Substitute Part Grouping Explanation
Substitution of the LMV358AM8X is determined by the following critical parameters:
Package Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure direct PCB footprint compatibility.
Electrical Specifications: Substitute parts must maintain compatibility across the following ranges:
- Supply voltage span: 2.7 V minimum to 5.5 V maximum
- Operating temperature: -40°C to 125°C
- Output type: Rail-to-rail configuration
- Number of circuits: 2 (dual-channel)
- Mounting type: Surface mount
Amplifier Type Consideration: The LMV358AM8X is classified as a general purpose amplifier. Substitutes may include general purpose, voltage feedback, or CMOS amplifier types, provided all electrical parameters remain within compatible ranges.
Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level to ensure regulatory and manufacturing process compatibility.
Substitutes are grouped into three categories based on product status and electrical characteristics: active onsemi alternatives, active Analog Devices alternatives, and active third-party manufacturer alternatives.

Engineering Selection Recommendations
onsemi Active Alternatives:
LMV358DR2G is an active onsemi product with identical supply voltage range (2.7 V to 5.5 V) and 8-SOIC package. This part operates at reduced temperature range (-40°C to 85°C) compared to the LMV358AM8X. The LMV358DR2G provides higher output current capability (160 mA per channel versus 34 mA), making it suitable for applications requiring increased drive capability.
LMV932DR2G is an active CMOS alternative with extended lower supply voltage capability (1.8 V minimum) and identical upper temperature rating (-40°C to 125°C). This part features lower supply current consumption (75 µA versus 100 µA) and maintains the 8-SOIC package. The LMV932DR2G operates at reduced slew rate (0.35 V/µs) and lower output current per channel (80 mA).
NCS20082DR2G and NCV20082DR2G are active general purpose amplifiers with identical package and temperature range. Both parts feature lower supply current (48 µA), extended lower supply voltage (1.8 V minimum), and improved input offset voltage (500 µV). Output current per channel is reduced to 15 mA.

Frequently Asked Questions (FAQ)
Q: Can LMV358DR2G directly replace LMV358AM8X in all applications?
A: LMV358DR2G shares the same 8-SOIC package and supply voltage range (2.7 V to 5.5 V). However, the operating temperature range is reduced from -40°C to 125°C to -40°C to 85°C. Direct replacement is valid only for applications operating within the -40°C to 85°C range. LMV358DR2G provides higher output current (160 mA per channel versus 34 mA), which may affect circuit behavior in current-limited designs.
Q: What is the primary difference between LMV932DR2G and LMV358AM8X?
A: LMV932DR2G is a CMOS amplifier type versus the general purpose type of LMV358AM8X. Both maintain the 8-SOIC package and -40°C to 125°C operating range. LMV932DR2G offers lower supply current (75 µA versus 100 µA) and extended lower supply voltage capability (1.8 V minimum). The trade-off is reduced slew rate (0.35 V/µs versus 1.5 V/µs) and lower output current per channel (80 mA versus 34 mA).
Q: Are NCS20082DR2G and NCV20082DR2G interchangeable?
A: NCS20082DR2G and NCV20082DR2G have identical electrical specifications, package type (8-SOIC), and operating parameters. Both are active onsemi products with general purpose amplifier classification. The parts are functionally equivalent for substitution purposes.
Q: Why does AD8062ARZ have significantly higher slew rate and bandwidth than LMV358AM8X?
A: AD8062ARZ is classified as a voltage feedback amplifier optimized for high-speed applications, with slew rate of 650 V/µs and gain bandwidth product of 320 MHz. LMV358AM8X is a general purpose amplifier with slew rate of 1.5 V/µs and gain bandwidth product of 1.4 MHz. AD8062ARZ is suitable only for applications requiring high-speed performance. The higher supply current (6.8 mA per channel pair) reflects the increased performance capability.
Q: Can LMV358IDR replace LMV358AM8X?
A: LMV358IDR has a different package type (14-SOIC versus 8-SOIC), which prevents direct PCB footprint compatibility. Additionally, the operating temperature range is reduced to -25°C to 85°C. LMV358IDR is not a direct substitute without PCB layout modification.
Q: Which substitute part best matches the original LMV358AM8X specifications?
A: AD8542ARZ and AD8542ARZ-REEL provide the closest match to LMV358AM8X. Both are general purpose amplifiers with identical supply voltage range (2.7 V to 5.5 V), full operating temperature range (-40°C to 125°C), 8-SOIC package, and comparable gain bandwidth product (1 MHz). These parts are active products with established manufacturing support.
Q: What is the significance of MSL 1 (Unlimited) rating for all listed parts?
A: MSL 1 (Unlimited) moisture sensitivity level indicates that these components have no moisture sensitivity restrictions. Parts can be stored and handled without special moisture control measures, simplifying inventory management and manufacturing processes compared to higher MSL ratings.
Q: Are all substitute parts ROHS3 compliant?
A: All substitute parts listed in this reference maintain ROHS3 compliance, ensuring compatibility with regulatory requirements and manufacturing standards equivalent to the original LMV358AM8X.
