Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMV422MM/NOPB is determined by the following critical parameters:

Functional Requirements:

• Dual-channel general-purpose operational amplifier configuration
• Rail-to-rail output capability
• Surface-mount packaging in 10-pin MSOP or TFSOP form factor

Electrical Compatibility:

• Supply voltage range overlap: minimum 2.7 V, maximum 5.5 V
• Input bias current: 5 pA
• Operating temperature range: -40°C to 85°C
• Output drive capability and slew rate characteristics

Regulatory & Compliance:

• ROHS3 compliance
• MSL Level 1 (Unlimited moisture sensitivity)
• REACH unaffected status
• EAR99 export classification

The AD8592ARMZ-REEL qualifies as a manufacturer-recommended substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The LMV422MM/NOPB is classified as obsolete. The AD8592ARMZ-REEL maintains active product status, ensuring continued manufacturer support, availability, and supply chain stability.

Compliance & Certification: Both parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), REACH unaffected status, and EAR99 export classification. No regulatory barriers exist for substitution.

Electrical Performance Differences: The AD8592ARMZ-REEL exhibits higher output current capability (250 mA versus 16 mA per channel) and faster slew rate (5 V/µs versus 3.8 V/µs). These characteristics represent performance enhancements suitable for applications requiring greater drive capability. The lower gain bandwidth product (3 MHz versus 8 MHz) and slightly higher input offset voltage (2 mV versus 1 mV) must be evaluated against specific application requirements.

Supply Voltage Range: The AD8592ARMZ-REEL operates at a minimum supply voltage of 2.5 V (versus 2.7 V for the LMV422MM/NOPB) and maximum of 6 V (versus 5.5 V). This extended range provides additional design flexibility.

Package Compatibility: Both devices are available in identical 10-pin MSOP and 10-TFSOP surface-mount packages with 0.118" (3.00mm) width, enabling direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AD8592ARMZ-REEL be used as a direct replacement for the LMV422MM/NOPB?

A: The AD8592ARMZ-REEL is electrically and mechanically compatible with the LMV422MM/NOPB. Both devices feature dual general-purpose operational amplifiers in identical 10-pin MSOP/TFSOP packages with rail-to-rail output capability. Pin-for-pin compatibility exists. However, the AD8592ARMZ-REEL exhibits different electrical characteristics, including higher output current, faster slew rate, and lower gain bandwidth product. Circuit performance must be validated against application specifications.

Q: What are the key electrical differences between these parts?

A: The AD8592ARMZ-REEL provides 250 mA output current per channel compared to 16 mA for the LMV422MM/NOPB, and a slew rate of 5 V/µs versus 3.8 V/µs. The LMV422MM/NOPB offers higher gain bandwidth product (8 MHz versus 3 MHz) and lower input offset voltage (1 mV versus 2 mV). Supply voltage range differs slightly: AD8592ARMZ-REEL operates from 2.5 V to 6 V, while LMV422MM/NOPB operates from 2.7 V to 5.5 V.

Q: Are there packaging considerations for substitution?

A: Both parts use identical 10-pin MSOP and 10-TFSOP surface-mount packages with 0.118" (3.00mm) width. No PCB layout modifications are required. The AD8592ARMZ-REEL is supplied in Cut Tape (CT) and Digi-Reel® packaging, while the LMV422MM/NOPB packaging format is not specified in available data.

Q: What is the product status difference, and why does it matter?

A: The LMV422MM/NOPB is classified as obsolete, indicating discontinued manufacturing and limited future availability. The AD8592ARMZ-REEL maintains active product status, ensuring ongoing manufacturer support, continued production, and reliable supply chain access for long-term applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the LMV422MM/NOPB and AD8592ARMZ-REEL are ROHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity rating, maintain REACH unaffected status, and are classified as EAR99 for export purposes. No regulatory barriers exist for substitution.

Q: Which part should be selected for new designs?

A: For new designs, the AD8592ARMZ-REEL is the appropriate selection due to its active product status, enhanced output current capability, and extended supply voltage range. The LMV422MM/NOPB should be reserved for legacy system maintenance only.
