Engineering Selection Recommendations
For Direct Replacement (Identical Specifications):
LMC662AIMX/NOPB is the primary recommended substitute. This Texas Instruments part maintains identical electrical specifications to the LMC662AIM while offering Active product status, ensuring long-term availability. The part is available in Cut Tape & Digi-Reel® packaging with 42,600 units in stock. ROHS3 compliance and MSL 1 rating match the original specification.
LMC662AIM/NOPB provides an alternative direct equivalent from National Semiconductor with identical electrical parameters and Active status, though with lower inventory (1,653 units).
For Enhanced Performance Applications:
TLC2272 series devices (CDR, ID, IDR, MDR variants) offer improved performance metrics while maintaining 8-SOIC packaging and CMOS technology. These parts feature 3.6 V/µs slew rate and 2.25 MHz gain bandwidth product, representing a 3.3× improvement in bandwidth. Supply voltage range (4.4 V to 16 V) overlaps the LMC662AIM specification. All variants are ROHS3 compliant with MSL 1 rating and Active product status. Selection among variants depends on packaging requirements (Tube, Cut Tape, or Tape & Reel) and temperature range needs.
TLC2272MDR supports the widest temperature range (-55°C to 125°C) and is recommended for extended-temperature applications.
For Maximum Performance and Low-Power Operation:
AD8662ARZ series devices provide superior electrical performance: 4 MHz gain bandwidth product, 3.5 V/µs slew rate, and 50 µV input offset voltage. Output current capability reaches 140 mA per channel. These parts are ROHS3 compliant, MSL 1 rated, and Active status. Minimum supply voltage is 5 V (vs. 4.75 V for LMC662AIM), which may require circuit evaluation in low-voltage applications. Packaging variants (Tube, Tape & Reel) are available with substantial inventory.
For Low-Bandwidth, Low-Power Applications:

Both devices feature identical slew rate (1.1 V/µs), gain bandwidth product (1.4 MHz), input offset voltage (1 mV), supply current (750 µA per channel), and output current (40 mA per channel). The 8-SOIC package dimensions are identical. The primary difference is product status: LMC662AIMX/NOPB is Active, while LMC662AIM is Last Time Buy.
Q: What is the difference between LMC662AIM/NOPB and LMC662AIMX/NOPB?
A: Both parts are electrically identical with identical electrical specifications. The difference is manufacturer designation and packaging format. LMC662AIM/NOPB is from National Semiconductor with Bulk packaging, while LMC662AIMX/NOPB is from Texas Instruments with Cut Tape & Digi-Reel® packaging. LMC662AIMX/NOPB has significantly higher inventory availability (42,600 units vs. 1,653 units).
Q: Can TLC2272 series devices replace LMC662AIM in all applications?
A: TLC2272 devices are pin-compatible and functionally compatible in most applications. However, electrical performance differs: TLC2272 offers higher slew rate (3.6 V/µs vs. 1.1 V/µs) and higher gain bandwidth product (2.25 MHz vs. 1.4 MHz). These improvements are generally beneficial but may require circuit re-evaluation in applications with tight bandwidth specifications or noise-sensitive designs. The minimum supply voltage is 4.4 V (vs. 4.75 V), which is acceptable. Operating temperature range varies by variant; TLC2272CDR operates 0°C to 70°C, while TLC2272ID, IDR, and MDR support -40°C to 125°C.
Q: What are the key differences between AD8662 and LMC662AIM?
A: AD8662 devices provide significantly enhanced performance: 4 MHz gain bandwidth product (vs. 1.4 MHz), 3.5 V/µs slew rate (vs. 1.1 V/µs), 50 µV input offset voltage (vs. 1 mV), and 140 mA output current per channel (vs. 40 mA). Supply current is lower (625 µA per channel vs. 750 µA). The minimum supply voltage is 5 V (vs. 4.75 V), which may impact low-voltage applications. All AD8662 variants are ROHS3 compliant and Active status.
Q: Is AD8667ARZ suitable as a replacement for LMC662AIM?
A: AD8667ARZ is not recommended as a direct replacement. While both are dual-channel CMOS amplifiers in 8-SOIC packages, AD8667ARZ is classified as a general-purpose amplifier with significantly lower bandwidth (540 kHz vs. 1.4 MHz) and slew rate (0.3 V/µs vs. 1.1 V/µs). This part is suitable only for low-speed applications where the LMC662AIM's performance specifications are not required.
Q: What packaging options are available for substitute parts?
A: Substitute parts are available in multiple packaging formats: Bulk, Tube, Cut Tape & Digi-Reel®, and Tape & Reel (TR). LMC662AIMX/NOPB is available in Cut Tape & Digi-Reel® format with highest inventory. TLC2272 variants are available in all formats depending on part number suffix. AD8662 variants are available in Tube, Tape & Reel, and Cut Tape & Digi-Reel® formats. Selection depends on manufacturing process requirements and volume needs.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All recommended substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original LMC662AIM specification.
Q: What is the temperature range consideration when selecting a substitute?
A: LMC662AIM operates -40°C to 85°C. TLC2272CDR operates 0°C to 70°C (narrower range), while TLC2272ID, IDR, and MDR support -40°C to 125°C (extended range). AD8662 and AD8667 variants support -40°C to 125°C. For applications requiring the original -40°C to 85°C range, TLC2272ID, IDR, MDR, or AD8662 variants are appropriate. TLC2272CDR is not suitable for below 0°C operation.
