AD767KN Equivalent & Substitute Parts

Part Overview

The AD767KN is a 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc., designed for data acquisition applications requiring voltage output conversion. This component features a single DAC channel with buffered voltage output, parallel data interface, and support for both external and internal reference configurations. The AD767KN is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the AD767KN is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion capability
• Channel Configuration: Single DAC channel
• Output Configuration: Voltage output with buffering
• Interface Type: Parallel data interface
• Reference Configuration: Support for external and internal references
• Settling Time: 3µs maximum
• Linearity Specifications: INL/DNL of ±0.25 LSB
• Package Type: 24-DIP form factor
• Supply Voltage Range: ±11.4V ~ 16.5V analog supply
• Operating Temperature Range: 0°C ~ 70°C

The AD767KNZ qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status and packaging configuration.

Engineering Selection Recommendations

The AD767KNZ is the direct functional equivalent of the AD767KN. Selection between these components should be based on the following factors:

Product Status Consideration: The AD767KN is classified as obsolete, while the AD767KNZ maintains active product status. For new designs and long-term system support, the AD767KNZ is the appropriate selection.

Compliance and Certification: The AD767KNZ carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for applications subject to environmental and hazardous substance restrictions. The AD767KN does not specify these certifications.

Packaging and Supply Chain: The AD767KNZ is supplied in tube packaging, whereas the AD767KN packaging configuration is not specified. Tube packaging facilitates automated assembly processes and provides standardized handling for production environments.

Electrical and Mechanical Equivalence: Both components are electrically and mechanically identical across all specified parameters, including resolution, settling time, linearity, supply voltage requirements, operating temperature range, and 24-DIP package form factor.

Frequently Asked Questions (FAQ)

Q: Can the AD767KNZ directly replace the AD767KN in existing designs?

A: Yes. The AD767KNZ is electrically and mechanically equivalent to the AD767KN across all specified parameters. Both components feature identical 12-bit resolution, 3µs settling time, ±0.25 LSB linearity specifications, parallel data interface, and 24-DIP package configuration. Pin-for-pin compatibility is maintained.

Q: What is the primary reason to transition from AD767KN to AD767KNZ?

A: The AD767KN is classified as obsolete, while the AD767KNZ maintains active product status. This distinction ensures continued availability, manufacturing support, and compliance with current regulatory standards. The AD767KNZ also carries ROHS3 compliance and REACH unaffected certification.

Q: Are there any differences in electrical performance between these components?

A: No. Both components are specified identically for all electrical parameters, including supply voltage range (±11.4V ~ 16.5V), operating temperature (0°C ~ 70°C), settling time (3µs), and linearity (INL/DNL ±0.25 LSB).

Q: What packaging differences exist between AD767KN and AD767KNZ?

A: The AD767KNZ is supplied in tube packaging, which is standard for production environments and automated assembly. The AD767KN packaging configuration is not specified in available documentation.

Q: Are both components suitable for new product designs?

A: The AD767KNZ is the appropriate selection for new designs due to its active product status and regulatory compliance certifications. The AD767KN, being obsolete, should be reserved for legacy system maintenance only.

Q: Do these components require different PCB layouts or design considerations?

A: No. Both components use the 24-DIP (0.300", 7.62mm) package with through-hole mounting. PCB layouts, footprints, and design considerations are identical.
