MAX4482ASA Equivalent & Substitute Parts Reference

Part Overview

The MAX4482ASA is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, configured as a dual-channel (2 circuit) rail-to-rail output device in 8-SOIC surface mount packaging. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The MAX4482ASA operates across a 2.5V to 5.5V supply range with low input bias current (0.1 pA) and is suitable for applications requiring low-power, general-purpose amplification in compact form factors.

Substitute Part Grouping Explanation

Substitution of the MAX4482ASA is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

Dual-channel (2 circuit) configuration
Rail-to-rail output capability
8-SOIC surface mount package (0.154", 3.90mm width)
Supply voltage range compatibility (minimum 2.5V, maximum 5.5V)
Operating temperature range (-40°C to 125°C preferred; -40°C to 85°C acceptable for non-extended-temperature applications)
General-purpose amplifier classification

Secondary Compatibility Parameters:

Input bias current (lower values indicate improved performance)
Slew rate and gain bandwidth product (performance characteristics)
Output current capability per channel
Supply current consumption

Substitute parts are grouped into two categories: direct equivalents (identical electrical and mechanical specifications) and functional alternatives (meeting core substitution criteria with performance variations).

Engineering Selection Recommendations

Direct Equivalent (Packaging Variant): MAX4482ASA+ is the direct equivalent of MAX4482ASA, differing only in packaging format (bulk versus tape & reel). Both are obsolete products from Analog Devices. Selection between these two depends on procurement and assembly requirements rather than electrical performance.

Active Substitutes - Extended Temperature Range (-40°C to 125°C):

LMV822AIDT and LMV822IDT (STMicroelectronics) maintain the full -40°C to 125°C operating range of the original MAX4482ASA. Both are AEC-Q100 qualified automotive-grade components, offering enhanced reliability for demanding applications. These parts provide higher slew rate (1.9 V/µs) and greater output current capability (70 mA) compared to the MAX4482ASA, with compatible 8-SOIC packaging. The primary trade-off is increased supply current consumption (300 µA versus 50 µA).

Active Substitutes - Standard Temperature Range (-40°C to 85°C):

LMV722ID and LMV722IDR (Texas Instruments) offer significantly improved performance characteristics: 5.25 V/µs slew rate, 10 MHz gain bandwidth product, and 52.6 mA output current per channel. These are suitable for applications where extended temperature operation beyond 85°C is not required. Both maintain 8-SOIC packaging compatibility.

LMV822M/NOPB and LMV822MX/NOPB (Texas Instruments) provide a middle-ground performance profile with 2.0 V/µs slew rate and 5.6 MHz gain bandwidth product, operating to 85°C maximum.

LPV358M/NOPB and LPV358MX (Texas Instruments) are performance-matched alternatives to the MAX4482ASA in terms of slew rate (0.1 V/µs) and gain bandwidth product (152 kHz), with ultra-low supply current (15 µA). LPV358MX is designated Last Time Buy status.

Compliance and Certification: All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original MAX4482ASA specifications. LMV822AIDT and LMV822IDT carry AEC-Q100 automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MAX4482ASA with LMV722ID in my existing design?

A: Electrical substitution is possible because both are dual-channel, rail-to-rail, general-purpose amplifiers in 8-SOIC packaging with compatible supply voltage ranges (2.5V to 5.5V). However, LMV722ID has significantly higher performance specifications (5.25 V/µs slew rate versus 0.08 V/µs, 10 MHz GBW versus 140 kHz). Verify that your circuit design does not depend on the lower slew rate or bandwidth characteristics of the MAX4482ASA. Additionally, LMV722ID operates only to 85°C, not 125°C.

Q: What is the difference between LMV822AIDT and LMV822IDT?

A: Both parts are electrically identical STMicroelectronics LMV822 dual-channel amplifiers with identical performance specifications. The difference is in packaging format: LMV822AIDT is supplied in tape & reel format, while LMV822IDT is supplied in cut tape & digi-reel format. Both maintain the full -40°C to 125°C operating range and AEC-Q100 automotive qualification.

Q: Why does the MAX4482ASA+ have higher inventory than the MAX4482ASA?

A: MAX4482ASA+ is the bulk-packaged variant of the same obsolete product. Higher inventory reflects different distribution channels and packaging preferences among suppliers, not a difference in component performance or specifications.

Q: Is LPV358MX a suitable replacement if my application requires ultra-low power consumption?

A: Yes. LPV358MX consumes only 15 µA supply current (compared to 50 µA for MAX4482ASA) and is electrically matched in slew rate (0.1 V/µs) and gain bandwidth product (152 kHz). However, LPV358MX is designated Last Time Buy status, indicating limited future availability. Verify long-term supply chain viability before committing to this part for new production designs.

Q: Can I use LMR932F-GE2 as a substitute?

A: LMR932F-GE2 (Rohm Semiconductor) meets the core substitution criteria: dual-channel, rail-to-rail, general-purpose amplifier in 8-pin surface mount package. However, the package is 8-SOP (0.173", 4.40mm width) rather than 8-SOIC (0.154", 3.90mm width), requiring PCB layout modification. Additionally, LMR932F-GE2 operates only to 85°C maximum. Use this part only if PCB redesign is acceptable and extended temperature operation is not required.

Q: What are the key parameters I should verify when selecting a substitute?

A: Verify the following in order of priority: (1) Dual-channel configuration, (2) Rail-to-rail output, (3) 8-SOIC package compatibility, (4) Supply voltage range (minimum 2.5V, maximum 5.5V), (5) Operating temperature range (confirm whether -40°C to 125°C or -40°C to 85°C is required), (6) Slew rate and gain bandwidth product (confirm your circuit does not depend on specific performance characteristics), (7) Output current capability per channel, (8) Supply current consumption (power budget impact).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original MAX4482ASA.
