AD677JD Equivalent & Substitute Parts

Part Overview

The AD677JD is a 16-bit Analog to Digital Converter manufactured by Analog Devices Inc., designed for single-ended input data acquisition applications. This SAR (Successive Approximation Register) architecture device operates with external voltage references and dual supply voltages (±12V analog, 5V digital). The AD677JD is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications requiring reliable analog-to-digital conversion at 100 kHz sampling rates.

Equivalent and substitute parts are identified when components share identical electrical specifications, compatible package configurations, and equivalent functional performance within the same product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD677JD is determined by strict equivalence across the following critical parameters:

• 16-bit resolution and 100 kHz sampling rate
• Single-ended input configuration with one analog input channel
• SAR architecture with external reference requirement
• Dual supply voltage specifications (±12V analog, 5V digital)
• Serial data interface and S/H-ADC configuration with 1:1 ratio
• Through-hole mounting technology
• Operating temperature range of 0°C to 70°C
• Active product status with ROHS3 compliance

The AD677JNZ qualifies as a direct substitute based on identical electrical performance and functional specifications. The primary distinction between these components is the package configuration and supplier device packaging designation.

Parameter Comparison

Engineering Selection Recommendations

Both the AD677JD and AD677JNZ are active products from Analog Devices Inc. with full ROHS3 compliance and identical electrical specifications. Selection between these components should be based on:

• Package configuration requirements: AD677JD uses 16-CDIP packaging while AD677JNZ uses 16-DIP packaging. Both maintain the same 0.300" (7.62mm) pitch and through-hole mounting compatibility.
• Supplier device packaging: AD677JD is supplied in standard packaging, while AD677JNZ is supplied in tube packaging.
• Inventory availability and lead time considerations.
• PCB layout and footprint compatibility with existing designs.

Both components maintain identical electrical performance, supply voltage requirements, sampling characteristics, and temperature operating ranges. Component selection should prioritize design compatibility with existing PCB layouts and packaging availability.

Frequently Asked Questions (FAQ)

Q: Can AD677JNZ replace AD677JD in existing designs?

A: Yes. Both components share identical electrical specifications, including 16-bit resolution, 100 kHz sampling rate, external reference requirement, and dual supply voltages (±12V analog, 5V digital). The primary consideration is package compatibility. Both use through-hole mounting with 0.300" pitch, making them mechanically compatible on standard PCB layouts.

Q: What is the difference between 16-CDIP and 16-DIP packaging?

A: Both designations refer to 16-pin dual inline packages with 0.300" (7.62mm) pitch suitable for through-hole mounting. The packaging difference does not affect electrical performance or functional compatibility. PCB footprints designed for either package type will accommodate both components.

Q: Are both parts suitable for industrial temperature applications?

A: Both AD677JD and AD677JNZ operate within the 0°C to 70°C temperature range. For applications requiring extended temperature performance, alternative product lines from Analog Devices Inc. should be evaluated.

Q: Do both parts require the same external reference circuit?

A: Yes. Both components use external voltage references and require identical reference circuit design. Supply voltage requirements (±12V analog, 5V digital) are identical across both parts.

Q: What is the significance of the tube packaging for AD677JNZ?

A: Tube packaging affects component handling, storage, and automated assembly processes. Functionally and electrically, tube-packaged AD677JNZ components are identical to standard-packaged AD677JD components. Packaging selection should align with manufacturing and assembly requirements.
