LMV932MAX Equivalent & Substitute Parts

Part Overview

The LMV932MAX is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual-channel rail-to-rail output configuration in an 8-SOIC surface mount package. This device is classified as Last Time Buy, indicating discontinued production with limited availability. The LMV932MAX serves applications requiring low-power, dual-channel amplification across supply voltages from 1.8V to 5.5V with operating temperature range of -40°C to 125°C.

Substitute parts are necessary due to the Last Time Buy status of the LMV932MAX. Alternative components with equivalent or superior electrical characteristics and compatible packaging enable continued system design and production without redesign constraints.

Engineering Selection Recommendations

Primary Recommendation: LMV932MAX/NOPB

The LMV932MAX/NOPB is the direct equivalent of the LMV932MAX, manufactured by Texas Instruments with identical electrical specifications and 8-SOIC packaging. This part maintains Active product status with 36,900 units in stock, providing immediate availability and design continuity. Both parts are ROHS3 compliant with MSL 1 rating. Selection of LMV932MAX/NOPB eliminates all substitution variables and is recommended for applications where the original specification must be preserved without modification.

Secondary Recommendation: AD8542ARZ / AD8542ARZ-REEL / AD8542ARZ-REEL7

The AD8542 series from Analog Devices Inc. provides enhanced performance characteristics while maintaining full compatibility with the LMV932MAX application envelope. Key advantages include significantly reduced input bias current (4 pA versus 14 nA), lower supply current consumption (45 µA versus 116 µA), and extended temperature range to 125°C. All three variants are ROHS3 compliant with MSL 1 rating and Active product status. The AD8542ARZ-REEL and AD8542ARZ-REEL7 variants offer superior inventory availability (33,700 and 23,100 units respectively). These parts are suitable for designs where power consumption reduction or improved input impedance characteristics provide system-level benefits.

Tertiary Recommendation: APX358SG-13 / AZV358MTR-E1

The APX358SG-13 (Diodes Incorporated) and AZV358MTR-E1 (Diodes Incorporated) provide functional alternatives with 8-SOIC packaging and rail-to-rail output. Both maintain ROHS3 compliance and MSL 1 rating with Active product status. However, both parts are limited to -40°C to 85°C operating temperature range, restricting use in applications requiring the full -40°C to 125°C specification of the LMV932MAX. Selection of these alternatives requires verification that the reduced temperature range is acceptable for the target application.

Not Recommended for Direct Substitution: BU7242 and BU7266 Series

The BU7242F-E2, BU7242SF-E2, BU7266F-E2, and BU7266SF-E2 from Rohm Semiconductor are CMOS amplifiers with significantly different electrical characteristics. The BU7266 variants exhibit extremely low bandwidth (4 kHz) and slew rate (0.0024 V/µs), making them unsuitable for general-purpose amplifier applications. The BU7242 variants provide reduced output current capability (12 mA versus 100 mA). These parts are applicable only to specialized low-power, low-frequency applications and should not be selected as general substitutes for the LMV932MAX.

Frequently Asked Questions (FAQ)

Q1: Can LMV932MAX/NOPB be used as a direct replacement for LMV932MAX?

Yes. The LMV932MAX/NOPB is manufactured by Texas Instruments with identical electrical specifications, package configuration, and compliance certifications. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Both parts are suitable for direct substitution without circuit modification. The LMV932MAX/NOPB is recommended due to Active product status and higher inventory availability.

Q2: What are the key differences between AD8542ARZ and LMV932MAX?

The AD8542ARZ maintains compatibility with the LMV932MAX supply voltage range (1.8V to 5.5V) and operating temperature (-40°C to 125°C). Primary differences include: (1) Input bias current reduced from 14 nA to 4 pA, (2) Supply current reduced from 116 µA to 45 µA, (3) Output current capability reduced from 100 mA to 30 mA, (4) Slew rate increased from 0.42 V/µs to 0.92 V/µs, (5) Gain bandwidth product reduced from 1.5 MHz to 1 MHz. Selection depends on whether the application requires the LMV932MAX output current capability or benefits from the AD8542ARZ power consumption reduction.

Q3: Are the Diodes Incorporated APX358SG-13 and AZV358MTR-E1 suitable for all LMV932MAX applications?

Both parts provide 8-SOIC packaging and rail-to-rail output compatible with the LMV932MAX. However, both are limited to -40°C to 85°C operating temperature, which does not cover the full -40°C to 125°C range of the LMV932MAX. These parts are suitable only for applications where the maximum operating temperature does not exceed 85°C. Verification of temperature requirements is mandatory before selection.

Q4: Why are the Rohm BU7242 and BU7266 series not recommended as LMV932MAX substitutes?

The BU7242 series provides only 12 mA output current versus the LMV932MAX 100 mA capability, making it unsuitable for applications requiring higher output drive. The BU7266 series exhibits extremely low bandwidth (4 kHz) and slew rate (0.0024 V/µs), restricting use to specialized low-frequency applications. These parts serve different application categories and should not be selected as general-purpose substitutes.

Q5: What packaging considerations apply when selecting substitute parts?

All recommended substitute parts utilize 8-SOIC surface mount packaging with 0.154" (3.90mm) width, maintaining PCB footprint compatibility with the LMV932MAX. Packaging variants (Tape & Reel, Cut Tape & Digi-Reel®) affect supply chain logistics but do not impact electrical performance or board-level compatibility. Verify packaging availability with your supplier based on production volume requirements.

Q6: Are all substitute parts ROHS3 compliant?

Yes. All substitute parts listed in this document are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the LMV932MAX. All parts are suitable for applications requiring ROHS3 certification and standard PCB assembly processes without special moisture control requirements.

Q7: Which substitute part provides the best power consumption characteristics?

The AD8542ARZ series provides the lowest supply current at 45 µA (x2 channels) compared to the LMV932MAX at 116 µA. This represents a 61% reduction in supply current consumption. The AD8542ARZ series is recommended for battery-powered or power-constrained applications where supply current minimization is a design priority.

Q8: Can substitute parts be mixed within a single design?

Mixing substitute parts within a single design is not recommended. Electrical parameter variations between different substitute parts may result in circuit performance inconsistencies, particularly in applications utilizing multiple amplifier channels or cascaded configurations. Standardize on a single substitute part across all instances within a design.
