LMV712LD Equivalent & Substitute Parts

Part Overview

The LMV712LD is a general-purpose operational amplifier manufactured by Texas Instruments, featuring a 2-circuit rail-to-rail configuration in a 10-WSON (3x3) surface mount package. This device is classified as obsolete, which necessitates identification of active equivalent and substitute components for new designs and production continuity. The LMV712LD operates across a 2.7V to 5.5V supply range with a 5V/µs slew rate and 5MHz gain bandwidth product, making it suitable for low-power analog signal conditioning applications.

Substitute Part Grouping Explanation

Substitution of the LMV712LD is determined by the following critical parameters: dual-circuit configuration, rail-to-rail output capability, 10-WSON (3x3) or compatible 10-DFN (3x3) package footprint, 2.7V to 5.5V supply voltage range, and -40°C to 85°C operating temperature span. The substitute parts are grouped into two categories based on electrical performance characteristics:

Category 1: Direct Functional Equivalent (LMV712LD/NOPB) This is the active production variant of the same base product (LMV712), differing only in packaging format (Tape & Reel) and compliance status (RoHS3 Compliant). All electrical specifications remain identical.

Category 2: Analog Devices LTC60xx Series Substitutes These CMOS amplifiers maintain the same package footprint (10-DFN 3x3), dual-circuit configuration, rail-to-rail output, and supply voltage range. Substitution is valid where the specific slew rate, gain bandwidth product, and operating temperature requirements of the application are met. The LTC6078 series offers lower power consumption and input bias current. The LTC6081 series provides higher slew rate and bandwidth. The LTC6087 series delivers the highest performance metrics.

Engineering Selection Recommendations

Primary Recommendation: LMV712LD/NOPB

For direct replacement in existing designs, LMV712LD/NOPB is the preferred choice. This part maintains 100% electrical and functional equivalence to the obsolete LMV712LD while offering active product status and RoHS3 compliance. The only difference is packaging format (Tape & Reel versus tube). This substitution requires no circuit redesign or performance re-evaluation.

Secondary Recommendations: Analog Devices LTC60xx Series

For new designs or applications where component refresh is acceptable, the Analog Devices LTC6078, LTC6081, and LTC6087 series provide active alternatives with identical package footprints and supply voltage compatibility.

LTC6078 Series Selection Criteria: Select LTC6078CDD#PBF, LTC6078CDD#TRPBF, LTC6078IDD#PBF, or LTC6078IDD#TRPBF when applications require ultra-low input bias current (0.2 pA) and minimal power consumption (55 µA per channel). The significantly lower slew rate (0.05 V/µs) and reduced gain bandwidth product (750 kHz) restrict this series to low-frequency signal conditioning, precision measurement, and battery-powered applications where speed is not critical.

LTC6081 Series Selection Criteria: Select LTC6081CDD#PBF, LTC6081CDD#TRPBF, LTC6081IDD#PBF, or LTC6081IDD#TRPBF for applications requiring moderate performance improvement over LMV712LD. The LTC6081 provides 1 V/µs slew rate and 3.5 MHz bandwidth with ultra-low input bias current. Operating temperature range is 0°C to 70°C for C-grade and -40°C to 85°C for I-grade variants. Power consumption is 330 µA per channel.

LTC6087 Series Selection Criteria: Select LTC6087CDD#PBF when maximum performance is required. The LTC6087 delivers 7.2 V/µs slew rate and 14 MHz gain bandwidth product, exceeding LMV712LD specifications. Input bias current is 1 pA with 330 µV input offset voltage. Supply current is 1.05 mA per channel. This device is suitable for high-speed signal conditioning and precision analog applications.

Compliance Considerations: All recommended substitutes are RoHS3 compliant and REACH unaffected. The LMV712LD/NOPB is the only option for applications requiring strict compliance with the original part specification. Analog Devices alternatives are suitable for new designs subject to modern environmental regulations.

Packaging Format Selection: Tube packaging (#PBF suffix) is appropriate for prototype development and low-volume production. Tape & Reel packaging (#TRPBF or #TR suffix) is required for automated assembly and high-volume manufacturing.

Frequently Asked Questions (FAQ)

Q1: Can LMV712LD/NOPB be used as a direct drop-in replacement for LMV712LD?

A: Yes. LMV712LD/NOPB is electrically and functionally identical to LMV712LD. The only difference is packaging format (Tape & Reel versus tube). No circuit modifications are required. This is the recommended substitution path for existing designs.

Q2: What are the key differences between LTC6078 and LMV712LD?

A: The LTC6078 offers significantly lower input bias current (0.2 pA versus 5.5 pA) and reduced power consumption (55 µA versus 1.22 mA per channel). However, it provides substantially lower slew rate (0.05 V/µs versus 5 V/µs) and reduced gain bandwidth product (750 kHz versus 5 MHz). The LTC6078 is suitable only for low-frequency applications where speed is not critical.

Q3: Which substitute part most closely matches LMV712LD performance?

A: LTC6087CDD#PBF exceeds LMV712LD specifications in slew rate (7.2 V/µs versus 5 V/µs) and gain bandwidth product (14 MHz versus 5 MHz). It maintains compatible supply voltage range, package footprint, and dual-circuit configuration. This is the highest-performance substitute available.

Q4: Are all substitute parts compatible with the 10-WSON (3x3) footprint?

A: The LMV712LD uses a 10-WSON (3x3) package. Analog Devices substitutes use a 10-DFN (3x3) package. While the physical dimensions and pin assignments are compatible for PCB layout purposes, the package designations differ. Verify PCB footprint compatibility with component datasheets before finalizing designs.

Q5: What is the operating temperature difference between LTC6081CDD and LTC6081IDD?

A: LTC6081CDD operates from 0°C to 70°C (commercial grade). LTC6081IDD operates from -40°C to 85°C (industrial grade). For applications requiring full -40°C to 85°C range, select LTC6081IDD variants.

Q6: Can LTC6078 be used in applications originally designed for LMV712LD?

A: LTC6078 substitution is valid only if the application does not require the slew rate and bandwidth of the original design. Applications limited to frequencies below 750 kHz and slew rates below 0.05 V/µs can use LTC6078. High-speed signal conditioning, audio amplification, and precision measurement applications requiring 5 V/µs or higher slew rates must use LTC6081 or LTC6087 alternatives.

Q7: What is the difference between tube and Tape & Reel packaging?

A: Tube packaging (#PBF suffix) contains individual components in a plastic tube, suitable for manual assembly and prototype development. Tape & Reel packaging (#TRPBF or #TR suffix) provides components on continuous carrier tape for automated pick-and-place assembly. Tape & Reel is required for high-volume production.

Q8: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitutes (LMV712LD/NOPB and all Analog Devices LTC60xx variants) are RoHS3 compliant. The original LMV712LD is RoHS non-compliant. For applications subject to RoHS requirements, substitution is mandatory.

Q9: What is the inventory status of substitute parts?

A: LMV712LD/NOPB has 15,300 pieces in stock. LTC6078 variants range from 1,366 to 6,742 pieces. LTC6081 variants range from 1,718 to 2,960 pieces. LTC6087CDD#PBF has 2,071 pieces in stock. Verify current availability with your supplier before finalizing procurement.

Q10: Can multiple substitute parts be used interchangeably within a single design?

A: No. Each substitute part has distinct electrical characteristics. Once a specific substitute is selected for a design, all instances of that component must use the same part number. Mixing different substitute parts in a single circuit is not recommended without detailed circuit analysis and performance validation.
