Substitute Part Grouping Explanation

Substitute parts for the LM8272MM are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Direct Substitutes): LM8272MM/NOPB and LM8272MMX/NOPB are parametric equivalents of the LM8272MM. These parts share identical electrical specifications across all critical parameters: 15 V/µs slew rate, 15 MHz gain bandwidth product, 12.5 MHz -3dB bandwidth, 2 µA input bias current, 700 µV input offset voltage, 1.9 mA supply current per dual channel, and 65 mA output current per channel. All three variants operate within the 2.5 V to 24 V supply range and maintain the same -40°C to 85°C operating temperature specification. The primary differences are packaging format (Cut Tape & Digi-Reel® versus individual variants) and product status (Last Time Buy versus Active).

Manufacturer Recommended Substitutes (Performance Upgrades): AD8066ARMZ and AD8066ARMZ-REEL7 (Analog Devices Inc.) are manufacturer-recommended alternatives classified as voltage feedback amplifiers. These devices maintain the dual-channel, rail-to-rail output configuration and 8-MSOP package compatibility. However, they exhibit enhanced electrical performance: 180 V/µs slew rate (12× faster), 120 MHz -3dB bandwidth (9.6× wider), 3 pA input bias current (0.15% of LM8272MM), and 400 µV input offset voltage (57% lower). The AD8066 series requires a minimum 5 V supply (versus 2.5 V for LM8272MM) and operates within the 5 V to 24 V range. Supply current increases to 6.6 mA per dual channel, and output current decreases to 30 mA per channel.

Alternative Substitute (Automotive Grade): TSX922IYST (STMicroelectronics) is a CMOS amplifier offering automotive qualification (AEC-Q100) with extended operating temperature range (-40°C to 125°C). This device maintains dual-channel, rail-to-rail output in an 8-MiniSO package. Electrical characteristics include 17 V/µs slew rate, 10 MHz gain bandwidth product, 10 pA input bias current, and 5 mV input offset voltage. The TSX922IYST operates within a 4 V to 16 V supply range with 2.8 mA supply current per dual channel and 74 mA output current per channel.

Key Parameters Determining Substitution:

Dual-channel configuration (2 circuits)
Rail-to-rail output capability
Surface mount package (8-TSSOP/8-MSOP form factor)
Operating temperature range compatibility
Supply voltage range overlap
Output current capability (minimum 30 mA per channel)

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

LM8272MM/NOPB and LM8272MMX/NOPB are suitable for direct substitution when component availability is the primary concern. Both parts maintain identical electrical specifications and operating characteristics. LM8272MMX/NOPB is preferred for new designs due to its Active product status, ensuring extended availability and manufacturing support. LM8272MM/NOPB remains available in higher inventory quantities (38,100 units) and is suitable for immediate procurement needs.

For Performance-Enhanced Applications:

AD8066ARMZ and AD8066ARMZ-REEL7 are recommended when circuit design permits higher supply voltage (minimum 5 V) and increased power consumption. These devices provide significant performance improvements: 12× faster slew rate, 9.6× wider bandwidth, and substantially lower input bias current. AD8066ARMZ-REEL7 is preferred for high-volume production due to Cut Tape & Digi-Reel® packaging and superior inventory availability (46,449 units). AD8066ARMZ in Tube packaging is suitable for lower-volume applications.

For Automotive and Extended Temperature Applications:

TSX922IYST is selected when automotive qualification (AEC-Q100) and extended operating temperature range (-40°C to 125°C) are design requirements. This device maintains compatibility with the dual-channel, rail-to-rail output configuration while offering higher output current capability (74 mA per channel). Supply voltage range limitation (4 V to 16 V maximum) must be verified against application requirements.

Compliance and Certification Considerations:

All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes. REACH compliance status is consistent across all alternatives. Selection should prioritize parts with Active product status for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q1: Can LM8272MM/NOPB be used as a direct replacement for LM8272MM?

A: Yes. LM8272MM/NOPB is a parametric equivalent with identical electrical specifications, operating temperature range, and supply voltage range. The primary difference is packaging format and product status. Both parts are classified as Last Time Buy, indicating limited future availability.

Q2: What is the key difference between LM8272MMX/NOPB and LM8272MM/NOPB?

A: Electrical specifications are identical. The primary distinction is product status: LM8272MMX/NOPB is Active (ongoing production), while LM8272MM/NOPB is Last Time Buy (discontinued). For new designs, LM8272MMX/NOPB is recommended to ensure long-term component availability.

Q3: Can AD8066ARMZ replace LM8272MM in all applications?

A: AD8066ARMZ is not a direct replacement for all applications. While both are dual-channel, rail-to-rail amplifiers in compatible packages, AD8066ARMZ requires a minimum 5 V supply voltage (LM8272MM operates from 2.5 V). Applications operating at supply voltages below 5 V cannot use AD8066ARMZ. Additionally, AD8066ARMZ exhibits higher supply current (6.6 mA versus 1.9 mA) and lower output current per channel (30 mA versus 65 mA). Verify circuit design compatibility before substitution.

Q4: What are the advantages of AD8066ARMZ over LM8272MM?

A: AD8066ARMZ provides enhanced performance specifications: 180 V/µs slew rate (versus 15 V/µs), 120 MHz -3dB bandwidth (versus 12.5 MHz), 3 pA input bias current (versus 2 µA), and 400 µV input offset voltage (versus 700 µV). These improvements are suitable for high-speed signal processing and precision measurement applications. The trade-off is increased power consumption and higher minimum supply voltage requirement.

Q5: Is TSX922IYST suitable for non-automotive applications?

A: Yes. TSX922IYST can be used in non-automotive applications. The AEC-Q100 automotive qualification is an additional certification that does not restrict use in other markets. The primary technical advantage is the extended operating temperature range (-40°C to 125°C), which is beneficial for industrial and high-temperature environments. Supply voltage range limitation (4 V to 16 V maximum) must be verified against application requirements.

Q6: What packaging formats are available for these substitute parts?

A: LM8272MM variants are supplied in 8-VSSOP packages with Cut Tape (CT) & Digi-Reel® or individual packaging options. AD8066ARMZ is available in 8-MSOP Tube packaging, while AD8066ARMZ-REEL7 is supplied in Cut Tape (CT) & Digi-Reel® format. TSX922IYST is supplied in 8-MiniSO Tape & Reel (TR) packaging. All packages are surface mount compatible with standard PCB assembly processes.

Q7: Are there supply voltage compatibility issues when substituting these parts?

A: Yes. Supply voltage range varies across alternatives. LM8272MM operates from 2.5 V to 24 V. AD8066ARMZ requires 5 V to 24 V minimum. TSX922IYST operates from 4 V to 16 V maximum. Applications with supply voltages below 4 V cannot use TSX922IYST. Applications with supply voltages below 5 V cannot use AD8066ARMZ. Verify circuit supply voltage specifications before selecting a substitute part.

Q8: Which substitute part has the highest inventory availability?

A: AD8066ARMZ-REEL7 has the highest inventory availability with 46,449 units in stock. This part is recommended for high-volume production requirements and applications where immediate procurement is necessary. LM8272MM/NOPB has 38,100 units available, making it the second-highest inventory option.
