Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility):

LMV932MMX/NOPB is the direct equivalent substitute for the obsolete LMV932MMX. This part maintains identical electrical specifications including slew rate (0.42 V/µs), gain bandwidth product (1.5 MHz), supply current (116 µA), and output current (100 mA). The part is manufactured by National Semiconductor and carries Active product status. LMV932MMX/NOPB is ROHS3 compliant and AEC-Q100 qualified for automotive applications, providing enhanced compliance compared to the original obsolete part.

General Purpose Amplifier Substitutes (Extended Temperature Range):

LMV358M8G-13 (Diodes Incorporated) provides full compatibility with the LMV932MMX across the complete -40°C to 125°C operating temperature range. This part maintains the dual-circuit, rail-to-rail configuration in 8-MSOP packaging. While slew rate increases to 1 V/µs and gain bandwidth product reduces to 1 MHz, output current capability remains at 90 mA, supporting most applications. ROHS3 compliance is confirmed.

AD8542ARMZ (Analog Devices Inc.) operates across -40°C to 125°C and provides enhanced performance with 0.92 V/µs slew rate. However, output current is limited to 30 mA and supply current is reduced to 45 µA. This part is suitable for applications where lower output current requirements exist.

General Purpose Amplifier Substitutes (Industrial Temperature Range):

APX358M8G-13 and AZV358MMTR-G1 (both Diodes Incorporated) operate within -40°C to 85°C temperature range. Both maintain dual-circuit, rail-to-rail configuration with 1 V/µs slew rate and 1 MHz gain bandwidth product. APX358M8G-13 provides 90 mA output current; AZV358MMTR-G1 provides 60 mA output current. These parts are suitable for applications not requiring extended temperature operation above 85°C.

MCP6002T-I/MS (Microchip Technology) operates -40°C to 85°C with 0.6 V/µs slew rate and 1 MHz gain bandwidth product. Output current is limited to 23 mA. This part is suitable for low-current applications.

MCP6422-E/MS (Microchip Technology) maintains -40°C to 125°C operation but features significantly reduced performance: 0.05 V/µs slew rate, 90 kHz gain bandwidth product, and 22 mA output current. This part is suitable only for low-frequency, low-current applications.

CMOS Amplifier Alternatives (Specialized Applications):

BU7266FVM-TR and BU7266SFVM-TR (Rohm Semiconductor) are CMOS amplifiers with extremely low supply current (700 nA) and input bias current (1 pA). Operating temperature ranges are -40°C to 85°C and -40°C to 105°C respectively. These parts are unsuitable as direct substitutes due to severely limited output current (4 mA) and gain bandwidth product (4 kHz). Selection is appropriate only for ultra-low-power applications where performance trade-offs are acceptable.

BU7486FVM-TR (Rohm Semiconductor) provides enhanced performance with 10 V/µs slew rate and 10 MHz gain bandwidth product, operating -40°C to 105°C. However, minimum supply voltage is 3V (versus 1.8V for LMV932MMX), and output current is limited to 12 mA. This part is unsuitable as a general substitute.

Frequently Asked Questions (FAQ)

Q: Can LMV932MMX/NOPB be used as a direct replacement for LMV932MMX?

A: Yes. LMV932MMX/NOPB is the direct equivalent with identical electrical specifications. The primary difference is product status (Active versus Obsolete) and enhanced compliance certifications (ROHS3 and AEC-Q100). No circuit modifications are required.

Q: What is the key difference between general-purpose and CMOS amplifier substitutes?

A: General-purpose amplifiers (LMV358M8G-13, AD8542ARMZ, APX358M8G-13, AZV358MMTR-G1, MCP6002T-I/MS, MCP6422-E/MS) maintain output current capability of 22 mA or higher and are suitable for standard signal conditioning applications. CMOS amplifiers (BU7266FVM-TR, BU7266SFVM-TR, BU7486FVM-TR) feature extremely low supply current but severely limited output current (4-12 mA) and are suitable only for ultra-low-power or high-impedance applications.

Q: Which substitute part maintains the full -40°C to 125°C operating temperature range?

A: Three parts maintain the complete -40°C to 125°C range: LMV932MMX/NOPB (direct equivalent), LMV358M8G-13, AD8542ARMZ, and MCP6422-E/MS. LMV932MMX/NOPB and LMV358M8G-13 are recommended for applications requiring full temperature range operation with adequate output current (90-100 mA).

Q: Are all substitute parts available in 8-VSSOP packaging?

A: No. The original LMV932MMX uses 8-VSSOP packaging. Most active substitutes are available in 8-MSOP packaging, which is mechanically compatible (0.118" width, 3.00mm) but electrically identical. Verify PCB footprint compatibility before selection. BU7266FVM-TR and BU7266SFVM-TR are available in 8-VSSOP or 8-MSOP (0.110", 2.80mm width).

Q: What output current capability is required for substitution?

A: The LMV932MMX provides 100 mA output current per channel. Substitute parts must provide minimum 60 mA output current for direct substitution in most applications. Parts with lower output current (MCP6002T-I/MS at 23 mA, MCP6422-E/MS at 22 mA, CMOS variants at 4-12 mA) require circuit redesign and are suitable only for specific low-current applications.

Q: Can MCP6422-E/MS replace LMV932MMX in all applications?

A: No. While MCP6422-E/MS maintains the -40°C to 125°C temperature range and dual-circuit rail-to-rail configuration, it features significantly reduced performance: 0.05 V/µs slew rate (versus 0.42 V/µs), 90 kHz gain bandwidth product (versus 1.5 MHz), and 22 mA output current (versus 100 mA). This part is suitable only for low-frequency, low-current signal conditioning applications.

Q: What compliance certifications should be verified for new designs?

A: All active substitute parts carry ROHS3 compliance and REACH Unaffected status. LMV932MMX/NOPB additionally carries AEC-Q100 automotive qualification. For automotive applications, LMV932MMX/NOPB is the recommended substitute. For industrial applications, any ROHS3-compliant part is acceptable.

Q: How does supply current affect power consumption in battery-powered applications?

A: Supply current ranges from 0.7 µA (BU7266 CMOS variants) to 210 µA (AZV358MMTR-G1). For battery-powered applications, CMOS variants (BU7266FVM-TR, BU7266SFVM-TR) minimize power consumption but sacrifice output current capability. General-purpose variants (LMV358M8G-13, APX358M8G-13) provide balanced performance at 190 µA supply current.

Q: Is input bias current a critical parameter for substitution?

A: Input bias current ranges from 0.001 nA (CMOS and MCP6002/MCP6422 variants) to 15 nA (AZV358MMTR-G1). For high-impedance input circuits, lower input bias current is preferred. For standard signal conditioning, input bias current differences are negligible. Verify application requirements before selection.
