Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISL5929INZ is determined by the following critical parameters:

• Resolution: 14-bit conversion capability
• Converter Count: Dual D/A converters (2 channels)
• Output Architecture: Current-unbuffered topology with differential output capability
• Data Interface: Parallel input interface
• Reference Configuration: Support for both external and internal reference sources
• Package Form Factor: 48-LQFP (7x7) surface mount package
• Operating Temperature Range: -40°C to 85°C
• Supply Voltage Compatibility: Analog and digital supply ranges must accommodate system requirements

The AD9767ASTZ meets all core functional and package requirements, making it a valid substitute candidate. Both devices share identical resolution, converter count, output type, differential capability, data interface, reference flexibility, package geometry, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

The AD9767ASTZ is a functionally equivalent substitute for the ISL5929INZ based on matching core specifications: 14-bit resolution, dual converter architecture, current-unbuffered differential output, parallel data interface, and identical 48-LQFP package geometry.

Key considerations for substitution:

Supply Voltage Range: The AD9767ASTZ supports a wider analog supply range (3V ~ 5.5V) compared to the ISL5929INZ (2.7V ~ 3.6V). Systems operating at the lower end of the ISL5929INZ range (2.7V ~ 3V) must verify compatibility with the AD9767ASTZ minimum specification of 3V for analog supply.

Linearity Performance: The AD9767ASTZ demonstrates superior INL/DNL specifications (±1.5/±1.0 LSB) relative to the ISL5929INZ (±2.5/±1.5 LSB), indicating tighter accuracy tolerances.

Product Status and Availability: The AD9767ASTZ maintains active production status with documented inventory availability, whereas the ISL5929INZ is obsolete. This substitution ensures long-term component sourcing and supply chain continuity.

Compliance: Both devices are ROHS3 compliant and carry identical ECCN and HTSUS classifications, supporting regulatory and trade requirement alignment.

Frequently Asked Questions (FAQ)

Q: Can the AD9767ASTZ directly replace the ISL5929INZ without circuit modifications?

A: Both devices share identical pin counts, package geometry (48-LQFP 7x7), and functional architecture. Direct PCB-level replacement is feasible. However, verify that your system's analog supply voltage meets the AD9767ASTZ minimum requirement of 3V. If your design operates the ISL5929INZ at 2.7V to 2.99V, circuit modifications to the power supply may be necessary.

Q: What are the key differences between these two 14-bit DACs?

A: The primary differences are manufacturer origin, supply voltage ranges, and linearity specifications. The AD9767ASTZ offers improved INL/DNL performance and operates across a broader supply voltage window. Both devices maintain identical resolution, converter count, output topology, and package form factor.

Q: Is the AD9767ASTZ suitable for applications requiring the ISL5929INZ's 2.7V minimum analog supply?

A: The AD9767ASTZ specifies a 3V minimum for analog supply. Applications strictly limited to 2.7V operation require either voltage regulation to meet the 3V threshold or alternative component selection.

Q: Are there any thermal or reliability differences between these devices?

A: Both devices operate across the identical temperature range (-40°C to 85°C) and carry equivalent moisture sensitivity classifications. Thermal performance data is not provided in the available specifications.

Q: What is the significance of the settling time specification for the AD9767ASTZ?

A: The AD9767ASTZ specifies a typical settling time of 35ns, indicating the time required for the output to stabilize following a digital input change. The ISL5929INZ does not provide this specification. For applications with strict timing requirements, the AD9767ASTZ's documented settling time enables precise system timing calculations.
