AD676JD Equivalent & Substitute Parts

Part Overview

The AD676JD is a 16-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc., configured as a single-channel SAR (Successive Approximation Register) architecture device in a 28-CDIP through-hole package. This data acquisition component operates with external voltage references, dual supply rails (±12V analog, 5V digital), and delivers a 100 kHz sampling rate. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified when all critical electrical and mechanical parameters remain identical across the device family, ensuring direct interchangeability in existing circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the AD676JD is determined by strict equivalence across all specified electrical and mechanical parameters. The substitute parts AD676JDZ and AD676KDZ maintain identical specifications in the following critical areas:

• 16-bit resolution and 100 kHz sampling rate
• Single-channel, single-ended input configuration
• SAR architecture with external reference requirement
• Dual supply voltage requirements (±12V analog, 5V digital)
• 28-CDIP through-hole package geometry
• Operating temperature range of 0°C to 70°C
• ROHS3 compliance and MSL Level 1 rating

All three parts share the same base product number (AD676) and are manufactured by Analog Devices Inc. The suffix designations (JD, JDZ, KDZ) indicate packaging variations and temperature grade classifications within the same functional family, but do not alter the core electrical performance or pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AD676JD, AD676JDZ, and AD676KDZ—are active production components from Analog Devices Inc. with identical ROHS3 compliance and MSL Level 1 ratings. Selection between these parts is based on packaging tube availability and inventory status rather than functional or electrical differences. The AD676JD maintains 1706 units in stock, AD676JDZ provides 1233 units, and AD676KDZ offers 1075 units. For applications requiring immediate component availability, the AD676JD is the primary choice. For supply chain continuity or alternative sourcing, AD676JDZ and AD676KDZ provide equivalent functional performance with identical electrical specifications and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can AD676JDZ and AD676KDZ be used as direct replacements for AD676JD in existing PCB designs?

A: Yes. All three parts share identical pin configurations, electrical specifications, and 28-CDIP package dimensions. No circuit modifications or PCB layout changes are required for substitution.

Q: What is the difference between the AD676JD, AD676JDZ, and AD676KDZ part numbers?

A: The suffix designations indicate packaging format and temperature grade classifications within the AD676 family. The JD suffix denotes tube packaging with standard temperature range (0°C to 70°C), while JDZ and KDZ represent alternative packaging or grading options. All maintain identical functional performance and electrical parameters.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts carry ROHS3 compliance, REACH unaffected status, and MSL Level 1 moisture sensitivity rating. Regulatory and environmental compliance is equivalent across all variants.

Q: What supply voltage requirements must be met for any of these ADC parts?

A: All three parts require dual supply rails: ±12V for analog circuitry and 5V for digital logic. External voltage reference circuits must be provided; these devices do not include internal reference sources.

Q: Is the 28-CDIP through-hole package identical across all three part numbers?

A: Yes. All parts use the 28-CDIP package with 0.600-inch (15.24mm) body width. Through-hole mounting specifications and PCB footprint requirements are identical.
