MAX4274ADESA Equivalent & Substitute Parts
Part Overview
The MAX4274ADESA is a general-purpose operational amplifier featuring dual circuits in an 8-SOIC surface-mount package, manufactured by Analog Devices Inc./Maxim Integrated. This device provides rail-to-rail output capability with a 2 MHz gain-bandwidth product and operates across a 2.5 V to 5.5 V supply range. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain compatibility with the 8-SOIC package footprint and deliver equivalent electrical performance within the specified operating parameters.

Engineering Selection Recommendations
Recommended Primary Substitutes:
The ADA4692-2ARZ series (ADA4692-2ARZ, ADA4692-2ARZ-R7, ADA4692-2ARZ-RL) represents the optimal replacement for MAX4274ADESA applications. All three variants share identical electrical specifications and differ only in packaging format (Tube, Cut Tape & Digi-Reel, and Tape & Reel respectively). These parts deliver superior performance with 1.3 V/µs slew rate, 3.6 MHz gain-bandwidth product, and significantly reduced input bias current (0.5 pA). Extended operating temperature range (-40°C to 125°C) and RoHS3 compliance provide enhanced design flexibility. Selection among the three variants depends on procurement and assembly requirements.
Secondary Substitutes for General-Purpose Applications:
LMR358FJ-GE2 and LMV772MA/NOPB provide active-status alternatives with general-purpose amplifier classification. LMR358FJ-GE2 maintains the -40°C to 85°C temperature range matching the original part while offering improved slew rate (1 V/µs) and gain-bandwidth product (3 MHz). LMV772MA/NOPB and LMV772MAX/NOPB extend operating temperature to 125°C with differential output capability and superior slew rate (1.4 V/µs), though supply current is elevated at 600 µA.
LMV358IYDT (STMicroelectronics) qualifies as an automotive-grade alternative with AEC-Q100 qualification and extended supply voltage range (2.7 V to 6 V). This part exhibits lower slew rate (0.45 V/µs) and reduced gain-bandwidth product (1.3 MHz) but provides exceptional output current capability (160 mA per channel).
Limited Compatibility Alternatives:
BU7442F-E2 and BU7442SF-E2 are CMOS amplifiers with significantly reduced performance envelope (0.3 V/µs slew rate, 600 kHz gain-bandwidth product). These parts are suitable only for applications with relaxed bandwidth requirements and benefit from ultra-low supply current (100 µA). Extended supply voltage range (1.7 V to 5.5 V) enables single-cell battery operation.
CLC2011ISO8MTR (voltage feedback amplifier, obsolete status) exhibits high slew rate (9 V/µs) and elevated input bias current (90 nA), making it unsuitable for precision applications requiring low input bias characteristics.
Compliance and Certification Considerations:
All recommended active substitutes carry RoHS3 compliance certification. The original MAX4274ADESA is RoHS non-compliant; migration to compliant alternatives is necessary for new designs and regulatory adherence. REACH status is unaffected across all listed parts. Moisture sensitivity level remains MSL 1 (Unlimited) for all candidates, eliminating moisture-related design constraints.
Frequently Asked Questions (FAQ)
Q1: Can ADA4692-2ARZ variants be used as direct drop-in replacements for MAX4274ADESA?
A: ADA4692-2ARZ, ADA4692-2ARZ-R7, and ADA4692-2ARZ-RL share identical electrical specifications and 8-SOIC package footprint with MAX4274ADESA. Pin configuration and functional behavior are compatible. The primary difference is packaging format (Tube, Cut Tape & Digi-Reel, or Tape & Reel). Verify PCB layout compatibility with the 0.154" package width specification before implementation.
Q2: What is the significance of the three ADA4692-2ARZ packaging variants?
A: The three variants (ADA4692-2ARZ, ADA4692-2ARZ-R7, ADA4692-2ARZ-RL) differ only in delivery format. ADA4692-2ARZ ships in Tube packaging for manual assembly. ADA4692-2ARZ-R7 uses Cut Tape & Digi-Reel format for semi-automated pick-and-place equipment. ADA4692-2ARZ-RL employs Tape & Reel format for fully automated assembly lines. Electrical performance and pinout are identical across all three.
Q3: Why does LMV358IYDT have higher output current capability than MAX4274ADESA?
A: LMV358IYDT specifies 160 mA output current per channel compared to MAX4274ADESA's 65 mA. This enhanced capability results from different internal circuit topology and output stage design. Applications requiring high-impedance loads or direct LED driving benefit from this increased output current. However, this parameter does not affect substitution compatibility for standard operational amplifier applications.
Q4: Is the extended temperature range of ADA4692-2ARZ (-40°C to 125°C) beneficial for all applications?
A: Extended temperature range provides design margin for applications operating in elevated ambient conditions or requiring thermal cycling stress testing. For applications constrained to -40°C to 85°C operation, the extended range offers no functional advantage but does not introduce compatibility issues. Thermal management and PCB layout remain unchanged.
Q5: Why are BU7442F-E2 and BU7442SF-E2 classified as limited compatibility alternatives?
A: BU7442 series devices are CMOS amplifiers with fundamentally different performance characteristics. Slew rate (0.3 V/µs) and gain-bandwidth product (600 kHz) are substantially lower than MAX4274ADESA. Input offset voltage (1 mV) is twice the original specification. These parts are suitable only for low-bandwidth, low-power applications. Existing designs optimized for MAX4274ADESA performance cannot migrate to BU7442 without circuit redesign.
Q6: What does RoHS3 compliance mean for component selection?
A: RoHS3 compliance certifies that the component contains no restricted hazardous substances (lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers) above specified thresholds. This certification is mandatory for products sold in European Union markets and increasingly required by global OEMs. Migration from RoHS non-compliant MAX4274ADESA to RoHS3-compliant alternatives ensures regulatory compliance and supply chain continuity.
Q7: Can LMV772MA/NOPB and LMV772MAX/NOPB be used interchangeably?
A: LMV772MA/NOPB and LMV772MAX/NOPB are electrically identical and differ only in packaging format (Tube versus Cut Tape & Digi-Reel). Pin configuration, electrical specifications, and functional behavior are identical. Selection depends on assembly process requirements. Both parts carry identical inventory levels and active product status.
Q8: What is the practical impact of input bias current differences between substitute parts?
A: MAX4274ADESA specifies 50 pA input bias current. ADA4692-2ARZ reduces this to 0.5 pA, while LMV772 series achieves 0.23 pA. Lower input bias current reduces errors in high-impedance transimpedance amplifier circuits and precision instrumentation applications. For standard voltage amplifier configurations with impedance below 1 MΩ, input bias current differences have negligible impact on circuit performance.
Q9: Why is CLC2011ISO8MTR classified as obsolete despite active inventory?
A: CLC2011ISO8MTR carries obsolete product status designation from the manufacturer, indicating end-of-life status and no commitment to future availability. Although current inventory exists, procurement of this part for new designs is not recommended. Active-status alternatives provide superior long-term supply assurance and design continuity.
Q10: How should package width specification (0.154" versus 0.173") be evaluated for PCB compatibility?
A: MAX4274ADESA specifies 8-SOIC package with 0.154" width (3.90mm). Most substitute parts maintain this specification. BU7442 series specifies 0.173" width (4.40mm), representing a 0.019" (0.5mm) increase. This difference may affect PCB layout if components are placed in close proximity. Verify PCB footprint library definitions and component placement clearances before selecting BU7442 variants for existing designs.
