AD670JP Equivalent & Substitute Parts
Part Overview
The AD670JP is an 8-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc., designed for data acquisition applications requiring 2-input differential conversion with SAR (Successive Approximation Register) architecture. The device operates with 5V analog and digital supply voltages and features true bipolar input capability in a 20-PLCC surface mount package.
The AD670JP is classified as obsolete. Identifying equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Substitute Part Grouping Explanation
Substitution eligibility for the AD670JP is determined by strict equivalence across the following critical parameters:
- Resolution & Architecture: 8-bit SAR ADC configuration
- Input Configuration: 2 differential inputs
- Data Interface: Parallel output
- Supply Voltages: 5V analog and digital supplies
- Input Characteristics: True bipolar capability
- Package Compatibility: 20-PLCC (9x9) surface mount form factor
- Operating Temperature: 0°C ~ 70°C range
- Reference Type: Internal reference
The AD670JPZ qualifies as a direct substitute based on identical electrical specifications, package dimensions, and pinout compatibility. The variant designation (JPZ vs. JP) reflects manufacturing process or packaging material updates while maintaining full functional equivalence.

Engineering Selection Recommendations
The AD670JPZ is a direct functional equivalent to the AD670JP. Both devices share identical electrical characteristics, pinout, and package specifications, enabling drop-in replacement in existing designs.
The AD670JPZ provides additional compliance documentation: ROHS3 compliance and REACH unaffected status. These certifications may be required for new procurement or system updates subject to environmental regulations.
Both parts are classified as obsolete. Component selection should prioritize availability verification through authorized distributors. The AD670JPZ currently maintains higher inventory levels (959 units) compared to the AD670JP (1445 units), though both are subject to discontinuation.
Frequently Asked Questions (FAQ)
Q: Can AD670JPZ replace AD670JP in existing circuit designs?
A: Yes. The AD670JPZ is a direct substitute with identical electrical specifications, pinout, and 20-PLCC package dimensions. No circuit modifications are required.
Q: What is the difference between AD670JP and AD670JPZ?
A: The variant designation reflects manufacturing process or packaging material updates. Electrical performance and functional specifications remain identical. The AD670JPZ includes documented ROHS3 compliance and REACH status.
Q: Are there any package compatibility concerns?
A: No. Both parts use the 20-PLCC (9x9) surface mount package with identical J-lead configuration and pinout. PCB footprints and assembly processes are interchangeable.
Q: What compliance certifications apply to these parts?
A: Both parts carry EAR99 export classification and HTSUS code 8542.39.0001. The AD670JPZ additionally documents ROHS3 compliance and REACH unaffected status. The AD670JP compliance status is not specified in available documentation.
Q: Are these parts still in production?
A: No. Both the AD670JP and AD670JPZ are classified as obsolete. Procurement should be limited to available inventory from authorized distributors.
Q: What is the operating temperature range for these devices?
A: Both parts operate across 0°C to 70°C. Applications requiring extended temperature ranges require alternative device selection.
