LMC662CM Equivalent & Substitute Parts

Part Overview

The LMC662CM is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device features push-pull, rail-to-rail output architecture with a slew rate of 1.1 V/µs and a gain bandwidth product of 1.4 MHz. The part is classified as Active status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the primary LMC662CM becomes unavailable due to inventory constraints, end-of-life status transitions, or when alternative packaging formats are required for manufacturing processes. The LMC662CM/NOPB variant carries Last Time Buy status, making equivalent alternatives critical for long-term design continuity.

Engineering Selection Recommendations

Direct Substitution (Identical Electrical Performance):

LMC662CMX/NOPB is the recommended primary substitute for LMC662CM. This part maintains all electrical specifications while offering Active product status and availability in Cut Tape & Digi-Reel packaging format. With 18,400 units in stock, this variant provides superior supply continuity compared to the original LMC662CM (1,437 units) and the Last Time Buy LMC662CM/NOPB variant (1,994 units).

Cross-Manufacturer Substitution (Enhanced Performance):

AD8662ARZ series (Analog Devices Inc.) provides CMOS dual-channel amplification with enhanced performance metrics: 3.5 V/µs slew rate (versus 1.1 V/µs), 4 MHz gain bandwidth product (versus 1.4 MHz), and extended operating temperature range (−40°C to 125°C versus 0°C to 70°C). The AD8662ARZ-REEL7 variant offers the highest inventory availability (12,200 units) in Cut Tape & Digi-Reel format. This substitution is suitable for applications requiring improved dynamic response and wider temperature operation.

AD8667ARZ series (Analog Devices Inc.) represents a general-purpose amplifier alternative with lower slew rate (0.3 V/µs) and reduced gain bandwidth product (540 kHz). This substitution is applicable only to applications where the LMC662CM's performance specifications exceed design requirements, offering reduced power consumption (230 µA versus 750 µA supply current).

ALD2704SAL (Advanced Linear Devices Inc.) maintains push-pull, rail-to-rail output architecture with CMOS amplifier type. This part exhibits higher slew rate (5 V/µs) and gain bandwidth product (2.1 MHz) but operates within a narrower supply voltage range (6.5 V to 10 V versus 4.75 V to 15.5 V). Substitution is limited to applications operating within this restricted supply span.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status, ensuring regulatory equivalence with the original LMC662CM.

Frequently Asked Questions (FAQ)

Q: Can LMC662CMX/NOPB be used as a direct replacement for LMC662CM?

A: Yes. LMC662CMX/NOPB is electrically identical to LMC662CM. The difference is packaging format: LMC662CMX/NOPB is supplied in Cut Tape & Digi-Reel format, while LMC662CM is supplied in Tube format. Both are 8-SOIC surface mount packages with identical pinout and electrical performance.

Q: What is the difference between LMC662CM/NOPB and LMC662CMX/NOPB?

A: Both parts are electrically identical. The primary difference is product status: LMC662CM/NOPB is Last Time Buy status, indicating limited future availability, while LMC662CMX/NOPB is Active status with higher inventory (18,400 units versus 1,994 units). For new designs or long-term production, LMC662CMX/NOPB is the preferred choice.

Q: Can AD8662ARZ replace LMC662CM in all applications?

A: AD8662ARZ meets the primary substitution criteria (CMOS, dual-channel, rail-to-rail, 8-SOIC package) and exceeds performance specifications in slew rate and gain bandwidth product. However, it operates at a higher supply current (1.25 mA versus 750 µA) and requires a minimum supply voltage of 5 V (versus 4.75 V). Applications operating below 5 V or with strict power budgets may not be suitable for this substitution.

Q: Is AD8667ARZ a suitable substitute for LMC662CM?

A: AD8667ARZ is not recommended as a direct substitute. While it shares the 8-SOIC package and rail-to-rail output, it is classified as a general-purpose amplifier rather than CMOS type, and exhibits significantly lower slew rate (0.3 V/µs versus 1.1 V/µs) and gain bandwidth product (540 kHz versus 1.4 MHz). This substitution is only appropriate for applications where the LMC662CM's performance specifications exceed design requirements.

Q: What is the operating temperature range difference between LMC662CM and AD8662ARZ?

A: LMC662CM operates from 0°C to 70°C, while AD8662ARZ operates from −40°C to 125°C. If your application requires operation below 0°C or above 70°C, AD8662ARZ provides extended temperature capability. Conversely, if your application operates only within 0°C to 70°C, both parts are functionally equivalent in this regard.

Q: Can ALD2704SAL be used in applications requiring supply voltages below 6.5 V?

A: No. ALD2704SAL has a minimum supply voltage specification of 6.5 V, while LMC662CM operates down to 4.75 V. Applications requiring operation at supply voltages between 4.75 V and 6.5 V cannot use ALD2704SAL as a substitute.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (LMC662CMX/NOPB, AD8662ARZ series, AD8667ARZ series, and ALD2704SAL) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original LMC662CM.

Q: What packaging formats are available for LMC662CM equivalents?

A: LMC662CM is available in Tube packaging. LMC662CM/NOPB is also available in Tube format. LMC662CMX/NOPB is available in Cut Tape & Digi-Reel format. All AD8662ARZ and AD8667ARZ variants are available in either Tube or Cut Tape & Digi-Reel formats. ALD2704SAL is available in Tube format. Select the packaging format compatible with your manufacturing process.
