LMC6064AIM Equivalent & Substitute Parts

Part Overview

The LMC6064AIM is a CMOS rail-to-rail operational amplifier manufactured by Texas Instruments, configured as a 4-circuit integrated circuit in 14-SOIC surface mount packaging. This device is classified as "Not For New Designs," indicating it has reached end-of-life status. The LMC6064AIM operates across a wide supply voltage range of 4.5V to 15.5V and is suitable for low-power applications requiring ultra-low input bias current and minimal input offset voltage. Due to its discontinued design status and non-RoHS3 compliance, identification of functionally equivalent substitute components is necessary for ongoing production support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the LMC6064AIM is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Compatibility Parameters:

Package / Case: 14-SOIC (0.154", 3.90mm Width) — pin-for-pin compatibility required
Mounting Type: Surface Mount
Number of Circuits: 4
Output Type: Rail-to-Rail
Voltage - Supply Span: minimum 4.5V, maximum 15.5V (substitute must support this range)

Functional Parameters:

Amplifier Type: CMOS or General Purpose (both acceptable for functional equivalence)
Operating Temperature: -40°C to 85°C minimum (substitute may exceed this range)

Substitute parts are grouped into two categories:

Category 1: Direct Packaging Equivalents (Same Packaging)

LMC6064AIM/NOPB (Texas Instruments, Tube packaging, RoHS3 Compliant, Last Time Buy status)

Category 2: Enhanced Performance Alternatives (Analog Devices, Active Status)

AD8664ARZ and AD8664ARZ-REEL7 (CMOS type, higher performance specifications)
AD8669ARZ, AD8669ARZ-REEL, and AD8669ARZ-REEL7 (General Purpose type, moderate performance)

All substitute parts maintain 14-SOIC packaging, surface mount configuration, and 4-circuit architecture. Electrical performance characteristics vary; substitutes from Analog Devices provide enhanced specifications including higher slew rates, increased gain bandwidth products, and improved temperature operating ranges.

Engineering Selection Recommendations

For Direct Replacement (Existing Designs):

The LMC6064AIM/NOPB is the primary direct substitute. It maintains identical electrical specifications and 14-SOIC packaging, ensuring pin-for-pin compatibility. The LMC6064AIM/NOPB carries RoHS3 compliance and Last Time Buy status, making it suitable for production continuation of existing designs. This part is recommended when design modification is not feasible and electrical performance requirements remain unchanged.

For New Designs and Enhanced Performance:

The AD8664ARZ and AD8664ARZ-REEL7 (Analog Devices, CMOS type) are recommended for new designs requiring improved performance. These parts offer 100× higher slew rate (3.5V/µs vs. 0.035V/µs), 40× higher gain bandwidth product (4 MHz vs. 100 kHz), and extended operating temperature range (-40°C to 125°C). Both maintain 14-SOIC packaging and 4-circuit configuration. The AD8664ARZ-REEL7 variant is packaged in Tape & Reel format, suitable for automated assembly. Both parts carry Active product status and RoHS3 compliance.

For Moderate Performance Requirements:

The AD8669ARZ, AD8669ARZ-REEL, and AD8669ARZ-REEL7 (Analog Devices, General Purpose type) provide intermediate performance characteristics. These parts offer 5.4× higher gain bandwidth product (540 kHz vs. 100 kHz) and improved input offset voltage (40 µV vs. 100 µV) compared to the LMC6064AIM. Supply current is higher (230 µA vs. 80 µA per channel), but output current capability is doubled (50 mA vs. 26 mA per channel). All three variants maintain 14-SOIC packaging, Active product status, and RoHS3 compliance. The REEL and REEL7 variants are packaged in Tape & Reel format.

Compliance Considerations:

All substitute parts from Analog Devices carry RoHS3 compliance, addressing the non-compliant status of the original LMC6064AIM. The LMC6064AIM/NOPB also achieves RoHS3 compliance. All parts maintain REACH Unaffected and EAR99 ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the AD8664ARZ directly replace the LMC6064AIM in existing circuit designs?

A: Pin-for-pin replacement is possible due to identical 14-SOIC packaging and 4-circuit configuration. However, electrical performance differs significantly. The AD8664ARZ exhibits 100× higher slew rate and 40× higher gain bandwidth product. Circuit behavior may change in applications sensitive to frequency response or transient response characteristics. Functional verification is required before production implementation.

Q: What is the key difference between AD8664ARZ and AD8669ARZ?

A: Both are Analog Devices 4-circuit rail-to-rail amplifiers in 14-SOIC packaging. The AD8664ARZ is CMOS type with 4 MHz gain bandwidth product and 3.5V/µs slew rate. The AD8669ARZ is General Purpose type with 540 kHz gain bandwidth product and 0.3V/µs slew rate. The AD8664ARZ provides higher speed performance; the AD8669ARZ provides lower power consumption (230 µA vs. 1.25 mA per channel).

Q: Is the LMC6064AIM/NOPB suitable for new designs?

A: The LMC6064AIM/NOPB carries Last Time Buy status, indicating limited future availability. It is not recommended for new designs. For new designs, Analog Devices AD8664ARZ or AD8669ARZ variants are preferred due to Active product status and extended lifecycle support.

Q: What packaging options are available for substitute parts?

A: Tube packaging is available for LMC6064AIM/NOPB, AD8664ARZ, and AD8669ARZ. Tape & Reel (TR) packaging is available for AD8664ARZ-REEL7, AD8669ARZ-REEL, and AD8669ARZ-REEL7. Tape & Reel variants are optimized for automated assembly processes.

Q: Does the minimum supply voltage differ between the LMC6064AIM and Analog Devices substitutes?

A: Yes. The LMC6064AIM operates from 4.5V minimum; Analog Devices substitutes (AD8664ARZ and AD8669ARZ series) operate from 5V minimum. Designs operating below 5V require the LMC6064AIM or LMC6064AIM/NOPB. For 5V and higher supply voltages, all parts are compatible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The LMC6064AIM/NOPB and all Analog Devices substitute parts (AD8664ARZ, AD8664ARZ-REEL7, AD8669ARZ, AD8669ARZ-REEL, AD8669ARZ-REEL7) carry RoHS3 compliance. The original LMC6064AIM is RoHS non-compliant.

Q: What is the inventory status of substitute parts?

A: LMC6064AIM/NOPB: 641 pcs. AD8664ARZ: 2100 pcs. AD8664ARZ-REEL7: 918 pcs. AD8669ARZ: 3820 pcs. AD8669ARZ-REEL: 1144 pcs. AD8669ARZ-REEL7: 794 pcs. Inventory levels reflect current stock availability.
