AD7568BP Equivalent & Substitute Parts

Part Overview

The AD7568BP is a 12-bit digital-to-analog converter (DAC) with 8 independent output channels, manufactured by Analog Devices Inc. This component features current-unbuffered outputs, external reference capability, and SPI data interface, designed for multi-channel analog signal generation applications. The AD7568BP is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

The AD7568BPZ qualifies as a direct substitute for the AD7568BP based on the following critical parameters:

• Resolution and Channel Count: Both parts maintain 12-bit resolution with 8 independent D/A converters
• Output Configuration: Identical current-unbuffered output type with differential output capability
• Interface and Reference: Both utilize SPI data interface with external reference architecture
• Supply Voltages: Matching 5V analog and digital supply requirements
• Linearity Specifications: Identical INL/DNL performance (±0.5 Max, ±0.9 Max LSB)
• Converter Architecture: Both employ R-2R architecture
• Operating Temperature Range: Identical -40°C to 85°C specification
• Package and Mounting: Both use 44-LCC (J-Lead) surface mount packaging with identical MSL rating

The primary distinction is product status: AD7568BP is obsolete while AD7568BPZ is active, with minor settling time variation (550ns vs 500ns typical).

Parameter Comparison

Engineering Selection Recommendations

The AD7568BPZ is the appropriate substitute for AD7568BP applications. The obsolete status of AD7568BP necessitates transition to the active AD7568BPZ for new procurements and ongoing system support. Both parts maintain electrical and mechanical compatibility across all critical parameters.

The AD7568BPZ carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for current manufacturing standards. The 50ns increase in typical settling time (550ns vs 500ns) remains within acceptable tolerance for most multi-channel DAC applications and does not alter functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can AD7568BPZ directly replace AD7568BP in existing designs? A: Yes. Both parts share identical pin configuration, package type (44-LCC), electrical specifications, and functional characteristics. No circuit modifications are required.

Q: What is the significance of the settling time difference? A: AD7568BPZ has a typical settling time of 550ns compared to AD7568BP's 500ns. This 50ns difference is marginal and does not affect functional compatibility in standard applications. Verify timing requirements against your specific application specifications.

Q: Are there packaging differences between these parts? A: Both use 44-LCC (J-Lead) surface mount packaging with identical MSL rating of 3 (168 Hours). Packaging is fully compatible.

Q: Why is AD7568BP listed as obsolete? A: AD7568BP has reached end-of-life status. AD7568BPZ remains in active production and is the recommended part for all new designs and replacements.

Q: What compliance certifications apply to AD7568BPZ? A: AD7568BPZ is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Are the supply voltage requirements identical? A: Yes. Both parts require 5V for analog supply and 5V for digital supply, with identical operating temperature range of -40°C to 85°C.
