Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD8804ARZ are determined by strict equivalence across the following critical parameters:

• Number of bits: 8
• Number of D/A converters: 12
• Output type: Voltage - Unbuffered
• Data interface: SPI
• Architecture: R-2R
• Settling time: 600ns (Typ)
• INL/DNL specifications: ±0.5, ±0.25 (LSB)
• Supply voltage ranges: 2.7V ~ 5.5V (both analog and digital)
• Package type: 20-SOIC
• Operating temperature range: -40°C ~ 85°C

The AD8802ARZ meets all these criteria and is classified as a parametric equivalent. Both devices share identical functional specifications, electrical performance characteristics, and physical packaging, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the AD8804ARZ and AD8802ARZ are active products from Analog Devices Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on:

• Inventory availability and lead times from component suppliers
• Cost considerations across procurement cycles
• Supply chain logistics and regional distribution
• Product lifecycle status, both currently active

Both devices maintain ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements for industrial and commercial applications. The identical MSL rating of 1 (Unlimited) indicates equivalent moisture handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can AD8802ARZ replace AD8804ARZ in existing designs?

A: Yes. The AD8802ARZ is a parametric equivalent with identical specifications across all critical parameters: 8-bit resolution, 12 D/A converters, SPI interface, R-2R architecture, settling time, supply voltage ranges, accuracy specifications, operating temperature range, and 20-SOIC package. No circuit modifications are required.

Q: Are there any package or pinout differences?

A: No. Both devices use the 20-SOIC package with identical dimensions (0.295" × 7.50mm width). Pinout and mounting type are identical, enabling direct PCB substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AD8804ARZ and AD8802ARZ are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). They meet equivalent environmental and regulatory requirements.

Q: What is the difference between these two part numbers?

A: Based on provided specifications, no functional or electrical differences exist between AD8804ARZ and AD8802ARZ. Both are TrimDAC® series devices with identical performance characteristics. Differences, if any, are not reflected in the provided technical parameters.

Q: Can I use either part for new designs?

A: Yes. Both parts are active products suitable for new designs. Selection should be based on supplier availability, lead time, and cost at the time of procurement.
