LMP2011MAX Equivalent & Substitute Parts

Part Overview

The LMP2011MAX 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 analog signal processing applications. The LMP2011MAX is classified as obsolete, necessitating identification of active substitute components that maintain functional and mechanical compatibility. Substitute parts must satisfy the same electrical performance envelope and physical packaging requirements to ensure direct replacement capability in existing designs.

Engineering Selection Recommendations

ADA4891-1ARZ, ADA4891-1ARZ-R7, ADA4891-1ARZ-RL

These Analog Devices components are active products with ROHS3 compliance. All three variants share identical electrical specifications and differ only in packaging format (Tube, Cut Tape & Digi-Reel®, and Tape & Reel respectively). The ADA4891-1ARZ-RL variant maintains the same Tape & Reel packaging as the original LMP2011MAX. These parts provide superior performance characteristics including 210 V/µs slew rate and 240 MHz bandwidth, with extended operating temperature range to 125°C. Selection among these three variants depends on procurement and assembly requirements.

MAX4289ESA+ and MAX4289ESA+T

These Analog Devices/Maxim Integrated components are active products with ROHS3 compliance. The MAX4289ESA+T variant maintains Tape & Reel packaging consistent with the LMP2011MAX. These parts operate within a reduced temperature range (-40°C to 85°C) and exhibit significantly lower bandwidth (17 kHz) and slew rate (0.006 V/µs). Selection is appropriate for applications with relaxed bandwidth requirements and where ultra-low power consumption (18 µA) is prioritized.

TS507IDT

This STMicroelectronics component is an active product with ROHS3 compliance and Tape & Reel packaging. It provides intermediate performance characteristics with 0.6 V/µs slew rate and 1.9 MHz bandwidth, operating across the full -40°C to 125°C temperature range. This part is suitable for applications requiring performance between the MAX4289 and ADA4891 series.

All substitute parts maintain mechanical compatibility through identical 8-SOIC packaging and surface mount mounting type. All substitute parts are active products with current manufacturing status and regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the ADA4891-1ARZ directly replace the LMP2011MAX in existing PCB designs?

A: Yes. The ADA4891-1ARZ maintains identical 8-SOIC package dimensions (0.154", 3.90mm width) and pinout compatibility. No PCB modifications are required for mechanical placement. Electrical performance is enhanced across all measured parameters.

Q: What is the primary difference between ADA4891-1ARZ, ADA4891-1ARZ-R7, and ADA4891-1ARZ-RL?

A: These three part numbers are electrically identical. The differences are in packaging format: ADA4891-1ARZ is supplied in Tube packaging, ADA4891-1ARZ-R7 in Cut Tape & Digi-Reel® format, and ADA4891-1ARZ-RL in Tape & Reel format. Selection depends on assembly line requirements and procurement preferences.

Q: Why do the MAX4289ESA+ and MAX4289ESA+T have lower bandwidth than the LMP2011MAX?

A: The MAX4289 series is designed for ultra-low power consumption applications (18 µA supply current versus 930 µA for the LMP2011MAX). This design trade-off results in reduced bandwidth (17 kHz) and slew rate (0.006 V/µs). These parts are suitable only for applications where bandwidth requirements are below 17 kHz.

Q: Is the TS507IDT suitable as a direct replacement?

A: The TS507IDT provides mechanical compatibility and operates across the full -40°C to 125°C temperature range. However, its bandwidth (1.9 MHz) and slew rate (0.6 V/µs) are lower than the LMP2011MAX. It is suitable for applications where these performance levels are acceptable.

Q: What is the significance of the RoHS compliance difference?

A: The LMP2011MAX is RoHS non-compliant, while all substitute parts are ROHS3 compliant. This compliance status is relevant for applications subject to environmental regulations or customer requirements mandating RoHS-compliant components.

Q: Can I use MAX4289ESA+ in applications requiring -40°C to 125°C operation?

A: No. The MAX4289ESA+ is rated only to 85°C maximum operating temperature. Applications requiring full -40°C to 125°C operation must use ADA4891 series, TS507IDT, or equivalent parts with extended temperature ratings.

Q: What packaging format should I specify for high-volume production?

A: For high-volume surface mount assembly, Tape & Reel packaging is standard. The ADA4891-1ARZ-RL and MAX4289ESA+T are available in Tape & Reel format, matching the original LMP2011MAX packaging type.

Q: Are all substitute parts available in current inventory?

A: All substitute parts listed are active products with current manufacturing status. Inventory availability varies by part number and supplier. Refer to current distributor stock levels for procurement planning.
