AD9764ARU Equivalent & Substitute Parts

Part Overview

The AD9764ARU is a 14-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc., designed for data acquisition applications requiring parallel data interface and current-mode unbuffered output. The device operates across a wide supply voltage range (2.7V to 5.5V) and supports both external and internal reference configurations. The AD9764ARU is classified as obsolete, making identification of equivalent and substitute parts essential for system redesign, production continuation, and long-term component sourcing strategies.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD9764ARU are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters for Substitution:

• Resolution: 14 bits
• Output configuration: Current-mode, unbuffered, differential
• Data interface: Parallel
• Reference capability: External and internal support
• Supply voltage range: 2.7V to 5.5V (both analog and digital)
• Package: 28-TSSOP form factor
• Operating temperature range: -40°C to 85°C

Direct Equivalent: AD9764ARUZ is a direct manufacturer equivalent from Analog Devices Inc., differing only in packaging format (Tube vs. unspecified) and product status (Active vs. Obsolete). All electrical and mechanical specifications are identical.

Functional Substitutes: DAC904E (Burr Brown) and DAC904E/2K5 (Texas Instruments) are functionally compatible alternatives. Both devices maintain the same 14-bit resolution, current-mode unbuffered output, differential configuration, parallel data interface, and 28-TSSOP package. Performance characteristics show minor variations in settling time (30ns vs. 35ns) and INL/DNL specifications (±3, ±2.5 vs. ±2.5, ±1.5), which remain within acceptable tolerance for equivalent operation in most applications.

Parameter Comparison

Engineering Selection Recommendations

AD9764ARUZ (Direct Equivalent): This part is the recommended primary substitute for the AD9764ARU. As an active product from the same manufacturer with identical electrical specifications and 28-TSSOP packaging, it provides seamless compatibility with existing designs. The AD9764ARUZ carries RoHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. Tube packaging is suitable for automated assembly processes.

DAC904E and DAC904E/2K5 (Functional Alternatives): These parts are suitable for applications where the performance differences are acceptable. Both devices offer faster settling time (30ns vs. 35ns) and are currently in active production status. DAC904E/2K5 includes RoHS3 compliance and REACH unaffected certification. The slightly relaxed INL/DNL specifications (±3, ±2.5 LSB) may require system-level validation in precision applications. Both maintain full compatibility with the 28-TSSOP package and parallel data interface requirements.

Compliance Considerations: All substitute parts maintain the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications as the original AD9764ARU, ensuring consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can AD9764ARUZ be used as a direct replacement for AD9764ARU? A: Yes. AD9764ARUZ is electrically and mechanically identical to AD9764ARU. The only differences are packaging format (Tube) and product status (Active). All electrical parameters, pin configurations, and performance specifications are equivalent.

Q: What are the key differences between AD9764ARU and DAC904E? A: Both devices share identical 14-bit resolution, current-mode unbuffered output, differential configuration, parallel data interface, and 28-TSSOP packaging. DAC904E offers improved settling time (30ns vs. 35ns) but has slightly relaxed INL/DNL specifications (±3, ±2.5 LSB vs. ±2.5, ±1.5 LSB). Supply voltage ranges and operating temperature are identical.

Q: Are DAC904E and DAC904E/2K5 interchangeable? A: Both parts are functionally equivalent with identical electrical specifications and 28-TSSOP packaging. DAC904E/2K5 includes RoHS3 compliance and REACH unaffected certification. Selection depends on regulatory requirements and supply chain availability.

Q: Does package format affect circuit compatibility? A: No. All substitute parts use the 28-TSSOP package with identical pin assignments and mechanical dimensions (0.173", 4.40mm Width). Surface mount assembly processes remain unchanged.

Q: What is the impact of different INL/DNL specifications? A: AD9764ARU and AD9764ARUZ specify ±2.5, ±1.5 LSB, while DAC904E and DAC904E/2K5 specify ±3, ±2.5 LSB. The DAC904 variants have slightly higher linearity error. Applications requiring maximum precision should validate performance with the relaxed specifications through system-level testing.

Q: Are all substitute parts suitable for -40°C to 85°C operation? A: Yes. All listed substitute parts maintain the full -40°C to 85°C operating temperature range, ensuring compatibility with industrial and extended-temperature applications.
