LMP2011MAX/NOPB Equivalent & Substitute Parts
Part Overview
The LMP2011MAX/NOPB 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, precision analog signal conditioning applications. The part is classified as obsolete, making identification of active equivalent and substitute components essential for ongoing design support and production continuity. Substitute parts must maintain functional compatibility across key electrical parameters including supply voltage range, output type, package configuration, and operating temperature specifications.

Substitute Part Grouping Explanation
Substitution of the LMP2011MAX/NOPB is determined by strict adherence to the following criteria:
Primary Compatibility Requirements:
- Package type: 8-SOIC (0.154", 3.90mm Width)
- Output configuration: Rail-to-Rail
- Number of circuits: 1
- Mounting type: Surface Mount
- Supply voltage range: Minimum 2.7 V, Maximum ≥ 5.25 V
- Operating temperature range: -40°C to 125°C
- RoHS3 compliance and MSL 1 rating
Substitute parts are grouped into two categories:
Category A: Direct Functional Equivalents (Analog Devices ADA4891 Series) These parts maintain identical package, output type, and temperature range specifications. The ADA4891-1ARZ, ADA4891-1ARZ-R7, and ADA4891-1ARZ-RL variants differ only in packaging format (Tube, Cut Tape & Digi-Reel, and Tape & Reel respectively) and are electrically identical. All three are active products with superior performance characteristics.
Category B: Functional Alternatives (Maxim Integrated MAX4289 and Microchip MCP6V26/MCP6V28 Series) These parts meet the core package, output type, and temperature range requirements but operate within different electrical performance envelopes. MAX4289ESA+ and MAX4289ESA+T variants differ in packaging format only. MCP6V26 and MCP6V28 series parts (available in Tube and Tape & Reel formats) are zero-drift amplifiers with different bandwidth and slew rate characteristics.

Engineering Selection Recommendations
For applications requiring direct replacement with identical performance envelope:
The ADA4891-1ARZ series (available in three packaging formats: Tube, Cut Tape & Digi-Reel, and Tape & Reel) represents the primary substitute option. All three variants are electrically identical and maintain active product status with full RoHS3 compliance and MSL 1 rating. Selection among ADA4891-1ARZ, ADA4891-1ARZ-R7, and ADA4891-1ARZ-RL should be based on packaging and supply chain requirements. The ADA4891-1ARZ-R7 variant offers the highest inventory availability (10,250 pcs).
For applications with relaxed upper operating temperature requirements:
The MAX4289ESA+ and MAX4289ESA+T variants are suitable for designs where the maximum operating temperature does not exceed 85°C. Both variants are active products with full compliance certifications. Selection between MAX4289ESA+ (Tube packaging) and MAX4289ESA+T (Tape & Reel packaging) depends on procurement format requirements.
For applications requiring extended temperature operation with zero-drift performance:
The Microchip MCP6V26 and MCP6V28 series (available in both Tube and Tape & Reel formats) maintain the full -40°C to 125°C operating range and offer zero-drift amplifier architecture. MCP6V26-E/SN and MCP6V26T-E/SN are functionally identical, as are MCP6V28-E/SN and MCP6V28T-E/SN, with differences limited to packaging format. All variants are active products with full compliance certifications.
All substitute parts listed maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.
Frequently Asked Questions (FAQ)
Q: Can the ADA4891-1ARZ series be used as a direct drop-in replacement for the LMP2011MAX/NOPB?
A: Yes. The ADA4891-1ARZ, ADA4891-1ARZ-R7, and ADA4891-1ARZ-RL variants are electrically identical and share the same 8-SOIC package footprint, pin configuration, rail-to-rail output type, and operating temperature range (-40°C to 125°C). The three variants differ only in packaging format (Tube, Cut Tape & Digi-Reel, and Tape & Reel respectively). All are active products manufactured by Analog Devices Inc.
Q: What is the difference between MAX4289ESA+ and MAX4289ESA+T?
A: Both variants are electrically identical. The difference is packaging format: MAX4289ESA+ is supplied in Tube packaging, while MAX4289ESA+T is supplied in Tape & Reel (TR) format. Selection depends on procurement and assembly line requirements. Note that the maximum operating temperature for both variants is 85°C, which is lower than the LMP2011MAX/NOPB specification of 125°C.
Q: Are the MCP6V26 and MCP6V28 series interchangeable with each other?
A: The MCP6V26 and MCP6V28 series are both zero-drift amplifiers with identical electrical specifications within each series. MCP6V26-E/SN and MCP6V26T-E/SN are functionally identical (Tube vs. Tape & Reel packaging). Similarly, MCP6V28-E/SN and MCP6V28T-E/SN are functionally identical. However, MCP6V26 and MCP6V28 series differ from each other only in packaging format designation and should be selected based on supply chain availability and procurement requirements.
Q: Do all substitute parts meet RoHS3 compliance and MSL 1 requirements?
A: Yes. All substitute parts listed (ADA4891-1ARZ series, MAX4289ESA series, and MCP6V26/MCP6V28 series) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the LMP2011MAX/NOPB.
Q: What is the key difference between the ADA4891 series and the MCP6V26/MCP6V28 series?
A: The ADA4891 series are general-purpose amplifiers, while the MCP6V26 and MCP6V28 series are zero-drift amplifiers. Zero-drift architecture provides superior input offset voltage stability over temperature and time. The choice between these architectures depends on application requirements for offset voltage performance and drift characteristics.
Q: Can I use MAX4289ESA+ in applications requiring operation above 85°C?
A: No. The MAX4289ESA+ and MAX4289ESA+T variants are specified for operation only to 85°C maximum. For applications requiring the full -40°C to 125°C operating range, use the ADA4891-1ARZ series or the MCP6V26/MCP6V28 series.
Q: What inventory levels are available for each substitute part?
A: Current inventory levels are: ADA4891-1ARZ (1,270 pcs), ADA4891-1ARZ-R7 (10,250 pcs), ADA4891-1ARZ-RL (1,057 pcs), MAX4289ESA+ (1,134 pcs), MAX4289ESA+T (2,320 pcs), MCP6V26-E/SN (3,400 pcs), MCP6V26T-E/SN (743 pcs), MCP6V28-E/SN (3,400 pcs), and MCP6V28T-E/SN (753 pcs).
