Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMC6484IN is determined by strict equivalence across the following critical parameters:

Electrical Characteristics:

• Amplifier Type: CMOS
• Number of Circuits: 4
• Output Type: Rail-to-Rail
• Slew Rate: 1.3 V/µs
• Gain Bandwidth Product: 1.5 MHz
• Current - Input Bias: 0.02 pA
• Voltage - Input Offset: 110 µV
• Current - Supply: 2.6 mA (x4 Channels)
• Current - Output / Channel: 30 mA
• Voltage - Supply Span: 3 V to 15.5 V
• Operating Temperature Range: -40°C to 85°C (TJ)

Mechanical Characteristics:

• Mounting Type: Through Hole

Substitute parts must match all electrical and mechanical parameters without deviation. Packaging format variations (such as tube versus bulk) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

LMC6484IN/NOPB is the direct functional equivalent of LMC6484IN. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and regulatory compliance:

• LMC6484IN carries obsolete status with RoHS non-compliant classification
• LMC6484IN/NOPB carries active product status with ROHS3 compliance

For new designs or systems requiring regulatory compliance with modern environmental standards, LMC6484IN/NOPB is the appropriate selection. For legacy system maintenance where existing inventory of LMC6484IN is available, direct substitution with LMC6484IN/NOPB is electrically and mechanically valid.

Both parts are supplied in 14-PDIP packaging. The packaging format difference (tube versus bulk) does not affect circuit performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can LMC6484IN/NOPB replace LMC6484IN in existing designs?

A: Yes. LMC6484IN/NOPB is electrically and mechanically equivalent to LMC6484IN. All electrical parameters, pin configuration, and package dimensions are identical. Direct substitution on PCBs designed for 14-DIP through-hole mounting is valid.

Q: What is the difference between LMC6484IN and LMC6484IN/NOPB?

A: The primary differences are product status and RoHS compliance. LMC6484IN is obsolete and RoHS non-compliant. LMC6484IN/NOPB is active and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use 14-DIP (0.300", 7.62mm) package format for through-hole mounting. The supplier device package designation is 14-PDIP for both. Packaging format variations (tube versus bulk) do not affect functional equivalence or board integration.

Q: What supply voltage range is supported by these amplifiers?

A: Both LMC6484IN and LMC6484IN/NOPB operate across a supply voltage span of 3 V to 15.5 V, enabling use in single-supply and dual-supply configurations.

Q: What is the output current capability per channel?

A: Each of the four amplifier circuits in both LMC6484IN and LMC6484IN/NOPB provides 30 mA output current per channel.

Q: Are these CMOS amplifiers suitable for low-power applications?

A: Yes. Both parts feature CMOS technology with input bias current of 0.02 pA and total supply current of 2.6 mA across four channels, making them suitable for low-power analog signal processing.
