Substitute Part Grouping Explanation

Substitution of the AD7808BR is determined by strict equivalence across the following critical parameters:

• Resolution & Channel Count: 10-bit resolution with 8 independent DAC channels
• Output Characteristics: Voltage-buffered output configuration
• Interface Protocol: SPI serial data interface
• Supply Voltage Range: 3V to 5.5V for both analog and digital supplies
• Settling Time: 4µs maximum settling time
• Linearity Specifications: INL/DNL performance of ±4 LSB (Max) and ±0.125 LSB
• Package Compatibility: 24-SOIC surface mount package with identical physical dimensions
• Temperature Range: -40°C to 85°C operating specification

The AD7808BRZ qualifies as a direct substitute based on complete alignment with all electrical parameters and package specifications. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The AD7808BRZ is the direct equivalent substitute for the AD7808BR. Both components share identical electrical specifications, performance characteristics, and physical packaging. The AD7808BRZ holds active product status, ensuring continued availability and manufacturer support. The AD7808BRZ carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for new designs and procurement cycles. Selection of the AD7808BRZ eliminates obsolescence risk while maintaining complete functional and mechanical compatibility with existing AD7808BR implementations.

Frequently Asked Questions (FAQ)

Q: Can the AD7808BRZ directly replace the AD7808BR in existing designs?

A: Yes. The AD7808BRZ is electrically and mechanically identical to the AD7808BR. All electrical parameters, including resolution, settling time, supply voltage ranges, and output characteristics are equivalent. The 24-SOIC package dimensions and pinout are identical, enabling direct PCB substitution.

Q: What is the primary difference between AD7808BR and AD7808BRZ?

A: The AD7808BR is classified as obsolete, while the AD7808BRZ maintains active product status. The AD7808BRZ includes ROHS3 compliance and REACH unaffected certifications. Packaging format differs: AD7808BR uses standard packaging while AD7808BRZ is supplied in tube format.

Q: Are there any compatibility concerns when switching from AD7808BR to AD7808BRZ?

A: No compatibility concerns exist. Both parts operate identically across all specified electrical parameters and environmental conditions. The 24-SOIC package, pinout, and functional interface are unchanged.

Q: Does the AD7808BRZ meet current regulatory requirements?

A: Yes. The AD7808BRZ is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for component procurement and deployment.

Q: What is the significance of the MSL rating for these components?

A: Both the AD7808BR and AD7808BRZ carry MSL 3 rating with a 168-hour floor life. This moisture sensitivity level requires controlled storage conditions and handling procedures during assembly to prevent moisture-induced failures.
