AD7980ARMZRL7 Equivalent & Substitute Parts

Part Overview

The AD7980ARMZRL7 is a 16-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc., part of the PulSAR® series. This SAR (Successive Approximation Register) architecture device features a single pseudo-differential input with a 1 MSPS sampling rate and external reference configuration. The device operates on 2.375V to 2.625V supply voltage for both analog and digital domains, housed in a 10-MSOP surface mount package.

The AD7980ARMZRL7 maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Finding equivalent or substitute parts becomes necessary when addressing supply chain constraints, inventory availability, or design flexibility requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD7980ARMZRL7 is determined by strict equivalence across the following critical parameters:

• 16-bit resolution and 1 MSPS sampling rate
• Single pseudo-differential input configuration
• SAR architecture with external reference
• SPI and DSP data interface support
• Identical supply voltage range (2.375V ~ 2.625V) for both analog and digital domains
• 10-MSOP surface mount package with 0.118" (3.00mm) width
• Operating temperature range of -40°C to 125°C
• Active product status with ROHS3 compliance and MSL 1 rating

The AD7980BRMZRL7 qualifies as a parametric equivalent substitute, meeting all specified electrical and mechanical requirements without deviation.

Parameter Comparison

Engineering Selection Recommendations

Both the AD7980ARMZRL7 and AD7980BRMZRL7 maintain Active product status within the Analog Devices PulSAR® ADC portfolio. Selection between these parts should be based on inventory availability and supply chain considerations, as both devices carry identical ROHS3 compliance and REACH unaffected status.

The AD7980ARMZRL7 currently maintains higher inventory levels (20,200 units) compared to the AD7980BRMZRL7 (2,744 units). For applications requiring immediate availability, the primary part number is preferred. For long-term supply chain flexibility, either part provides equivalent functional and mechanical compatibility.

Both devices are suitable for applications requiring 16-bit precision data acquisition with external reference configuration in compact 10-MSOP surface mount packages across industrial temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the AD7980BRMZRL7 be used as a direct replacement for the AD7980ARMZRL7?

A: Yes. The AD7980BRMZRL7 is a parametric equivalent with identical electrical specifications, pin configuration, and package dimensions. No circuit modifications are required for substitution.

Q: Are there differences in performance characteristics between these parts?

A: No. Both devices share identical resolution (16-bit), sampling rate (1 MSPS), input configuration (single pseudo-differential), and supply voltage requirements (2.375V ~ 2.625V). Performance characteristics are equivalent.

Q: Do both parts support the same data interfaces?

A: Yes. Both the AD7980ARMZRL7 and AD7980BRMZRL7 support SPI and DSP data interfaces with identical protocol implementation.

Q: Are there packaging or mounting differences?

A: No. Both parts use the 10-MSOP surface mount package with 0.118" (3.00mm) width. PCB footprints and assembly processes are identical.

Q: What is the significance of the different part number suffixes (A vs. B)?

A: The suffix indicates different manufacturing batches or revisions within the same product line. Both maintain Active status and identical specifications.

Q: Are compliance certifications identical?

A: Yes. Both parts carry ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supplier lead times, as both provide equivalent long-term reliability and performance.
