LMV932IDRE4 Equivalent & Substitute Parts
Part Overview
The LMV932IDRE4 is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in an 8-SOIC surface-mount package. This device delivers rail-to-rail output capability with a 1.5 MHz gain bandwidth product and operates across a 1.8 V to 5 V supply range. The LMV932IDRE4 is classified as obsolete; therefore, identifying active equivalent and substitute parts is essential for ongoing design support, production continuity, and component procurement.

Substitute Part Grouping Explanation
Substitution of the LMV932IDRE4 is determined by the following critical parameters:
Primary Substitution Criteria:
- Amplifier Type: General Purpose
- Number of Circuits: 2
- Output Type: Rail-to-Rail
- Package / Case: 8-SOIC (0.154", 3.90mm Width)
- Mounting Type: Surface Mount
- Supply Voltage Range: Minimum 1.8 V, Maximum ≥ 5 V
- Operating Temperature Range: Minimum -40°C, Maximum ≥ 125°C (preferred)
Secondary Compatibility Factors:
- Slew Rate: ≥ 0.35 V/µs (for signal fidelity in general-purpose applications)
- Gain Bandwidth Product: ≥ 1 MHz (for frequency response compatibility)
- Current - Output / Channel: ≥ 90 mA (for load-driving capability)
- RoHS3 Compliance and MSL Level 1 (for manufacturing and environmental standards)
Substitute parts are grouped into two categories:
Category A: Direct Replacements (Texas Instruments LMV932 Series) Parts LMV932MA/NOPB and LMV932MAX/NOPB are active variants of the same base product number (LMV932) with identical electrical specifications and package geometry. These represent the primary replacement path for the obsolete LMV932IDRE4.
Category B: Functional Equivalents (Alternative Manufacturers) Parts from Rohm Semiconductor (LMR932F-GE2, BU7266F-E2, BU7266SF-E2, BU7486F-E2) and Analog Devices Inc./Maxim Integrated (MAX4246ASA+, MAX4471ESA+, MAX4471ESA+T) and Microchip Technology (MCP6L02T-E/SN) meet the core substitution criteria but exhibit variations in secondary parameters such as slew rate, gain bandwidth product, supply current, or maximum operating temperature. Selection within this category requires application-specific validation.

Engineering Selection Recommendations
Tier 1: Direct Replacement (Recommended)
LMV932MA/NOPB and LMV932MAX/NOPB are the primary substitutes for LMV932IDRE4. Both parts are active products from Texas Instruments with identical electrical specifications and package geometry. The only differences are packaging format (Tube versus Cut Tape & Digi-Reel) and maximum supply voltage (5.5 V versus 5 V). Both maintain ROHS3 compliance, MSL Level 1, and the full -40°C to 125°C operating temperature range. LMV932MAX/NOPB offers higher inventory availability (36,900 units) compared to LMV932MA/NOPB (9,420 units).
Tier 2: Functional Equivalents with Minor Parameter Deviations
MAX4246ASA+ (Analog Devices Inc./Maxim Integrated) maintains identical package geometry and operating temperature range but exhibits reduced output current per channel (30 mA versus 100 mA) and higher supply current (375 µA versus 116 µA). This part is suitable for applications with lower output current requirements.
MCP6L02T-E/SN (Microchip Technology) provides improved slew rate (0.6 V/µs versus 0.42 V/µs), lower input bias current (2 pA versus 15 nA), and extended maximum supply voltage (6 V versus 5 V). However, output current per channel is reduced to 20 mA. This part is appropriate for low-bias-current and high-slew-rate applications.
LMR932F-GE2 (Rohm Semiconductor) offers lower input bias current (5 nA) and operates within the same supply voltage range (1.8 V to 5 V). However, the maximum operating temperature is limited to 85°C, and the package width is 4.40 mm (versus 3.90 mm for the original part). This part is not recommended for applications requiring the full -40°C to 125°C temperature range.
