AD9762ARRL Equivalent & Substitute Parts

Part Overview

The AD9762ARRL is a 12-bit Digital to Analog Converter (DAC) manufactured by Analog Devices Inc., designed for data acquisition applications requiring current-output unbuffered conversion. The device features parallel data interface, external and internal reference capability, and operates across a 2.7V to 5.5V supply range. The AD9762ARRL is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD9762ARRL is determined by strict equivalence across the following critical parameters:

• 12-bit resolution with single D/A converter
• Current-output unbuffered architecture with differential output capability
• Parallel data interface supporting external and internal reference modes
• Supply voltage range: 2.7V to 5.5V (both analog and digital)
• 28-SOIC surface mount package
• Operating temperature range: -40°C to 85°C

Substitute parts must maintain identical or superior electrical performance within these constraints. Settling time and INL/DNL specifications are evaluated for functional compatibility. Parts meeting these criteria are classified as direct or similar substitutes based on product status and availability.

Parameter Comparison

Engineering Selection Recommendations

AD9762ARZRL (Analog Devices Inc.) is the primary direct substitute for the AD9762ARRL. Both parts share identical electrical specifications, 28-SOIC packaging, and current-source architecture. The AD9762ARZRL is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating, providing superior long-term availability and supply chain stability compared to the obsolete AD9762ARRL.

DAC902U and DAC902U/1K (Texas Instruments SpeedPlus™ series) are functionally equivalent alternatives meeting all core substitution criteria. These parts deliver improved settling time performance (30ns versus 35ns) and superior INL/DNL specifications (±1, ±0.5 LSB). Both maintain active product status and ROHS3 compliance. The DAC902U/1K variant offers higher inventory availability (3300 pcs). Moisture sensitivity is rated MSL 2 (1 Year), requiring appropriate handling protocols during storage and assembly.

THS5661AIDW (Texas Instruments CommsDAC™ series) meets all functional substitution requirements with superior INL/DNL performance (±0.75, ±0.5 LSB). The minimum supply voltage is 3V (versus 2.7V for other options), which may restrict use in applications requiring lower voltage operation. This part maintains active status, ROHS3 compliance, and unlimited moisture sensitivity (MSL 1).

Selection should prioritize AD9762ARZRL for direct replacement in existing designs. Texas Instruments alternatives are suitable for new designs where supply voltage constraints do not apply and improved performance margins are beneficial.

Frequently Asked Questions (FAQ)

Q: Can AD9762ARZRL directly replace AD9762ARRL without circuit modification?

A: Yes. The AD9762ARZRL is a direct substitute with identical electrical specifications, pinout, and 28-SOIC package. No circuit modifications are required. The primary difference is product status (active versus obsolete) and compliance certifications.

Q: What are the key differences between Analog Devices and Texas Instruments DAC options?

A: All substitute parts maintain identical 12-bit resolution, parallel interface, and 28-SOIC packaging. Texas Instruments DAC902U and DAC902U/1K offer faster settling time (30ns) and tighter INL/DNL tolerance (±0.5 LSB DNL). Analog Devices AD9762ARZRL and THS5661AIDW maintain 35ns settling time. Supply voltage minimums differ: Analog Devices parts support 2.7V; THS5661AIDW requires 3V minimum.

Q: Are there moisture sensitivity considerations for substitute selection?

A: Yes. AD9762ARZRL and THS5661AIDW carry MSL 1 (unlimited moisture sensitivity), suitable for standard storage and assembly environments. DAC902U and DAC902U/1K carry MSL 2 (1 Year), requiring controlled humidity storage and accelerated assembly timelines after package opening.

Q: Which substitute offers the best performance specifications?

A: THS5661AIDW provides superior INL/DNL performance (±0.75, ±0.5 LSB). DAC902U and DAC902U/1K offer the fastest settling time (30ns). Selection depends on application-specific performance requirements and supply voltage constraints.

Q: Is the 28-SOIC package identical across all substitute parts?

A: Yes. All parts use 28-SOIC (0.295", 7.50mm Width) surface mount packaging with identical pinout and footprint compatibility. PCB layout and assembly processes require no modification.
