Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM8272MM/NOPB is determined by the following critical parameters:

Primary Substitution Criteria:

• Dual-channel configuration (2 circuits)
• Rail-to-rail output capability
• 8-pin surface mount package (8-VSSOP, 8-MSOP, or 8-TSSOP)
• Operating temperature range: -40°C to 85°C minimum
• Supply voltage span: 2.5V to 24V minimum
• General-purpose amplifier classification

Substitute parts are grouped into two categories:

1. Parametric Equivalents (Texas Instruments LM8272 Series): Parts that maintain identical electrical specifications and differ only in packaging format or product status. These include LM8272MM and LM8272MMX/NOPB.

2. Manufacturer-Recommended Alternatives: Parts from alternative manufacturers (Analog Devices Inc., Rohm Semiconductor) that meet the core functional requirements but may exhibit different electrical performance characteristics within acceptable application ranges.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended for Immediate Substitution):

LM8272MM and LM8272MMX/NOPB are direct parametric equivalents of LM8272MM/NOPB. Both maintain identical electrical specifications across all measured parameters. LM8272MMX/NOPB carries Active product status, providing superior long-term availability compared to the Last Time Buy designation of the original part. These parts are suitable for direct pin-for-pin replacement without circuit redesign.

Manufacturer-Recommended Alternatives (Conditional Substitution):

AD8066ARMZ and AD8066ARMZ-REEL7 (Analog Devices Inc., FastFET™ Series) are manufacturer-recommended alternatives. These parts provide superior performance in slew rate (180V/µs versus 15V/µs) and bandwidth (120 MHz versus 12.5 MHz), with lower input bias current (3 pA versus 2 µA). However, they require minimum supply voltage of 5V (versus 2.5V for LM8272MM/NOPB) and exhibit higher supply current consumption (6.6 mA per channel versus 1.9 mA). AD8066ARMZ-REEL7 offers higher inventory availability (46,449 units) and Active product status. These parts are suitable for applications where increased bandwidth and slew rate are beneficial and supply voltage constraints permit 5V minimum operation.

BA4560RFVM-TR and BA4560RFVT-E2 (Rohm Semiconductor) are general-purpose alternatives with reduced performance specifications. Slew rate is 4V/µs, gain bandwidth product is 4 MHz, and output current per channel is 25 mA. Supply voltage minimum is 8V. BA4560RFVT-E2 carries Not For New Designs status. These parts are suitable only for applications with relaxed bandwidth and slew rate requirements and where 8V minimum supply voltage is acceptable.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and EAR99 export classification. All parts are suitable for operating temperature range -40°C to 85°C minimum. Selection should prioritize parts with Active product status for new designs and long-term supply security.

Frequently Asked Questions (FAQ)

Q1: Can LM8272MMX/NOPB directly replace LM8272MM/NOPB?

A: Yes. LM8272MMX/NOPB is a parametric equivalent with identical electrical specifications. The primary advantage is Active product status versus Last Time Buy, ensuring superior long-term availability. Pin configuration and package dimensions are identical.

Q2: What are the key differences between LM8272MM/NOPB and AD8066ARMZ?

A: Both are dual-channel, rail-to-rail amplifiers in 8-pin surface mount packages. AD8066ARMZ provides significantly higher slew rate (180V/µs versus 15V/µs), higher bandwidth (120 MHz versus 12.5 MHz), and lower input bias current (3 pA versus 2 µA). However, AD8066ARMZ requires minimum 5V supply voltage (LM8272MM/NOPB operates from 2.5V), consumes higher supply current (6.6 mA per channel versus 1.9 mA), and provides lower output current per channel (30 mA versus 65 mA). Substitution is appropriate for high-speed applications where supply voltage constraints permit 5V minimum operation.

Q3: Are BA4560 series parts suitable substitutes for LM8272MM/NOPB?

A: BA4560 series parts meet the dual-channel, 8-pin surface mount package requirements but exhibit significantly reduced performance. Slew rate is 4V/µs (versus 15V/µs), bandwidth is 4 MHz (versus 12.5 MHz), and output current is 25 mA per channel (versus 65 mA). Supply voltage minimum is 8V (versus 2.5V). These parts are suitable only for applications with relaxed bandwidth and slew rate requirements and where 8V minimum supply voltage is acceptable.

Q4: What packaging options are available for LM8272 series substitutes?

A: LM8272MM/NOPB and LM8272MM are supplied in 8-VSSOP package (0.118", 3.00mm width). LM8272MMX/NOPB is also available in 8-VSSOP. AD8066ARMZ and AD8066ARMZ-REEL7 are supplied in 8-MSOP package (0.118", 3.00mm width). BA4560RFVM-TR is supplied in 8-MSOP (0.110", 2.80mm width). BA4560RFVT-E2 is supplied in 8-TSSOP (0.173", 4.40mm width). All packages are surface mount compatible with standard PCB assembly processes.

Q5: Which substitute part offers the best long-term availability?

A: LM8272MMX/NOPB and AD8066ARMZ-REEL7 both carry Active product status. AD8066ARMZ-REEL7 offers the highest inventory availability (46,449 units) among all listed substitutes. For applications requiring LM8272MM/NOPB electrical specifications with superior long-term supply security, LM8272MMX/NOPB is the preferred choice. For applications where higher bandwidth and slew rate are beneficial, AD8066ARMZ-REEL7 is recommended.

Q6: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (LM8272MM, LM8272MMX/NOPB, AD8066ARMZ, AD8066ARMZ-REEL7, BA4560RFVM-TR, and BA4560RFVT-E2) are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q7: What is the significance of "Last Time Buy" status for LM8272MM/NOPB?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part. Existing inventory is available for purchase, but no future production is planned. This necessitates identification of substitute parts for design continuity and long-term supply chain planning. LM8272MMX/NOPB (Active status) is the recommended substitute to maintain identical electrical specifications with assured future availability.
