Key Parameters

Substitute Part Grouping Explanation

The AD5555CRUZ qualifies as a substitute for the DAC8802IPW based on the following matching parameters:

• 14-bit resolution with dual D/A converters
• 500ns typical settling time
• Current output, unbuffered configuration
• SPI digital interface
• External reference input
• ±1 LSB maximum INL/DNL specification
• -40°C to 85°C operating temperature range
• 16-TSSOP surface mount package with identical physical dimensions
• ROHS3 compliance and EAR99 export classification

Substitution is valid when these electrical and mechanical parameters are the controlling factors in component selection.

Parameter Comparison

Engineering Selection Recommendations

Both the DAC8802IPW and AD5555CRUZ are active production components with ROHS3 compliance and EAR99 export classification. The DAC8802IPW supports a wider analog and digital supply voltage range (2.7V to 5.5V) compared to the AD5555CRUZ fixed 5V requirement. The AD5555CRUZ offers superior moisture sensitivity rating (MSL 1 vs MSL 2), providing extended shelf life without baking requirements. Selection between these parts should be based on the specific supply voltage requirements of the application and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the AD5555CRUZ replace the DAC8802IPW in all applications?

A: Substitution is valid when the application supply voltage is fixed at 5V. If the design requires operation across the 2.7V to 5.5V range, the DAC8802IPW is the appropriate choice.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 16-TSSOP package with 0.173" width (4.40mm), ensuring identical PCB footprint and mounting compatibility.

Q: What is the difference in moisture sensitivity?

A: The DAC8802IPW has MSL 2 rating (1-year shelf life), while the AD5555CRUZ has MSL 1 rating (unlimited shelf life). This affects storage and handling requirements but does not impact electrical performance.

Q: Do both parts require the same reference voltage configuration?

A: Yes. Both parts use external reference input, requiring identical external reference circuit design.

Q: Are there differences in settling time or linearity?

A: No. Both parts specify 500ns typical settling time and ±1 LSB maximum INL/DNL, providing equivalent performance in these parameters.
