LMP2011MA Equivalent & Substitute Parts
Part Overview
The LMP2011MA is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. This device features rail-to-rail output capability and is designed for low-power applications requiring single-circuit amplification. The LMP2011MA is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute components must maintain functional compatibility across electrical specifications and mechanical packaging to ensure direct replacement capability.

Substitute Part Grouping Explanation
Substitution of the LMP2011MA is determined by strict adherence to the following criteria:
Primary Compatibility Requirements:
- Package / Case: 8-SOIC (0.154", 3.90mm Width) — mandatory for PCB footprint compatibility
- Mounting Type: Surface Mount — required for assembly process compatibility
- Output Type: Rail-to-Rail — functional requirement for signal swing capability
- Number of Circuits: 1 — single amplifier configuration
- Operating Temperature Range: -40°C to 125°C minimum — thermal envelope requirement
- Voltage Supply Span: Minimum 2.7 V to 5.25 V overlap — power supply compatibility
Secondary Electrical Parameters for Functional Equivalence:
- Slew Rate: 4 V/µs or greater — determines signal transition speed capability
- Gain Bandwidth Product: 3 MHz or greater — frequency response requirement
- Current - Supply: 930 µA or lower — power consumption constraint
- Current - Input Bias: 3 pA or lower — input leakage specification
- Voltage - Input Offset: 0.12 µV or lower — DC accuracy requirement
Substitute parts are grouped into two categories based on electrical performance alignment with the LMP2011MA specification envelope.

Compliance and Certification Considerations:
All substitute parts listed are ROHS3 compliant and carry REACH unaffected status. The original LMP2011MA is RoHS non-compliant. All substitute parts maintain MSL 1 (unlimited) moisture sensitivity level. All devices carry EAR99 export classification and HTSUS code 8542.33.0001.
Frequently Asked Questions (FAQ)
Q1: Can the LMP2011MA/NOPB be used as a direct replacement for the LMP2011MA?
A: Yes. The LMP2011MA/NOPB maintains identical electrical specifications and 8-SOIC package configuration. The primary differences are product status (active versus obsolete) and RoHS3 compliance certification. No circuit modifications are required for substitution.
Q2: What is the key difference between the ADA4891-1ARZ variants (standard, -R7, and -RL)?
A: The three ADA4891-1ARZ variants are electrically identical. The differences are packaging formats: ADA4891-1ARZ is supplied in tube, ADA4891-1ARZ-R7 is supplied in cut tape with Digi-Reel, and ADA4891-1ARZ-RL is supplied in tape & reel. Selection depends on assembly equipment compatibility and procurement requirements.
Q3: Is the MAX4289ESA+ suitable for high-frequency applications?
A: No. The MAX4289ESA+ has a gain bandwidth product of only 17 kHz and slew rate of 0.006 V/µs, making it unsuitable for applications requiring bandwidth above 17 kHz. This device is optimized for ultra-low power consumption in DC and very-low-frequency applications.
Q4: What is the operating temperature limitation of the MAX4289ESA+ and MAX4289ESA+T?
A: Both MAX4289 variants are rated for -40°C to 85°C operating temperature, which is 40°C lower than the LMP2011MA specification of -40°C to 125°C. These devices cannot be used in applications requiring operation above 85°C.
Q5: Why do the MCP6V26 devices have lower slew rate and bandwidth than the LMP2011MA?
A: The MCP6V26-E/SN and MCP6V26T-E/SN employ zero-drift amplifier architecture, which inherently trades bandwidth and slew rate for superior DC accuracy. The 2 µV input offset voltage specification is 60× better than the LMP2011MA. These devices are designed for precision DC measurement applications where offset voltage is the critical parameter.
Q6: Are all substitute parts available in 8-SOIC package?
A: Yes. All substitute parts listed are housed in 8-SOIC (0.154", 3.90mm Width) surface-mount package, ensuring PCB footprint compatibility with the LMP2011MA.
Q7: Which substitute part has the highest output current capability?
A: The ADA4891-1ARZ variants provide 125 mA output current per channel, compared to 17 mA for the LMP2011MA. The TS507IDT provides 128 mA output current. Both are suitable for applications requiring higher output drive capability.
Q8: What is the primary advantage of the TS507IDT over the LMP2011MA?
A: The TS507IDT provides 128 mA output current capability (7.5× improvement) and operates across the full -40°C to 125°C temperature range. Supply current is 850 µA, which is lower than the ADA4891 variants but higher than the MAX4289 and MCP6V26 families.
Q9: Can the LMP2011MA be substituted with the MCP6V26-E/SN in a high-speed signal conditioning circuit?
A: No. The MCP6V26-E/SN has a gain bandwidth product of 2 MHz and slew rate of 1 V/µs, both lower than the LMP2011MA. For high-speed applications, the ADA4891-1ARZ variants are more appropriate, offering 240 MHz bandwidth and 210 V/µs slew rate.
Q10: What packaging options are available for the ADA4891-1ARZ?
A: Three packaging options are available: ADA4891-1ARZ (tube), ADA4891-1ARZ-R7 (cut tape with Digi-Reel), and ADA4891-1ARZ-RL (tape & reel). Selection depends on assembly process requirements and procurement volume.
