AD7880BR Equivalent & Substitute Parts

Part Overview

The AD7880BR is a 12-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc., designed for data acquisition applications requiring dual-channel single-ended input conversion. The device features a Successive Approximation Register (SAR) architecture with a 66 kSPS sampling rate and operates from 5V supply rails. The AD7880BR is currently classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support, design updates, and procurement continuity.

Substitute Part Grouping Explanation

Substitute parts for the AD7880BR are identified based on strict electrical and mechanical parameter matching within the AD7880 product family. The substitution logic is based on the following criteria:

Primary Substitution Criteria:

• Resolution: 12 bits
• Sampling Rate: 66 kSPS
• Input Channels: 2 (single-ended)
• Data Interface: Parallel
• Architecture: SAR
• Supply Voltages: 5V analog and digital
• Operating Temperature: -40°C to +85°C
• Package: 24-SOIC form factor
• Mounting: Surface Mount

All identified substitutes maintain identical electrical specifications and mechanical compatibility. Differences exist only in product status, packaging format, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

AD7880BRZ is the primary direct substitute for the AD7880BR. Both parts share identical electrical and mechanical specifications. The AD7880BRZ carries Active product status, ensuring continued manufacturer support and availability. This part is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for new designs and procurement.

AD7880CRZ is a parametric equivalent offering identical functional and electrical performance. The AD7880CRZ is supplied in Tube packaging and maintains Active product status. Like the AD7880BRZ, it is ROHS3 Compliant and REACH Unaffected. Selection between AD7880BRZ and AD7880CRZ should be based on packaging requirements and inventory availability.

For applications currently using the obsolete AD7880BR, migration to either AD7880BRZ or AD7880CRZ is electrically and mechanically transparent, requiring no circuit modifications or design changes.

Frequently Asked Questions (FAQ)

Q: Can AD7880BRZ and AD7880CRZ be used interchangeably with AD7880BR?

A: Yes. All three parts are electrically and mechanically identical. They share the same 12-bit resolution, 66 kSPS sampling rate, dual single-ended input channels, 5V supply requirements, and 24-SOIC package. Pin-for-pin compatibility is maintained across all three variants.

Q: What is the difference between AD7880BRZ and AD7880CRZ?

A: The primary difference is packaging format. AD7880CRZ is supplied in Tube packaging, while AD7880BRZ packaging format is not specified in the provided data. Both parts are electrically identical and carry Active product status with ROHS3 Compliance and REACH Unaffected certifications.

Q: Why is the AD7880BR classified as obsolete?

A: The AD7880BR has reached end-of-life status. Active substitutes (AD7880BRZ and AD7880CRZ) are available from Analog Devices Inc. and should be used for new designs and ongoing procurement.

Q: Are there any circuit modifications required when replacing AD7880BR with AD7880BRZ or AD7880CRZ?

A: No circuit modifications are required. The substitute parts maintain identical pin assignments, electrical characteristics, and functional specifications. Direct replacement is possible without design changes.

Q: What are the compliance certifications for the substitute parts?

A: Both AD7880BRZ and AD7880CRZ are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What is the MSL rating for these parts?

A: All three parts carry MSL 3 (168 Hours) moisture sensitivity level rating, indicating standard moisture handling requirements for surface mount assembly.
