LMC6482IN CMOS Dual Amplifier Equivalent & Substitute Parts

Part Overview

The LMC6482IN is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, housed in an 8-pin DIP package. This device features rail-to-rail output capability and is designed for low-power, general-purpose amplification applications. The LMC6482IN is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and component procurement. Substitute parts must maintain compatibility across electrical performance parameters, mechanical packaging, and thermal operating ranges to ensure functional equivalence in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMC6482IN is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Dual-channel CMOS amplifier architecture
• Rail-to-rail output configuration
• 8-pin DIP through-hole package (0.300", 7.62mm)
• Supply voltage range compatibility (minimum 3V, maximum 15.5V)
• Operating temperature range coverage (-40°C to 85°C minimum)
• Slew rate and gain-bandwidth product within acceptable operational margins
• Input bias current and input offset voltage specifications

Substitute Classification:

Direct Manufacturer Equivalent: LMC6482IN/NOPB is the active production variant of the LMC6482IN, manufactured by Texas Instruments with identical electrical specifications and packaging. This part differs only in packaging format (Tube vs. standard) and product status (Active vs. Obsolete).

Cross-Manufacturer Alternatives: ICL7621BCPA+ and ICL7621DCPA+ are manufactured by Analog Devices Inc./Maxim Integrated. These parts maintain the dual-channel CMOS architecture, rail-to-rail output, and 8-DIP package configuration. Electrical performance parameters differ within acceptable ranges for general-purpose amplification applications.

Parameter Comparison

Engineering Selection Recommendations

LMC6482IN/NOPB (Texas Instruments)

LMC6482IN/NOPB is the direct active-production equivalent of the LMC6482IN. This part maintains identical electrical specifications and mechanical packaging. The primary distinction is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 Compliant vs. Non-compliant). Selection of LMC6482IN/NOPB is appropriate for designs requiring exact electrical equivalence and ongoing manufacturer support. This part is suitable for applications where the extended operating temperature range (-40°C to 85°C) and specific input bias current specification (0.02 pA) are design requirements.

ICL7621BCPA+ (Analog Devices Inc./Maxim Integrated)

ICL7621BCPA+ is an active cross-manufacturer substitute with compatible dual-channel CMOS architecture and rail-to-rail output in 8-DIP packaging. This part exhibits improved slew rate (1.6 V/µs vs. 1.3 V/µs) and superior input offset voltage specification (5 mV vs. 110 µV). The operating temperature range is narrower (0°C to 70°C), which may limit applicability in extended-temperature environments. Supply voltage range compatibility is maintained (2V to 16V). This part is suitable for general-purpose amplification applications where the reduced operating temperature range is acceptable and improved slew rate performance is beneficial.

ICL7621DCPA+ (Analog Devices Inc./Maxim Integrated)

ICL7621DCPA+ is an active cross-manufacturer substitute with specifications identical to ICL7621BCPA+ except for input offset voltage (15 mV vs. 5 mV). This part is suitable for applications where the ICL7621BCPA+ input offset voltage specification is unnecessarily stringent. The narrower operating temperature range (0°C to 70°C) applies to this part as well. Selection between ICL7621BCPA+ and ICL7621DCPA+ depends on input offset voltage tolerance requirements in the target application.

Compliance Considerations

LMC6482IN/NOPB, ICL7621BCPA+, and ICL7621DCPA+ are all ROHS3 compliant and REACH unaffected. The original LMC6482IN is RoHS non-compliant. For applications subject to RoHS or REACH regulatory requirements, substitute parts must be selected from the compliant alternatives.

Frequently Asked Questions (FAQ)

Q: Can LMC6482IN/NOPB be used as a direct replacement for LMC6482IN?

A: Yes. LMC6482IN/NOPB is the active production equivalent manufactured by Texas Instruments with identical electrical specifications, package configuration, and pin assignment. The parts are electrically and mechanically interchangeable. The primary differences are product status (Active vs. Obsolete) and RoHS compliance status.

Q: What are the key differences between LMC6482IN and ICL7621BCPA+?

A: Both parts are dual-channel CMOS amplifiers in 8-DIP packages with rail-to-rail output. ICL7621BCPA+ offers improved slew rate (1.6 V/µs vs. 1.3 V/µs) and superior input offset voltage (5 mV vs. 110 µV). The operating temperature range is narrower for ICL7621BCPA+ (0°C to 70°C vs. -40°C to 85°C). Supply voltage ranges are compatible (2V to 16V for ICL7621BCPA+ vs. 3V to 15.5V for LMC6482IN).

Q: Are ICL7621BCPA+ and ICL7621DCPA+ interchangeable?

A: ICL7621BCPA+ and ICL7621DCPA+ are functionally equivalent except for input offset voltage specification (5 mV vs. 15 mV). Both parts share identical slew rate, gain-bandwidth product, supply current, supply voltage range, operating temperature range, and package configuration. Selection between these parts depends on input offset voltage tolerance requirements in the specific application circuit.

Q: What is the impact of the narrower operating temperature range in ICL7621 parts?

A: ICL7621BCPA+ and ICL7621DCPA+ operate from 0°C to 70°C, compared to -40°C to 85°C for LMC6482IN and LMC6482IN/NOPB. Applications requiring operation below 0°C or above 70°C must use LMC6482IN or LMC6482IN/NOPB. Applications with operating temperature requirements within 0°C to 70°C can use either part family.

Q: Are all substitute parts RoHS compliant?

A: LMC6482IN/NOPB, ICL7621BCPA+, and ICL7621DCPA+ are all ROHS3 compliant. The original LMC6482IN is RoHS non-compliant. For applications subject to RoHS regulatory requirements, substitute parts must be selected from the compliant alternatives listed above.

Q: What packaging formats are available for these parts?

A: All parts in this comparison are supplied in 8-pin DIP through-hole packages (0.300", 7.62mm). LMC6482IN/NOPB is supplied in Tube packaging format. Mechanical compatibility is maintained across all parts for through-hole PCB assembly.

Q: Can ICL7621 parts be used in applications originally designed for LMC6482IN?

A: ICL7621BCPA+ and ICL7621DCPA+ can be used in applications originally designed for LMC6482IN provided that the operating temperature range requirement does not exceed 0°C to 70°C. The dual-channel CMOS architecture, rail-to-rail output, 8-DIP package, and pin assignment are compatible. Electrical performance differences (slew rate, input offset voltage, input bias current) must be evaluated against specific circuit requirements.
