Substitute Part Grouping Explanation

Substitution of the LPC662AIMX is determined by strict equivalence across the following critical parameters:

• Amplifier Type: CMOS technology
• Circuit Count: Dual-channel configuration (2 circuits)
• Output Configuration: Push-pull, rail-to-rail topology
• Electrical Performance: Slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current specifications
• Supply Voltage Range: 4.75 V to 15.5 V operation
• Temperature Range: -40°C to 85°C junction temperature
• Package Format: 8-SOIC surface mount package with 3.90mm width

The LPC662AIMX/NOPB represents a direct manufacturer equivalent with identical electrical specifications and package configuration. Substitution is valid only when all parameters listed above match the original component specification.

Parameter Comparison

Engineering Selection Recommendations

The LPC662AIMX is classified as obsolete. The LPC662AIMX/NOPB is designated as Last Time Buy status, indicating limited future availability. Both components are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications.

The primary distinction between these parts is regulatory compliance. The LPC662AIMX/NOPB achieves ROHS3 compliance, whereas the original LPC662AIMX is RoHS non-compliant. Both components are REACH Unaffected and carry EAR99 export classification.

For new designs and ongoing procurement, the LPC662AIMX/NOPB is the appropriate selection due to its RoHS3 compliance status and Last Time Buy designation, which provides extended availability compared to the obsolete LPC662AIMX. Electrical performance and package compatibility are fully equivalent between these components.

Frequently Asked Questions (FAQ)

Q: Can the LPC662AIMX/NOPB be used as a direct replacement for the LPC662AIMX?

A: Yes. The LPC662AIMX/NOPB is electrically and mechanically equivalent to the LPC662AIMX. All electrical parameters, including slew rate, gain bandwidth product, input bias current, supply voltage range, and output current specifications are identical. Both components use the 8-SOIC surface mount package with 3.90mm width. Pin configuration and functional operation are identical.

Q: What is the difference between LPC662AIMX and LPC662AIMX/NOPB?

A: The primary difference is packaging designation and regulatory compliance. The LPC662AIMX/NOPB is supplied in Cut Tape (CT) and Digi-Reel® packaging formats and achieves ROHS3 compliance. The LPC662AIMX is RoHS non-compliant. Electrical specifications and performance characteristics are identical.

Q: Why is the LPC662AIMX marked as obsolete?

A: The LPC662AIMX has reached end-of-life status with Texas Instruments. The LPC662AIMX/NOPB is designated Last Time Buy, indicating that inventory is limited and future production is not planned. For continued design support, the LPC662AIMX/NOPB should be specified.

Q: Are there any pin configuration differences between these parts?

A: No. Both the LPC662AIMX and LPC662AIMX/NOPB use the 8-SOIC package with identical pin assignments and functional configuration. No PCB layout modifications are required for substitution.

Q: What supply voltage range does the LPC662AIMX support?

A: The LPC662AIMX operates across a supply voltage range of 4.75 V to 15.5 V. This wide range accommodates both single and dual supply configurations in typical amplifier applications.

Q: What is the output current capability per channel?

A: The LPC662AIMX delivers 40 mA output current per channel. With two independent circuits, total output current capability is 80 mA across both channels.

Q: Is the LPC662AIMX suitable for low-power applications?

A: Yes. The LPC662AIMX exhibits low supply current of 86 µA per dual-channel configuration and extremely low input bias current of 0.002 pA, making it suitable for battery-powered and low-power circuit designs.
