Substitute Part Grouping Explanation

Substitute parts for the LMC6082IM are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is structured as follows:

Direct Package Equivalent (Same Manufacturer): The LMC6082IM/NOPB is a direct Texas Instruments equivalent with identical electrical specifications and 8-SOIC packaging. This part maintains all key parameters including slew rate (1.5V/µs), gain bandwidth product (1.3 MHz), input bias current (0.01 pA), and output current per channel (34 mA). The primary distinction is product status (Last Time Buy versus Obsolete) and compliance status (RoHS3 Compliant versus RoHS non-compliant).

Cross-Manufacturer Substitute (STMicroelectronics): The TS912AIDT from STMicroelectronics is classified as a manufacturer-recommended substitute. This part shares the same 8-SOIC package footprint and dual-channel CMOS amplifier architecture. Electrical parameters remain within compatible ranges: slew rate of 1.3V/µs (versus 1.5V/µs), gain bandwidth product of 1.4 MHz (versus 1.3 MHz), and output current per channel of 75 mA (versus 34 mA). The TS912AIDT operates across a wider supply voltage range (2.7V to 16V versus 4.5V to 15.5V) and extended temperature range (-40°C to 125°C versus -40°C to 85°C). This part carries Active product status, AEC-Q100 automotive qualification, and RoHS3 compliance.

Substitution Criteria: All substitute parts must satisfy the following mandatory conditions:

• Identical package type: 8-SOIC surface mount
• Dual-channel CMOS amplifier configuration
• Rail-to-rail output capability
• Supply voltage range compatibility or superset coverage
• Output current capability equal to or exceeding 34 mA per channel
• Input bias current and offset voltage within acceptable design tolerances

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance): The LMC6082IM/NOPB is the appropriate selection when maintaining identical electrical specifications is required. This part provides complete functional equivalence with the original LMC6082IM while offering improved compliance status (RoHS3 Compliant) and extended product availability (Last Time Buy status). The LMC6082IM/NOPB is suitable for applications where the original design parameters must be preserved without modification.

For New Designs and Long-Term Production: The TS912AIDT from STMicroelectronics is the recommended selection for new product development and applications requiring extended production life. This part offers Active product status, ensuring long-term availability and supply chain stability. The TS912AIDT provides superior compliance certifications including RoHS3 compliance and AEC-Q100 automotive qualification. The extended operating temperature range (-40°C to 125°C) accommodates demanding thermal environments. Enhanced output current capability (75 mA per channel versus 34 mA) provides additional design margin for output loading. Reduced supply current consumption (0.23 mA versus 1.1 mA across both channels) improves power efficiency in battery-powered applications.

Compliance Considerations: Both substitute parts satisfy RoHS3 compliance requirements, addressing regulatory requirements for new product certifications. The TS912AIDT carries AEC-Q100 automotive qualification, enabling use in automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can the LMC6082IM/NOPB be used as a direct drop-in replacement for the LMC6082IM?

A: Yes. The LMC6082IM/NOPB maintains identical electrical specifications, package configuration (8-SOIC), and pinout. Both parts are manufactured by Texas Instruments and share the same base product number (LMC6082). The primary differences are product status and compliance certifications, not functional performance.

Q: What are the key differences between the LMC6082IM and TS912AIDT?

A: Both parts share the same 8-SOIC package and dual-channel CMOS amplifier architecture. The TS912AIDT offers a wider supply voltage range (2.7V to 16V versus 4.5V to 15.5V), extended operating temperature range (-40°C to 125°C versus -40°C to 85°C), higher output current per channel (75 mA versus 34 mA), and lower supply current consumption (0.23 mA versus 1.1 mA). The TS912AIDT has Active product status and carries AEC-Q100 automotive qualification. Input bias current is higher (1 pA versus 0.01 pA) and input offset voltage is lower (5 mV versus 150 µV).

Q: Is the TS912AIDT suitable for applications originally designed for the LMC6082IM?

A: The TS912AIDT is electrically compatible with the LMC6082IM for most applications. The identical 8-SOIC package enables direct PCB footprint compatibility. The TS912AIDT's enhanced output current capability and wider supply voltage range provide design margin. However, applications with strict input offset voltage or input bias current specifications may require circuit verification, as the TS912AIDT exhibits different input characteristics (5 mV offset versus 150 µV, and 1 pA bias current versus 0.01 pA).

Q: What is the significance of the product status classifications?

A: LMC6082IM is classified as Obsolete, indicating discontinued manufacturing and limited availability. LMC6082IM/NOPB carries Last Time Buy status, indicating final production runs with defined end-of-life dates. TS912AIDT is classified as Active, indicating ongoing production and long-term availability. For new designs and applications requiring extended production life, Active status parts are preferred.

Q: Are all three parts RoHS compliant?

A: The LMC6082IM is RoHS non-compliant. Both LMC6082IM/NOPB and TS912AIDT are RoHS3 compliant, meeting current regulatory requirements for electronic components in regulated markets.

Q: Does the TS912AIDT require circuit modifications when substituting for the LMC6082IM?

A: No circuit modifications are required for basic substitution. Both parts share identical pinout and 8-SOIC package configuration. However, applications with specific input offset voltage or input bias current requirements should verify circuit performance, as these parameters differ between the parts. The TS912AIDT's higher output current capability may eliminate the need for output buffering in some designs.

Q: What is the significance of AEC-Q100 qualification on the TS912AIDT?

A: AEC-Q100 qualification indicates the TS912AIDT meets automotive industry reliability and quality standards. This qualification enables use in automotive applications and high-reliability environments where component qualification is mandatory. The LMC6082IM and LMC6082IM/NOPB do not carry automotive qualification.
