LMC6036IM Equivalent & Substitute Parts

Part Overview

The LMC6036IM is a CMOS quad operational amplifier manufactured by Texas Instruments, designed for low-power applications requiring rail-to-rail output capability. This device integrates four independent differential amplifier circuits in a 14-SOIC surface mount package. The LMC6036IM is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and production continuity. Substitute parts must maintain electrical compatibility across supply voltage ranges, output characteristics, and thermal operating conditions while accommodating modern component availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMC6036IM is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Amplifier Type: CMOS architecture
• Number of Circuits: Four independent amplifier channels
• Output Type: Rail-to-rail capability with differential output configuration
• Package / Case: 14-SOIC form factor (0.154", 3.90mm Width)
• Mounting Type: Surface mount technology

Secondary Compatibility Parameters:

• Gain Bandwidth Product: 1.4 MHz (exact match required)
• Voltage - Supply Span: Minimum 2V to maximum 15.5V operating range
• Operating Temperature: Minimum -40°C to maximum 85°C
• Current - Input Bias: 0.02 pA specification
• Voltage - Input Offset: 500 µV specification

Substitute parts must satisfy all primary criteria and maintain electrical performance within the secondary parameter specifications to ensure functional equivalence in existing circuit designs.

Engineering Selection Recommendations

LMC6036IM/NOPB (Direct Manufacturer Equivalent): This part represents the direct successor designation from National Semiconductor and maintains identical electrical specifications to the original LMC6036IM. Product status is active, ensuring continued availability. AEC-Q100 automotive qualification is included. This option is recommended for applications requiring exact parameter matching and where the original design specifications must be preserved without modification.

TS914AIDT (STMicroelectronics Alternative): The TS914AIDT provides functional substitution with the following considerations: slew rate is reduced to 1.0 V/µs (versus 1.5 V/µs), input bias current is increased to 1 pA (versus 0.02 pA), and input offset voltage is increased to 5 mV (versus 500 µV). Supply voltage minimum is raised to 2.7 V (versus 2 V). Conversely, output current per channel is increased to 60 mA (versus 8 mA), and supply current is reduced to 230 µA (versus 1.3 mA). Operating temperature range extends to 125°C. This part is ROHS3 compliant and AEC-Q100 qualified. Selection of this alternative requires circuit-level verification that the modified electrical characteristics remain compatible with application requirements.

Frequently Asked Questions (FAQ)

Q: Can the TS914AIDT directly replace the LMC6036IM without circuit modification?

A: The TS914AIDT shares the same 14-SOIC package and quad CMOS amplifier architecture. However, electrical parameter differences exist. The reduced slew rate (1.0 versus 1.5 V/µs), increased input offset voltage (5 mV versus 500 µV), and higher minimum supply voltage (2.7 V versus 2 V) may affect circuit performance depending on application requirements. Pin-for-pin compatibility exists, but functional equivalence requires verification against specific circuit design constraints.

Q: What is the primary advantage of LMC6036IM/NOPB over the original LMC6036IM?

A: The LMC6036IM/NOPB maintains identical electrical specifications while offering active product status and AEC-Q100 automotive qualification. This designation represents the current production equivalent and is recommended for new designs and production continuity where exact parameter matching is required.

Q: Are all substitute parts available in the same packaging format?

A: Yes. Both LMC6036IM/NOPB and TS914AIDT are supplied in 14-SOIC (0.154", 3.90mm Width) surface mount packages, matching the original LMC6036IM package specification. Mounting type and PCB footprint compatibility are maintained across all three parts.

Q: What compliance differences exist between the substitute parts?

A: The LMC6036IM is RoHS non-compliant. The LMC6036IM/NOPB compliance status is not specified in available documentation. The TS914AIDT is ROHS3 compliant. Both LMC6036IM/NOPB and TS914AIDT carry AEC-Q100 automotive qualification, whereas the original LMC6036IM does not specify this certification.

Q: Which substitute part is recommended for low-power applications?

A: The TS914AIDT offers significantly lower supply current (230 µA total versus 1.3 mA for the LMC6036IM). For applications where power consumption is a primary design constraint, the TS914AIDT provides superior efficiency. However, the trade-off includes reduced slew rate and increased input offset voltage.

Q: Is the 14-SOIC package pinout identical across all three parts?

A: All three parts utilize the 14-SOIC package format with 0.154" (3.90mm) width. Pin-for-pin compatibility is maintained, allowing direct PCB footprint reuse. Functional verification of electrical characteristics remains necessary based on application-specific requirements.
