MAX4274ABESA Equivalent & Substitute Parts
Part Overview
The MAX4274ABESA 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 2.5V to 5.5V supply range. The MAX4274ABESA is classified as obsolete, necessitating identification of functionally equivalent active alternatives for new designs and ongoing production requirements. Substitute parts must maintain compatibility with the 8-SOIC package footprint and preserve critical electrical performance parameters including supply voltage range, output type, and circuit count.

Engineering Selection Recommendations
For New Designs and Production Transition:
The ADA4692-2ARZ series (including ADA4692-2ARZ, ADA4692-2ARZ-R7, and ADA4692-2ARZ-RL) represents the manufacturer-recommended substitution path. These devices are manufactured by Analog Devices Inc., the same company that produced the MAX4274ABESA. All three variants share identical electrical specifications with enhanced performance across slew rate (1.3V/µs vs. 0.7V/µs), gain bandwidth product (3.6 MHz vs. 2 MHz), and input bias current (0.5 pA vs. 50 pA). Extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C) and ROHS3 compliance provide advantages for modern manufacturing environments. Packaging variants accommodate different procurement workflows: ADA4692-2ARZ (Tube), ADA4692-2ARZ-R7 (Cut Tape & Digi-Reel), and ADA4692-2ARZ-RL (Tape & Reel).
For Cost-Optimized Applications:
The LMV358IDT and LMV358IYDT (STMicroelectronics) offer the lowest supply current (162 µA vs. 330 µA) and highest output current capability (160 mA vs. 65 mA). The LMV358IYDT includes automotive-grade qualification (AEC-Q100) for applications requiring automotive compliance. Trade-off: reduced slew rate (0.45V/µs) and gain bandwidth product (1.3 MHz) compared to the original device. Extended supply voltage range (2.7V to 6V) provides additional design flexibility.
For Bandwidth-Critical Applications:
The LMV772MA/NOPB (Texas Instruments) delivers the highest slew rate (1.4V/µs) and gain bandwidth product (3.5 MHz) among all substitutes. Differential output capability provides additional circuit design options. Higher supply current (600 µA) represents the primary trade-off. Extended operating temperature range (-40°C to 125°C) and ROHS3 compliance support modern production requirements.
For General Purpose Replacement:
The LMR358FJ-GE2 (Rohm Semiconductor) provides balanced performance with 3 MHz gain bandwidth product and 1V/µs slew rate. Lower input bias current (15 nA) and input offset voltage (100 µV) improve signal fidelity. Operating temperature range limited to -40°C to 85°C matches the original device specification.
Compliance Considerations:
All recommended substitutes are ROHS3 compliant, addressing the non-compliant status of the MAX4274ABESA. Selection should prioritize active product status to ensure long-term availability and manufacturing support. The BU7442F-E2, BU7442SF-E2, and CLC2011ISO8MTR are not recommended as primary substitutes due to different amplifier topologies (CMOS and voltage feedback) that may require circuit redesign.
Frequently Asked Questions (FAQ)
Q: Can the ADA4692-2ARZ directly replace the MAX4274ABESA without circuit modifications?
A: The ADA4692-2ARZ maintains identical pinout and package footprint (8-SOIC, 0.154" width) as the MAX4274ABESA. Electrical parameters are compatible across the specified supply voltage range (2.7V to 5V overlaps with 2.5V to 5.5V). Enhanced performance specifications (higher slew rate, lower input bias current, extended temperature range) do not require circuit modifications. Verification of specific application requirements is necessary for designs operating at the 2.5V minimum supply voltage, as the ADA4692-2ARZ minimum is 2.7V.
Q: What is the primary difference between ADA4692-2ARZ, ADA4692-2ARZ-R7, and ADA4692-2ARZ-RL?
A: These three part numbers are electrically identical. Differences exist only in packaging and delivery format. ADA4692-2ARZ is supplied in Tube packaging for manual assembly or small-volume applications. ADA4692-2ARZ-R7 is supplied in Cut Tape & Digi-Reel format for semi-automated pick-and-place equipment. ADA4692-2ARZ-RL is supplied in Tape & Reel format for high-volume automated assembly. Selection depends on manufacturing process requirements and procurement volume.
Q: Why does the LMV358IDT have lower slew rate and gain bandwidth product than the MAX4274ABESA?
A: The LMV358IDT prioritizes power efficiency and cost optimization over bandwidth performance. The 0.45V/µs slew rate and 1.3 MHz gain bandwidth product are suitable for general purpose applications not requiring high-speed signal processing. The primary advantage is reduced supply current (162 µA vs. 330 µA) and significantly higher output current capability (160 mA vs. 65 mA). Applications requiring the original 2 MHz bandwidth should select ADA4692-2ARZ or LMV772MA/NOPB.
Q: Is the LMV358IYDT suitable for automotive applications?
A: The LMV358IYDT is qualified to AEC-Q100 automotive standards and carries automotive-grade designation. Electrical specifications are identical to the commercial-grade LMV358IDT. Selection of the automotive variant is required only for applications subject to automotive qualification requirements. For non-automotive applications, the LMV358IDT provides identical performance at potentially lower cost.
Q: Can the BU7442F-E2 or BU7442SF-E2 replace the MAX4274ABESA?
A: The BU7442 series uses CMOS amplifier topology, differing fundamentally from the MAX4274ABESA general purpose topology. While both are dual-circuit 8-SOIC devices, the BU7442 exhibits significantly lower slew rate (0.3V/µs vs. 0.7V/µs), reduced gain bandwidth product (600 kHz vs. 2 MHz), and lower output current capability (10 mA vs. 65 mA). Circuit redesign is required for BU7442 substitution. This device is recommended only for applications where CMOS topology provides specific advantages such as extremely low input bias current (1 pA).
Q: What is the significance of the extended operating temperature range in substitute parts?
A: The MAX4274ABESA operates from -40°C to 85°C. Most substitute parts extend this range to -40°C to 125°C. Extended temperature range provides design margin for applications operating in high-temperature environments and allows use in automotive and industrial applications with stricter thermal requirements. For applications limited to -40°C to 85°C, the extended range provides no functional advantage but does not restrict use.
Q: How does the supply voltage range difference affect substitution?
A: The MAX4274ABESA operates from 2.5V to 5.5V. Most substitutes operate from 2.7V to 5V or 2.7V to 6V. The 0.2V difference at the minimum supply voltage (2.5V vs. 2.7V) may affect designs operating at the lower supply limit. Applications using 2.5V supply voltage must verify that the substitute part's 2.7V minimum does not violate circuit requirements. The LMV358IDT and LMV358IYDT extend the maximum to 6V, providing additional design flexibility for higher supply voltage applications.
Q: What inventory considerations should guide substitute part selection?
A: Current inventory levels vary significantly among substitutes. LMV358IDT shows the highest availability (215,400 pcs), followed by ADA4692-2ARZ-R7 (4,616 pcs) and BU7442SF-E2 (5,660 pcs). For applications requiring immediate component availability, LMV358IDT offers the shortest lead time. For designs prioritizing manufacturer-recommended substitution, ADA4692-2ARZ variants provide adequate inventory across all three packaging options.
