LMC6035IMM Equivalent & Substitute Parts

Part Overview

The LMC6035IMM is a CMOS dual-channel differential, rail-to-rail amplifier manufactured by Texas Instruments in an 8-VSSOP surface mount package. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement continuity. The LMC6035IMM operates across a wide supply voltage range of 2V to 15.5V and is suitable for low-power analog signal conditioning applications requiring rail-to-rail output capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMC6035IMM is determined by the following critical parameters: amplifier type (CMOS), number of circuits (2), output type (rail-to-rail capability), supply voltage range compatibility, package form factor (8-pin surface mount), and operating temperature range. Substitute parts must maintain functional equivalence in these core electrical and mechanical characteristics.

The substitute parts are grouped into two categories:

Category 1: Direct Equivalent (Same Base Product) LMC6035IMM/NOPB is the direct equivalent of LMC6035IMM, differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete). All electrical parameters are identical.

Category 2: Functional Substitutes (Alternative Manufacturers) AD8662ARMZ, AD8662ARMZ-REEL, AD8667ARMZ, and AD8667ARMZ-REEL are functional substitutes from Analog Devices Inc. These devices maintain the dual-circuit, rail-to-rail, 8-pin surface mount configuration and operate within compatible supply voltage ranges. However, they exhibit different electrical performance characteristics in slew rate, gain bandwidth product, input offset voltage, and supply current specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): LMC6035IMM/NOPB is the recommended direct substitute. This part maintains all electrical specifications of the original LMC6035IMM while offering active product status and ROHS3 compliance. The only difference is packaging format (Tape & Reel). This substitution requires no circuit redesign or validation.

For Functional Substitution (Performance Trade-offs):

AD8662ARMZ and AD8662ARMZ-REEL are suitable when higher slew rate (3.5V/µs versus 1.5V/µs) and greater gain bandwidth product (4 MHz versus 1.4 MHz) are acceptable or beneficial. These devices offer improved output current capability (140 mA versus 8 mA per channel) but require minimum supply voltage of 5V (versus 2V for LMC6035IMM). Both are ROHS3 compliant and active products with extended operating temperature range (-40°C to 125°C).

AD8667ARMZ and AD8667ARMZ-REEL are suitable for applications where lower supply current (230 µA versus 650 µA) is critical and lower slew rate (0.3V/µs) is acceptable. These general-purpose amplifiers offer superior input offset voltage (40 µV versus 500 µV) and lower output current per channel (50 mA versus 8 mA). Minimum supply voltage requirement is 5V. Both are ROHS3 compliant and active products.

All Analog Devices substitutes require verification that the minimum 5V supply voltage requirement is compatible with the application circuit design.

Frequently Asked Questions (FAQ)

Q: Can LMC6035IMM/NOPB be used as a direct replacement for LMC6035IMM? A: Yes. LMC6035IMM/NOPB is electrically and functionally identical to LMC6035IMM. The difference is packaging format (Tape & Reel versus bulk). No circuit modification is required. LMC6035IMM/NOPB is an active product with ROHS3 compliance.

Q: What is the primary limitation when substituting with AD8662ARMZ or AD8667ARMZ? A: The minimum supply voltage increases from 2V to 5V. Applications operating at supply voltages below 5V cannot use these Analog Devices substitutes without circuit redesign.

Q: How do AD8662ARMZ and AD8667ARMZ differ in performance? A: AD8662ARMZ is optimized for higher speed applications with 3.5V/µs slew rate and 4 MHz gain bandwidth product, plus higher output current (140 mA per channel). AD8667ARMZ is optimized for low-power applications with 230 µA supply current and lower slew rate (0.3V/µs). Both maintain rail-to-rail output and dual-circuit configuration.

Q: Are the package dimensions identical across all substitute parts? A: Yes. All parts use 8-pin surface mount packages (8-TSSOP, 8-MSOP) with 0.118" width and 3.00mm height. PCB layout and footprints are compatible.

Q: What is the difference between AD8662ARMZ and AD8662ARMZ-REEL? A: Both are electrically identical. AD8662ARMZ is supplied in Tube packaging; AD8662ARMZ-REEL is supplied in Cut Tape and Digi-Reel packaging. Selection depends on procurement and assembly requirements.

Q: Are all substitute parts RoHS compliant? A: LMC6035IMM is RoHS non-compliant. LMC6035IMM/NOPB and all Analog Devices substitutes (AD8662ARMZ, AD8662ARMZ-REEL, AD8667ARMZ, AD8667ARMZ-REEL) are ROHS3 compliant.

Q: What is the operating temperature range difference? A: LMC6035IMM and LMC6035IMM/NOPB operate from -40°C to 85°C. All Analog Devices substitutes operate from -40°C to 125°C, providing extended high-temperature capability.

Q: Can I use AD8667ARMZ in a high-speed signal conditioning application? A: AD8667ARMZ has a slew rate of 0.3V/µs and gain bandwidth product of 540 kHz, which is lower than LMC6035IMM (1.5V/µs and 1.4 MHz). It is suitable for low-frequency, low-power applications but not for high-speed signal conditioning.
