LMV342MM Equivalent & Substitute Parts
Part Overview
The LMV342MM is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, housed in an 8-VSSOP surface mount package. This device features rail-to-rail output capability and operates across a 2.7V to 5.5V supply voltage range, making it suitable for low-power analog signal processing applications. The LMV342MM is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. Substitute parts must maintain functional compatibility through matching electrical characteristics and mechanical packaging standards.

Engineering Selection Recommendations
Primary Recommendation: LMV342MM/NOPB
The LMV342MM/NOPB from National Semiconductor provides direct electrical equivalence to the obsolete LMV342MM. This part maintains identical specifications across all critical parameters: 1V/µs slew rate, 1MHz gain bandwidth product, 0.02pA input bias current, and 700µV input offset voltage. The part is classified as active with substantial inventory availability (128,180 units). However, this part carries RoHS non-compliant status, which may restrict use in applications subject to RoHS3 compliance requirements.
Secondary Recommendation for RoHS3-Compliant Applications: LMV358DMR2G
The LMV358DMR2G from onsemi provides functional substitution with RoHS3 compliance certification. This part maintains the critical 1V/µs slew rate and 1MHz gain bandwidth product. Input bias current increases to 1nA and input offset voltage to 1.7mV, representing acceptable parameter variations for general-purpose applications. Supply current remains comparable at 100µA. Operating temperature range is limited to -40°C to 85°C. This part is actively produced with 34,690 units in stock.
Alternative for Extended Temperature Range: LMV358M8G-13
The LMV358M8G-13 from Diodes Incorporated maintains the -40°C to 125°C operating temperature range of the original LMV342MM while providing RoHS3 compliance.

Frequently Asked Questions (FAQ)
Q1: Can the LMV342MM/NOPB be used as a direct replacement for the obsolete LMV342MM?
A: Yes. The LMV342MM/NOPB provides identical electrical specifications and package compatibility. Both parts feature 1V/µs slew rate, 1MHz gain bandwidth product, 0.02pA input bias current, and 700µV input offset voltage. The primary difference is product status (active vs. obsolete) and packaging format (bulk vs. tape & reel). RoHS compliance status differs; verify compliance requirements for your application.
Q2: What are the key differences between the LMV358DMR2G and the original LMV342MM?
A: The LMV358DMR2G maintains identical slew rate (1V/µs) and gain bandwidth product (1MHz). Input bias current increases from 0.02pA to 1nA, and input offset voltage increases from 700µV to 1.7mV. Supply current decreases slightly from 107µA to 100µA. Operating temperature range is reduced from -40°C to 125°C to -40°C to 85°C. The LMV358DMR2G carries RoHS3 compliance certification, making it suitable for regulated applications.
Q3: Why do the ADA4891-2ARMZ variants show higher supply current than the LMV342MM?
A: The ADA4891-2ARMZ family achieves superior performance specifications (210V/µs slew rate, 105MHz gain bandwidth product) through enhanced internal circuitry, which requires increased quiescent current (4.4mA vs. 107µA). This trade-off is appropriate for applications requiring higher signal fidelity, faster transient response, or lower input offset voltage (2.5mV vs. 700µV). Power budget evaluation is necessary before selection.
Q4: Are the different ADA4891-2ARMZ packaging options (ARMZ, ARMZ-R7, ARMZ-RL) electrically identical?
A: Yes. The ADA4891-2ARMZ, ADA4891-2ARMZ-R7, and ADA4891-2ARMZ-RL are electrically identical. Differences exist only in packaging format: Tube, Cut Tape & Digi-Reel, and Tape & Reel respectively. Selection depends on manufacturing process requirements and inventory management practices.
Q5: What is the minimum supply voltage requirement for the BU7486FVM-TR compared to the LMV342MM?
A: The BU7486FVM-TR requires a minimum supply voltage of 3V, whereas the LMV342MM operates at 2.7V minimum. Applications operating below 3V cannot use the BU7486FVM-TR. The BU7266 series maintains 1.8V minimum supply voltage, providing greater flexibility for low-voltage applications.
Q6: Can the LMV358M8G-13 be used in applications requiring the full -40°C to 125°C temperature range?
A: Yes. The LMV358M8G-13 maintains the -40°C to 125°C operating temperature range of the original LMV342MM. However, this part carries a moisture sensitivity level (MSL) rating of 3 (168 Hours), requiring controlled storage and handling conditions. Verify that your manufacturing environment meets MSL-3 requirements before selection.
Q7: Which substitute part provides the lowest power consumption?
A: The BU7266FVM-TR and BU7266SFVM-TR provide the lowest supply current at 700nA, approximately 150 times lower than the LMV342MM. These parts are optimized for battery-powered and energy-harvesting applications. Trade-offs include reduced bandwidth (4kHz) and slew rate (0.0024V/µs), limiting use to low-frequency signal processing.
Q8: What packaging format compatibility exists between the LMV342MM and substitute parts?
A: The LMV342MM uses an 8-VSSOP package. Substitute parts employ 8-TSSOP or 8-MSOP packages with identical pin counts and similar footprint dimensions (0.118" width for TSSOP/MSOP vs. 0.110" for some MSOP variants). Verify PCB footprint compatibility before layout finalization. Pin assignments are functionally equivalent across all recommended substitutes.
Q9: Which substitute parts carry RoHS3 compliance certification?
A: All substitute parts except LMV342MM/NOPB carry RoHS3 compliance: ADA4891-2ARMZ series, BU7266FVM-TR, BU7266SFVM-TR, BU7486FVM-TR, LMR358FVJ-GE2, LMV358DMR2G, and LMV358M8G-13. The LMV342MM/NOPB is RoHS non-compliant. Regulatory requirements determine whether RoHS3 compliance is mandatory for your application.
Q10: Can the LMR358FVJ-GE2 be substituted for the LMV342MM in all applications?
A: The LMR358FVJ-GE2 maintains identical slew rate (1V/µs) and similar gain bandwidth product (3MHz vs. 1MHz). However, input bias current increases significantly from 0.02pA to 15nA, and input offset voltage decreases to 100µV. Supply current increases to 210µA. Operating temperature range is limited to -40°C to 85°C. These differences may affect precision analog applications; verify performance requirements before selection.
