LMC6482AIN Equivalent & Substitute Parts

Part Overview

The LMC6482AIN is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, designed for rail-to-rail output applications in low-power analog signal processing circuits. The device integrates two independent amplifier circuits in an 8-pin DIP package, suitable for through-hole mounting on printed circuit boards.

The LMC6482AIN is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability for production, and support long-term system maintenance where original components are no longer readily available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMC6482AIN is determined by strict equivalence across all electrical and mechanical parameters. The critical parameters that define substitutability are:

Electrical Parameters:

• Amplifier Type: CMOS
• Number of Circuits: 2 (dual-channel configuration)
• Output Type: Rail-to-Rail
• Slew Rate: 1.3 V/µs
• Gain Bandwidth Product: 1.5 MHz
• Input Bias Current: 0.02 pA
• Input Offset Voltage: 110 µV
• Supply Current: 1.3 mA per channel
• Output Current per Channel: 30 mA
• Supply Voltage Range: 3 V to 15.5 V
• Operating Temperature: -40°C to 85°C

Mechanical Parameters:

• Mounting Type: Through Hole
• Package: 8-DIP (0.300", 7.62mm)
• Supplier Device Package: 8-PDIP

All substitute parts must match these parameters exactly. Packaging format differences (such as tube versus bulk) do not affect electrical or mechanical compatibility and are therefore acceptable variations within the same base product number.

Parameter Comparison

Engineering Selection Recommendations

The LMC6482AIN/NOPB is a direct functional equivalent to the LMC6482AIN. Both parts share identical electrical specifications and mechanical packaging, ensuring pin-for-pin and functional compatibility in circuit applications.

Product Status Consideration: The LMC6482AIN is classified as obsolete, while the LMC6482AIN/NOPB is active. For new designs, production runs, and long-term component sourcing, the LMC6482AIN/NOPB is the appropriate selection due to its active product status and continued availability through distribution channels.

Compliance Consideration: The LMC6482AIN/NOPB carries ROHS3 compliance certification, whereas the original LMC6482AIN is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the LMC6482AIN/NOPB is the mandated choice.

Packaging Format: The LMC6482AIN/NOPB is supplied in tube packaging, while the original part is supplied in bulk format. This difference affects handling and storage procedures but does not impact electrical or mechanical performance. Tube packaging provides improved component protection during transport and storage.

Both parts are manufactured by Texas Instruments and share the same base product number (LMC6482), confirming their equivalence within the manufacturer's product line.

Frequently Asked Questions (FAQ)

Q: Can the LMC6482AIN/NOPB be used as a direct replacement for the LMC6482AIN in existing circuit designs?

A: Yes. The LMC6482AIN/NOPB is electrically and mechanically identical to the LMC6482AIN. All electrical parameters, pin configuration, and package dimensions are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between the LMC6482AIN and LMC6482AIN/NOPB?

A: The primary differences are product status and compliance certification. The LMC6482AIN is obsolete and RoHS non-compliant. The LMC6482AIN/NOPB is an active product with ROHS3 compliance. The "/NOPB" suffix indicates lead-free solder ball packaging. Electrical and mechanical specifications are identical.

Q: Why is the LMC6482AIN classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, technology evolution, and production decisions. The LMC6482AIN has been superseded by the active LMC6482AIN/NOPB variant, which incorporates modern compliance standards.

Q: Is the 8-DIP package compatible with both through-hole and surface-mount PCB designs?

A: The 8-DIP package is designed for through-hole mounting only. The 0.300" (7.62mm) lead spacing and pin configuration are specific to through-hole assembly. Surface-mount applications require alternative package formats not covered by this part number.

Q: What is the significance of the "/NOPB" designation in the part number?

A: The "/NOPB" suffix indicates that the component is manufactured without lead-based solder and meets lead-free manufacturing standards. This designation is associated with RoHS compliance and modern environmental regulations.

Q: Are there inventory differences between the LMC6482AIN and LMC6482AIN/NOPB?

A: Yes. The LMC6482AIN has 1429 pieces in stock, while the LMC6482AIN/NOPB has 2799 pieces in stock. The higher inventory level for the active product reflects ongoing production and distribution support.

Q: Can the LMC6482AIN be used in new product designs?

A: The LMC6482AIN is obsolete and not recommended for new designs. The LMC6482AIN/NOPB should be selected for all new development to ensure long-term component availability, regulatory compliance, and manufacturer support.

Q: What are the key electrical parameters that define substitutability for this amplifier?

A: Substitutability is determined by matching: amplifier type (CMOS), number of circuits (2), output type (rail-to-rail), slew rate (1.3 V/µs), gain bandwidth product (1.5 MHz), input bias current (0.02 pA), input offset voltage (110 µV), supply current (1.3 mA per channel), output current (30 mA per channel), and supply voltage range (3 V to 15.5 V).

Q: Does packaging format (tube versus bulk) affect circuit performance?

A: No. Packaging format affects only component handling, storage, and logistics. Electrical and mechanical performance are identical regardless of whether the part is supplied in tube or bulk format.
