AD676KN Equivalent & Substitute Parts

Part Overview

The AD676KN is a 16-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc., designed for single-ended input data acquisition applications. It features a Successive Approximation Register (SAR) architecture with a 100 kHz sampling rate and operates with ±12V analog supply and 5V digital supply. The device is packaged in a 28-pin DIP configuration for through-hole mounting.

The AD676KN is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for systems utilizing this ADC.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD676KN are determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters define substitutability:

• Resolution: 16 Bit
• Sampling Rate: 100 kHz
• Number of Inputs: 1
• Input Type: Single Ended
• Architecture: SAR
• Data Interface: Parallel
• Reference Type: External
• Voltage - Supply, Analog: ±12V
• Voltage - Supply, Digital: 5V
• Operating Temperature Range: 0°C to 70°C
• Package / Case: 28-DIP (0.600", 15.24mm)
• Mounting Type: Through Hole

Parts meeting all these criteria are classified as direct substitutes. The AD676JNZ and AD676KNZ both satisfy these requirements and are therefore equivalent to the AD676KN.

Parameter Comparison

Engineering Selection Recommendations

Both AD676JNZ and AD676KNZ are direct electrical and mechanical equivalents to the AD676KN. Selection between these substitutes should be based on the following factors:

Product Status: The AD676KN is obsolete. Both AD676JNZ and AD676KNZ are active products, ensuring long-term availability and supply chain continuity.

Compliance Certifications: Both substitute parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. The AD676KN compliance status is not specified.

Packaging: AD676KNZ is supplied in Tube packaging, while AD676JNZ packaging is not specified. Consider packaging requirements for your assembly and handling processes.

Inventory Availability: AD676JNZ has 1,852 units in stock, and AD676KNZ has 971 units in stock, both providing adequate supply for component procurement.

For new designs or production requiring component replacement, either AD676JNZ or AD676KNZ is suitable. For applications with specific packaging or compliance requirements, verify the exact packaging specification of AD676JNZ before final selection.

Frequently Asked Questions (FAQ)

Q: Can AD676JNZ and AD676KNZ be used interchangeably with AD676KN?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical specifications for resolution, sampling rate, input configuration, supply voltages, operating temperature range, and package type (28-DIP through-hole).

Q: Why is the AD676KN listed as obsolete?

A: The AD676KN has reached end-of-life status. AD676JNZ and AD676KNZ are active alternatives that maintain full functional equivalence while ensuring ongoing availability.

Q: Are there any differences in pin configuration between these parts?

A: No. All three parts use the same 28-DIP package with identical pin assignments and electrical characteristics.

Q: Do the substitute parts meet current environmental standards?

A: Yes. Both AD676JNZ and AD676KNZ are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations. The AD676KN compliance status is not specified.

Q: What is the difference between AD676JNZ and AD676KNZ?

A: Both parts are electrically identical. The primary difference is packaging: AD676KNZ is supplied in Tube packaging. Packaging specifications for AD676JNZ are not provided. Select based on your assembly and handling requirements.

Q: Can I use these parts in existing designs without circuit modifications?

A: Yes. The electrical and mechanical equivalence of these parts ensures direct substitution without circuit redesign or PCB modifications.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