Tier 3: Specialized Alternatives
MAX4471ESA+ and MAX4471ESA+T (Analog Devices Inc./Maxim Integrated) feature ultra-low supply current (750 nA) and extremely low input bias current (200 pA), making them suitable for battery-powered and ultra-low-power applications. However, the gain bandwidth product (9 kHz) and slew rate (0.002 V/µs) are significantly reduced, limiting frequency response. These parts are not suitable for general-purpose amplification at the 1.5 MHz bandwidth of the original device.
BU7266F-E2, BU7266SF-E2, and BU7486F-E2 (Rohm Semiconductor) are CMOS amplifiers with different performance profiles. BU7266 variants feature extremely low input bias current (1 pA) but severely limited bandwidth (4 kHz). BU7486F-E2 offers higher slew rate (10 V/µs) and bandwidth (10 MHz) but requires a minimum supply voltage of 3 V and is limited to 85°C or 105°C maximum operating temperature. These parts are not direct functional equivalents and require application-specific evaluation.
Compliance and Certification:
All recommended substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing processes and environmental requirements. All parts carry EAR99 export classification and are REACH unaffected.
Frequently Asked Questions (FAQ)
Q1: Can LMV932MA/NOPB or LMV932MAX/NOPB be used as direct drop-in replacements for LMV932IDRE4?
A: Yes. Both parts are active variants of the LMV932 base product number with identical electrical specifications, package geometry (8-SOIC, 0.154" width), and operating temperature range (-40°C to 125°C). The only differences are packaging format and maximum supply voltage (5.5 V versus 5 V). For applications operating at or below 5 V, these parts are direct replacements.
Q2: What is the difference between LMV932MA/NOPB and LMV932MAX/NOPB?
A: Both parts have identical electrical specifications. The difference is packaging: LMV932MA/NOPB is supplied in Tube format, while LMV932MAX/NOPB is supplied in Cut Tape & Digi-Reel format. LMV932MAX/NOPB has significantly higher inventory availability (36,900 units versus 9,420 units).
Q3: Why is MAX4471ESA+ listed as a substitute if its bandwidth is only 9 kHz?
A: MAX4471ESA+ meets the core substitution criteria (dual general-purpose rail-to-rail amplifier in 8-SOIC package) but is optimized for ultra-low-power applications with 750 nA supply current. It is not functionally equivalent for applications requiring 1.5 MHz bandwidth. Selection of this part requires application-specific validation and is only appropriate for low-frequency, battery-powered designs.
Q4: Can LMR932F-GE2 be used in applications requiring -40°C to 125°C operation?
A: No. LMR932F-GE2 is rated for -40°C to 85°C operation only. It is not suitable for applications requiring the full -40°C to 125°C temperature range of the original LMV932IDRE4.
Q5: What is the significance of the package width difference between 0.154" and 0.173"?
A: The package width difference (3.90 mm versus 4.40 mm) affects PCB layout and component placement. Parts with 0.173" width (such as LMR932F-GE2 and Rohm BU7266/BU7486 variants) may not fit in PCB footprints designed for the original 0.154" width. Physical compatibility must be verified before substitution.
Q6: Which substitute part offers the best performance improvement over LMV932IDRE4?
A: MCP6L02T-E/SN provides improved slew rate (0.6 V/µs versus 0.42 V/µs), significantly lower input bias current (2 pA versus 15 nA), and extended supply voltage range (up to 6 V). However, output current per channel is reduced to 20 mA. Selection depends on application requirements for slew rate, bias current, and output current.
Q7: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed are ROHS3 compliant with MSL Level 1 rating, ensuring compatibility with standard manufacturing processes and environmental regulations.
Q8: What is the inventory status of recommended substitutes?
A: LMV932MAX/NOPB has the highest inventory (36,900 units), followed by MCP6L02T-E/SN (54,941 units). LMV932MA/NOPB has 9,420 units. All recommended Tier 1 and Tier 2 parts have active product status with substantial inventory availability.
