Substitute Part Grouping Explanation
Substitution of the LMV932DR2G is determined by alignment across the following critical parameters:
Mandatory Compatibility Criteria:
- Dual-channel configuration (2 circuits)
- Rail-to-rail output capability
- CMOS amplifier topology
- Surface mount technology
- Operating temperature range support
- Supply voltage span compatibility (minimum 1.8 V to maximum 5 V or higher)
- RoHS3 compliance and MSL 1 rating
Performance Parameter Ranges: Substitute parts are grouped based on slew rate, gain bandwidth product, input bias current, supply current, and output current capabilities. Parts with lower performance specifications (reduced slew rate, lower bandwidth) are suitable for applications with relaxed frequency response requirements. Parts with higher performance specifications provide enhanced bandwidth and slew rate performance for demanding signal processing applications.
Package Considerations: The primary part uses 8-SOIC packaging (0.154" width, 3.90mm). Substitute parts may employ 8-SOIC or 8-SOP packaging formats. Physical package dimensions must be verified for PCB layout compatibility.

Frequently Asked Questions (FAQ)
Q: Can BU7262F-E2 replace LMV932DR2G in all applications?
A: BU7262F-E2 is electrically compatible as a dual-channel rail-to-rail CMOS amplifier with higher bandwidth (2 MHz vs. 1.5 MHz) and faster slew rate (1.1 V/µs vs. 0.35 V/µs). However, the operating temperature range is limited to -40°C to 85°C compared to LMV932DR2G at -40°C to 125°C. Substitution is valid only for applications operating within the -40°C to 85°C range. Package dimensions differ (8-SOP 4.40mm vs. 8-SOIC 3.90mm), requiring PCB layout verification.
Q: What is the difference between BU7262F-E2 and BU7262SF-E2?
A: Both parts are electrically identical with 2 MHz bandwidth and 1.1 V/µs slew rate. BU7262SF-E2 extends the operating temperature range to -40°C to 105°C and uses Tape & Reel packaging, while BU7262F-E2 operates to -40°C to 85°C with Cut Tape & Digi-Reel packaging. Selection depends on temperature requirements and packaging format compatibility with assembly processes.
Q: Is ISL28213FBZ a direct replacement for LMV932DR2G?
A: ISL28213FBZ maintains the extended temperature range (-40°C to 125°C) and uses identical 8-SOIC packaging (3.90mm width), providing direct PCB footprint compatibility. However, ISL28213FBZ is classified as a General Purpose amplifier rather than CMOS type, with 1 V/µs slew rate and 2 MHz bandwidth. Input bias current is 3 pA versus 1 nA for LMV932DR2G. Electrical performance is compatible for most applications, but device classification and input bias characteristics differ.
Q: When should BU7266F-E2 or BU7266SF-E2 be selected?
A: These ultra-low power devices (700 nA supply current) are selected exclusively for battery-powered or energy-harvesting applications where power consumption is the primary design constraint. The 4 kHz bandwidth and 0.0024 V/µs slew rate limit use to DC signal conditioning, audio frequency processing, or sensor signal amplification. These parts are unsuitable for applications requiring bandwidth above 4 kHz.
Q: What are the package compatibility considerations?
A: LMV932DR2G uses 8-SOIC packaging with 0.154" width (3.90mm). ISL28213FBZ, ISL28214FBZ, and LMR932FJ-GE2 maintain this 3.90mm width, providing direct footprint compatibility. BU7242F-E2, BU7262F-E2, BU7262SF-E2, BU7266F-E2, BU7266SF-E2, BU7486F-E2, and LMR932F-GE2 use 8-SOP packaging with 0.173" width (4.40mm), requiring PCB layout modification. Verify pad spacing and trace routing before substitution.
Q: Does supply voltage range affect substitution decisions?
A: LMV932DR2G operates from 1.8 V to 5 V. Most substitute parts support 1.8 V to 5.5 V, providing extended upper voltage margin. Exception: BU7486F-E2 requires minimum 3 V supply, incompatible with 1.8 V to 3 V applications. Verify circuit supply architecture before selecting BU7486F-E2.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching LMV932DR2G environmental and regulatory specifications. No additional compliance verification is required for standard manufacturing environments.
Q: How do input bias current differences affect circuit design?
A: LMV932DR2G specifies 1 nA input bias current. Most Rohm Semiconductor substitutes (BU7242F-E2, BU7262F-E2, BU7262SF-E2, BU7266F-E2, BU7266SF-E2, BU7486F-E2) specify 1 pA, representing 1000-fold reduction. Renesas ISL28213FBZ and ISL28214FBZ specify 3 pA. Lower input bias current reduces input offset voltage drift and improves precision in high-impedance signal conditioning circuits. LMR932F-GE2 and LMR932FJ-GE2 specify 5 nA, intermediate between primary and substitute parts.
Q: What output current capability differences exist?
A: LMV932DR2G provides 80 mA per channel. ISL28214FBZ provides 31 mA, ISL28213FBZ provides 22 mA, and LMR932F-GE2/LMR932FJ-GE2 provide 90 mA. Rohm BU7242F-E2, BU7262F-E2, BU7262SF-E2, and BU7486F-E2 provide 12 mA. BU7266F-E2 and BU7266SF-E2 provide 4 mA. Output current capability must match load impedance requirements. Lower output current parts are unsuitable for driving low-impedance loads or capacitive loads requiring high transient current.
