Key Parameters

Substitute Part Grouping Explanation

Substitution of the LPC662AIM/NOPB is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Matching Criteria:

• Amplifier Type: CMOS
• Number of Circuits: 2 channels
• Output Type: Push-Pull, Rail-to-Rail
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Voltage Supply Range: Minimum 4.75 V to Maximum 15.5 V (or compatible subset)
• Operating Temperature Range: -40°C to 85°C (TJ)
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Performance Parameters (Non-Limiting for Substitution): Performance characteristics such as slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current per channel may vary between substitute parts. These parameters do not restrict substitution eligibility but should be evaluated for specific application requirements.

The LMC6082AIMX/NOPB meets all mandatory matching criteria and is identified as the manufacturer-recommended substitute.

Engineering Selection Recommendations

LPC662AIM/NOPB Status: The LPC662AIM/NOPB is designated Last Time Buy, indicating that Texas Instruments has discontinued production. Current inventory of 1621 pieces is available; however, future procurement will not be possible once existing stock is exhausted.

LMC6082AIMX/NOPB Recommendation: The LMC6082AIMX/NOPB is the manufacturer-recommended substitute and carries Active product status, ensuring long-term availability and continued manufacturing support. This part is fully compatible at the package, pinout, and functional level. The LMC6082AIMX/NOPB is available in higher inventory (2700 pieces) and is supplied in Cut Tape (CT) and Digi-Reel® packaging formats.

Compliance Alignment: Both parts maintain identical RoHS3 compliance, MSL rating of 1 (Unlimited), REACH unaffected status, and ECCN/HTSUS classifications. No regulatory or environmental compliance barriers exist for substitution.

Supply Chain Continuity: For applications currently using the LPC662AIM/NOPB, transition to the LMC6082AIMX/NOPB is recommended to ensure uninterrupted component availability and eliminate future supply chain risk.

Frequently Asked Questions (FAQ)

Q: Are the LPC662AIM/NOPB and LMC6082AIMX/NOPB pin-compatible?

A: Both devices are housed in 8-SOIC packages with identical physical dimensions (0.154", 3.90mm width). Pin compatibility is confirmed for dual-channel CMOS amplifier applications with push-pull, rail-to-rail output configuration.

Q: What is the difference in performance between these two parts?

A: The LMC6082AIMX/NOPB exhibits superior performance characteristics: slew rate of 1.5 V/µs versus 0.11 V/µs, gain bandwidth product of 1.3 MHz versus 350 kHz, and lower input offset voltage of 150 µV versus 1 mV. These improvements do not restrict substitution but may enhance circuit performance in bandwidth-sensitive applications.

Q: Can I use the LMC6082AIMX/NOPB as a direct replacement in existing PCB designs?

A: Yes. The LMC6082AIMX/NOPB is a direct functional and mechanical replacement. No PCB layout modifications are required. Both parts operate within the same voltage supply range (-40°C to 85°C operating temperature) and maintain identical RoHS3 and MSL compliance.

Q: Why is the LPC662AIM/NOPB designated Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued this product line. Existing inventory is available for final orders, but no future production is planned. The LMC6082AIMX/NOPB represents the active successor product.

Q: What packaging options are available for the substitute part?

A: The LMC6082AIMX/NOPB is supplied in Cut Tape (CT) and Digi-Reel® packaging, offering flexibility for both manual assembly and automated production environments.

Q: Are there any supply voltage considerations when substituting?

A: The LMC6082AIMX/NOPB supports a minimum supply voltage of 4.5 V, compared to 4.75 V for the LPC662AIM/NOPB. Both support maximum supply voltage of 15.5 V. Applications operating at supply voltages between 4.5 V and 4.75 V will benefit from the expanded lower voltage range of the substitute part.
