8802IPWRG4 is discontinued and subject to limited remaining stock.
