AD8802ARUZ Equivalent & Substitute Parts

Part Overview

The AD8802ARUZ is an 8-bit digital-to-analog converter (DAC) from Analog Devices Inc., part of the TrimDAC® series. This integrated circuit features 12 D/A converters in a 20-TSSOP surface mount package and is designed for data acquisition applications requiring voltage output conversion. The device operates across a wide supply voltage range (2.7V to 5.5V for both analog and digital supplies) and maintains active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package and functional architecture.

Key Parameters

Substitute Part Grouping Explanation

The AD8804ARUZ qualifies as a parametric equivalent to the AD8802ARUZ based on strict alignment of the following critical parameters:

• Resolution and Converter Count: Both devices feature 8-bit resolution with 12 D/A converters
• Electrical Performance: Identical settling time (600ns typical), INL/DNL specifications (±0.5, ±0.25 LSB), and R-2R architecture
• Supply Voltage Compatibility: Both operate across 2.7V to 5.5V for analog and digital supplies
• Interface and Reference: Both use SPI data interface with external reference type
• Package and Mounting: Identical 20-TSSOP package (0.173", 4.40mm width) with surface mount capability
• Compliance and Status: Both maintain ROHS3 compliance, MSL Level 1, and active product status

Substitution is valid when these parameters remain constant across the application circuit design.

Parameter Comparison

Engineering Selection Recommendations

Both the AD8802ARUZ and AD8804ARUZ maintain active product status with full ROHS3 compliance and MSL Level 1 rating, indicating unlimited moisture sensitivity protection. Selection between these parts should be based on inventory availability and supply chain considerations, as electrical and mechanical specifications are identical. Both devices are suitable for applications requiring 8-bit DAC functionality in data acquisition systems operating within the specified temperature and supply voltage ranges. Compliance certifications (REACH Unaffected, ECCN EAR99) are equivalent across both parts.
