LM8262MMX Equivalent & Substitute Parts

Part Overview

The LM8262MMX is a general purpose operational amplifier featuring dual circuits in a rail-to-rail output configuration, manufactured by Texas Instruments. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement continuity. The LM8262MMX operates across a wide supply voltage range and is suitable for applications requiring low-power, dual-channel amplification in compact surface-mount packages.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM8262MMX is determined by the following critical parameters: dual-circuit configuration, rail-to-rail output capability, surface-mount 8-pin package compatibility, and supply voltage range spanning 2.5 V to 22 V. The substitute parts identified maintain these core functional and mechanical requirements.

The LM8262MMX/NOPB represents a direct equivalent from Texas Instruments, differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete). This part maintains identical electrical specifications and package dimensions.

The AD8066ARMZ and AD8066ARMZ-REEL7 from Analog Devices Inc. function as manufacturer-recommended substitutes. While these parts share the dual-circuit, rail-to-rail, 8-pin surface-mount configuration and compatible package dimensions, they exhibit enhanced electrical performance characteristics including higher slew rate (180 V/µs versus 15 V/µs), greater bandwidth (-3dB Bandwidth of 120 MHz versus 24 MHz Gain Bandwidth Product), and lower input bias current (3 pA versus 1.05 µA). The AD8066 series operates within a minimum supply voltage of 5 V, which represents a higher floor than the LM8262MMX at 2.5 V.

Parameter Comparison

Engineering Selection Recommendations

LM8262MMX/NOPB is the primary direct substitute for the obsolete LM8262MMX. This part maintains identical electrical specifications and mechanical compatibility while offering active product status and ROHS3 compliance. Selection of LM8262MMX/NOPB is appropriate for applications requiring exact electrical performance matching and is available in Tape & Reel packaging format suitable for automated assembly processes.

AD8066ARMZ and AD8066ARMZ-REEL7 are manufacturer-recommended alternatives that provide enhanced performance characteristics. These parts are suitable for applications where higher slew rate, greater bandwidth, and lower input bias current provide functional advantages. The AD8066 series requires a minimum supply voltage of 5 V, which must be verified against circuit design requirements. The AD8066ARMZ-REEL7 offers the highest inventory availability and is packaged in Cut Tape & Digi-Reel format. Both AD8066 variants carry ROHS3 compliance and active product status.

Selection between LM8262MMX/NOPB and AD8066 variants depends on supply voltage requirements and performance specifications. Applications operating at supply voltages below 5 V must use LM8262MMX/NOPB. Applications tolerating 5 V minimum supply voltage may benefit from AD8066 enhanced performance metrics.

Frequently Asked Questions (FAQ)

Q: Can the AD8066ARMZ directly replace the LM8262MMX in all applications?

A: The AD8066ARMZ shares the same dual-circuit, rail-to-rail, 8-pin surface-mount package configuration. However, the AD8066ARMZ requires a minimum supply voltage of 5 V, whereas the LM8262MMX operates at 2.5 V minimum. Applications using supply voltages between 2.5 V and 5 V must use LM8262MMX/NOPB. Applications with supply voltages of 5 V or higher may use AD8066ARMZ, which offers superior slew rate and bandwidth performance.

Q: What is the difference between LM8262MMX and LM8262MMX/NOPB?

A: Both parts are electrically identical with matching specifications. The primary differences are product status (Obsolete versus Active) and packaging format (bulk versus Tape & Reel). LM8262MMX/NOPB is the active production equivalent and is recommended for new designs and procurement.

Q: Are the AD8066ARMZ and AD8066ARMZ-REEL7 electrically identical?

A: Yes, both parts are electrically identical. The difference is packaging format: AD8066ARMZ is supplied in Tube packaging, while AD8066ARMZ-REEL7 is supplied in Cut Tape & Digi-Reel format. Selection depends on assembly process requirements and inventory management preferences.

Q: What are the key performance differences between the LM8262MMX and AD8066 series?

A: The AD8066 series provides significantly higher slew rate (180 V/µs versus 15 V/µs), greater bandwidth (120 MHz versus 24 MHz), and lower input bias current (3 pA versus 1.05 µA). The LM8262MMX provides higher output current per channel (100 mA versus 30 mA) and lower minimum supply voltage (2.5 V versus 5 V).

Q: Are all substitute parts RoHS compliant?

A: LM8262MMX/NOPB, AD8066ARMZ, and AD8066ARMZ-REEL7 are all ROHS3 compliant. The original LM8262MMX is RoHS non-compliant.

Q: Can these parts be used interchangeably in PCB layouts?

A: All parts use compatible 8-pin surface-mount packages (8-TSSOP, 8-MSOP) with identical 0.118" width and 3.00mm pitch. PCB footprints are mechanically compatible. Circuit design verification is required to confirm electrical compatibility, particularly regarding supply voltage requirements and performance specifications.
