- Rail-to-rail output capability
- Supply voltage range encompassing 1.8V to 5.5V minimum
- Slew rate and gain-bandwidth product within acceptable operational margins
- Input bias current and input offset voltage specifications compatible with signal chain requirements
- Output current capability of at least 100 mA per channel
- Operating temperature range supporting -40°C to 125°C or equivalent industrial range
Mechanical Compatibility Requirements:
- Surface-mount package format (8-pin TSSOP or 8-pin MSOP)
- Package body dimensions compatible with 0.118" width specification
- Pin configuration matching standard 8-pin dual-amplifier layout
Compliance Requirements:

Engineering Selection Recommendations
Direct Equivalents (Identical Electrical Specifications):
LMV932MM/NOPB is the direct equivalent of LMV932MM, differing only in packaging format (Tape & Reel versus Cut Tape). Both devices are manufactured by Texas Instruments with identical electrical characteristics. LMV932MM/NOPB is currently in Active product status with higher inventory availability (23,200 units), making it the preferred replacement for LMV932MM applications. REACH status differs (Unaffected versus Affected), which may impact supply chain compliance documentation.
LMV932MMX/NOPB, manufactured by National Semiconductor, provides identical electrical specifications to LMV932MM with the addition of AEC-Q100 automotive qualification. This part is suitable for applications requiring automotive-grade components and operates across the same temperature range (-40°C to 125°C). Product status is Active with 9,250 units in inventory.
Functional Alternatives (Compatible Electrical Performance):
ISL28213FUZ, manufactured by Renesas Electronics Corporation, meets all critical substitution criteria with enhanced performance characteristics. This device maintains the 1.8V to 5.5V supply range and -40°C to 125°C operating temperature, ensuring thermal compatibility. The ISL28213FUZ features superior input offset voltage (500 µV versus 1 mV) and lower input bias current (3 pA versus 14 nA), providing improved signal fidelity. Slew rate is increased to 1 V/µs and gain-bandwidth product to 2 MHz, supporting higher-frequency applications. Output current per channel is reduced to 22 mA, which may limit applications requiring the full 100 mA output capability of the LMV932MM. Moisture sensitivity level is 2 (1 Year), requiring controlled storage conditions.
LMV358DMR2G, manufactured by onsemi, is a voltage feedback amplifier with dual circuits and rail-to-rail output. This device operates across 2.7V to 5.5V supply range, which does not support the 1.8V minimum specification of LMV932MM. Operating temperature range is limited to -40°C to 85°C, reducing thermal compatibility. Output current capability is enhanced to 160 mA per channel. This part is suitable only for applications not requiring 1.8V operation or extended temperature range above 85°C.
Compliance and Availability Considerations:
All substitute parts listed are ROHS3 compliant and carry EAR99 ECCN classification. LMV932MM/NOPB and LMV932MMX/NOPB maintain unlimited moisture sensitivity (MSL 1), eliminating special storage requirements. ISL28213FUZ requires 1-year shelf life management due to MSL 2 rating. LMV358DMR2G offers the highest inventory availability (34,690 units) among all alternatives.
Frequently Asked Questions (FAQ)
Q: Can LMV932MM/NOPB be used as a direct replacement for LMV932MM?
A: Yes. LMV932MM/NOPB is electrically identical to LMV932MM, with all specifications matching exactly. The difference is packaging format: LMV932MM is supplied in Cut Tape (CT) & Digi-Reel format, while LMV932MM/NOPB is supplied in Tape & Reel (TR) format. Both are manufactured by Texas Instruments and are pin-compatible. LMV932MM/NOPB is currently in Active product status with higher inventory availability.
Q: What is the difference between LMV932MMX/NOPB and LMV932MM?
A: LMV932MMX/NOPB is manufactured by National Semiconductor and provides identical electrical specifications to LMV932MM. The key distinction is AEC-Q100 automotive qualification, making it suitable for automotive applications. Both devices operate across -40°C to 125°C and support 1.8V to 5.5V supply range. LMV932MMX/NOPB is recommended for designs requiring automotive-grade components.
Q: Is ISL28213FUZ a suitable replacement for LMV932MM?
A: ISL28213FUZ is functionally compatible with LMV932MM for most applications. Both devices feature dual circuits, rail-to-rail output, and operate across 1.8V to 5.5V supply range with -40°C to 125°C temperature range. ISL28213FUZ offers superior performance with lower input offset voltage (500 µV versus 1 mV) and lower input bias current (3 pA versus 14 nA). However, output current per channel is reduced to 22 mA compared to 100 mA for LMV932MM. ISL28213FUZ is suitable only for applications not requiring high output current capability. Moisture sensitivity level is 2, requiring 1-year shelf life management.
Q: Can LMV358DMR2G replace LMV932MM?
A: LMV358DMR2G is not a direct replacement for LMV932MM due to two critical limitations. First, the minimum supply voltage is 2.7V, which does not support the 1.8V minimum specification of LMV932MM. Second, the operating temperature range is limited to -40°C to 85°C, which does not support the extended upper temperature of 125°C. LMV358DMR2G is suitable only for applications operating above 2.7V and below 85°C. This device offers enhanced output current capability (160 mA per channel) and is available in high inventory quantities.
Q: What are the package compatibility considerations for LMV932MM substitutes?
A: LMV932MM is supplied in 8-VSSOP package format. LMV932MM/NOPB and LMV932MMX/NOPB maintain the same 8-VSSOP package. Alternative parts such as AZV358MMTR-E1, ISL28213FUZ, and LMV358DMR2G use 8-MSOP package format. While both 8-VSSOP and 8-MSOP are 8-pin surface-mount packages with similar pin pitch, physical dimensions differ slightly (8-VSSOP is 0.118" width, 8-MSOP is 0.118" width for some variants). PCB layout and footprint must be verified before substitution. Pin configuration is standard for dual-amplifier devices and is compatible across all listed parts.
Q: What is the significance of Moisture Sensitivity Level (MSL) in selecting a substitute?
A: Moisture Sensitivity Level indicates the maximum shelf life and storage conditions required for surface-mount components. LMV932MM, LMV932MM/NOPB, and LMV932MMX/NOPB have MSL 1 (Unlimited), requiring no special storage conditions. ISL28213FUZ has MSL 2 (1 Year), requiring storage in controlled humidity environments and limiting shelf life to one year from manufacturing. If extended shelf life or simplified storage procedures are required, MSL 1 parts are preferred. MSL 2 parts require bake-out procedures before reflow soldering if storage time exceeds specified limits.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed—LMV932MM/NOPB, LMV932MMX/NOPB, AZV358MMTR-E1, ISL28213FUZ, and LMV358DMR2G—are ROHS3 compliant. This ensures compliance with European Union Restriction of Hazardous Substances regulations. All parts carry EAR99 ECCN classification and HTSUS code 8542.33.0001.
Q: What is the inventory status of available substitutes?
A: LMV932MM/NOPB has the highest inventory among direct equivalents with 23,200 units in stock. LMV358DMR2G offers the largest overall inventory with 34,690 units. ISL28213FUZ has limited availability with 1,306 units. LMV932MMX/NOPB has 9,250 units available. For applications requiring immediate availability, LMV358DMR2G or LMV932MM/NOPB are recommended, subject to electrical compatibility verification.
