Substitute Part Grouping Explanation
Substitute parts for the LMC660CM are grouped into two categories based on electrical and mechanical compatibility:
Category 1: Direct Texas Instruments Equivalents These parts maintain identical electrical specifications and are packaging variants of the same base product (LMC660). Substitution is based on matching amplifier type (CMOS), circuit count (4), output configuration (push-pull, rail-to-rail), slew rate (1.1 V/µs), gain bandwidth product (1.4 MHz), and supply voltage range (4.75 V to 15.5 V). Package compatibility is maintained at 14-SOIC form factor.
Category 2: Cross-Manufacturer Alternatives These parts are from Analog Devices Inc., Microchip Technology, and STMicroelectronics. Substitution is based on matching the following critical parameters: 4-circuit configuration, rail-to-rail output capability, 14-SOIC package form factor, surface mount mounting type, and supply voltage compatibility within the 5 V to 16 V range. These alternatives may exhibit variations in slew rate, gain bandwidth product, input bias current, and input offset voltage, but remain functionally compatible for applications where the LMC660CM specifications are not exceeded.

Frequently Asked Questions (FAQ)
Q1: Can LMC660CMX/NOPB be used as a direct replacement for LMC660CM?
A: Yes. The LMC660CMX/NOPB is the manufacturer-recommended direct equivalent. Both parts share identical electrical specifications, including amplifier type (CMOS), circuit count (4), output configuration (push-pull, rail-to-rail), slew rate (1.1 V/µs), gain bandwidth product (1.4 MHz), input bias current (0.002 pA), input offset voltage (1 mV), supply current (1.5 mA per 4 channels), output current (40 mA per channel), and supply voltage range (4.75 V to 15.5 V). Package form factor is identical at 14-SOIC. No circuit modifications are required.
Q2: What are the key differences between the LMC660CM and AD8664ARZ?
A: Both parts are 4-circuit CMOS amplifiers in 14-SOIC packages with rail-to-rail output capability. The AD8664ARZ provides enhanced performance: slew rate is 3.5 V/µs (versus 1.1 V/µs), gain bandwidth product is 4 MHz (versus 1.4 MHz), input offset voltage is 50 µV (versus 1 mV), and output current per channel is 140 mA (versus 40 mA). Supply voltage range for AD8664ARZ is 5 V to 16 V, which overlaps the LMC660CM range of 4.75 V to 15.5 V. Operating temperature extends to -40°C to 125°C for the AD8664ARZ. The AD8664ARZ is suitable for applications requiring higher speed and output drive capability.
Q3: Is the TS914IDT suitable for low-voltage applications below 5 V?
A: Yes. The TS914IDT has a minimum supply voltage of 2.7 V, which extends compatibility to lower voltage applications compared to the LMC660CM (4.75 V minimum) and AD8664ARZ (5 V minimum). The TS914IDT maintains CMOS amplifier type, 4-circuit configuration, rail-to-rail output, and 14-SOIC package compatibility. Slew rate (1 V/µs) and gain bandwidth product (1.4 MHz) are closely aligned with the LMC660CM.
Q4: What is the significance of the packaging designations (NOPB, -REEL7, -E/SL)?
A: Packaging designations indicate the physical delivery format and lead finish. NOPB indicates lead-free (no lead) packaging. -REEL7 indicates tape and reel packaging with 7-inch reel diameter. -E/SL indicates tube packaging with lead-free finish. These designations do not affect electrical specifications or functional compatibility. Selection should be based on manufacturing process requirements (tape and reel for automated assembly, tube for manual handling) and procurement volume.
Q5: Can MCP6H04-E/SL replace LMC660CM in all applications?
A: The MCP6H04-E/SL is a general-purpose 4-circuit amplifier with rail-to-rail output in 14-SOIC package, providing functional compatibility. However, electrical specifications differ: slew rate is 0.8 V/µs (versus 1.1 V/µs), gain bandwidth product is 1.2 MHz (versus 1.4 MHz), input bias current is 10 pA (versus 0.002 pA), and input offset voltage is 700 µV (versus 1 mV). Supply current is significantly lower at 135 µA (versus 1.5 mA). The MCP6H04-E/SL is suitable for applications where these specification differences are acceptable and low power consumption is beneficial. Applications requiring the exact electrical performance of the LMC660CM should use LMC660CMX/NOPB or AD8664ARZ.
Q6: What is the operating temperature range difference between LMC660CM and substitute parts?
A: The LMC660CM operates from 0°C to 70°C. Most substitute parts (AD8664ARZ, AD8669ARZ, MCP6H04, TS914IDT) extend the operating temperature range to -40°C to 125°C. The TS914IDT additionally carries AEC-Q100 automotive qualification. For applications requiring operation only within the 0°C to 70°C range, all substitute parts are compatible. For applications requiring extended temperature operation, the AD8664ARZ, AD8669ARZ, MCP6H04, or TS914IDT are appropriate selections.
Q7: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed (LMC660CM/NOPB, LMC660CMX/NOPB, AD8664ARZ, AD8664ARZ-REEL7, AD8669ARZ, AD8669ARZ-REEL7, MCP6H04-E/SL, MCP6H04T-E/SL, TS914IDT) carry RoHS3 compliance status.
