MAX4075BCEUA Equivalent & Substitute Parts

Part Overview

The MAX4075BCEUA is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, featuring dual circuits in a rail-to-rail configuration. This device is classified as Obsolete and is no longer in active production. The part operates across a 2.5V to 5.5V supply range with a gain bandwidth product of 4 MHz and slew rate of 0.1V/µs, making it suitable for low-speed analog signal conditioning applications.

Due to its obsolete status, identifying equivalent and substitute parts is essential for design continuity, production support, and long-term component availability. Substitute parts must maintain compatibility across key electrical parameters including supply voltage range, output type, circuit count, and package form factor.

Rail-to-rail output capability
Surface mount 8-pin package (8-MSOP, 8-TSSOP, or 8-VSSOP variants)
Supply voltage range overlap with 2.5V to 5.5V specification
General-purpose amplifier classification

Secondary Compatibility Considerations:

Gain bandwidth product within operational range (1 MHz to 6.25 MHz acceptable for low-speed applications)

The LMP2022MM/NOPB, LMP2022MME/NOPB, and LMP2022MMX/NOPB from Texas Instruments provide zero-drift amplifier performance with exceptional input offset voltage of 0.4 µV. These variants are functionally identical with different packaging options (Cut Tape, Digi-Reel, or Tape & Reel). Supply voltage range extends to 2.2V minimum, and operating temperature reaches 125°C. Higher supply current (1.1 mA x2 channels) and output current (50 mA per channel) support precision measurement applications. All variants are ROHS3 compliant with active product status.

For Audio and High-Performance Applications:

The LME49726MY/NOPB and LME49726MYX/NOPB from Texas Instruments deliver audio-grade performance with 6.25 MHz gain bandwidth product and 3.7 V/µs slew rate. These devices provide 350 mA output current per channel, supporting higher-load applications. Exposed pad package design improves thermal performance. Both variants are ROHS3 compliant and active, with operating temperature range of -40°C to 85°C.

Compliance and Availability:

All recommended substitutes carry ROHS3 compliance status, addressing environmental and regulatory requirements. Active product status across all alternatives ensures continued manufacturing support, documented availability, and stable pricing. The MAX4075BCEUA's obsolete status necessitates migration to one of these active alternatives for new designs or production continuation.

Frequently Asked Questions (FAQ)

Q: Can the ISL28213FUZ-T7 directly replace the MAX4075BCEUA in existing designs?

A: The ISL28213FUZ-T7 maintains functional compatibility across dual-circuit, rail-to-rail, and 8-MSOP package specifications. Supply voltage range (1.8V to 5.5V) encompasses the MAX4075BCEUA requirement (2.5V to 5.5V). Pin-to-pin compatibility exists for standard dual-amplifier configurations. However, the lower gain bandwidth product (2 MHz versus 4 MHz) and different slew rate (1 V/µs versus 0.1 V/µs) may affect high-frequency performance in bandwidth-critical applications. Circuit validation is required for frequency-dependent designs.

Q: What is the key difference between the ISL28213FUZ-T7 and ISL28214FUZ?

A: Both devices are Renesas general-purpose dual amplifiers in 8-MSOP packages with identical supply voltage and temperature ranges. The ISL28214FUZ provides enhanced performance with 5 MHz gain bandwidth product (versus 2 MHz) and 2.5 V/µs slew rate (versus 1 V/µs). Supply current consumption increases to 300 µA (x2 channels) and output current to 31 mA per channel. Selection depends on application bandwidth requirements and power budget constraints.

Q: Why does the LMP2022 series show higher supply current than the MAX4075BCEUA?

A: The LMP2022 series implements zero-drift amplifier architecture, which employs continuous offset correction circuitry. This precision enhancement requires additional quiescent current (1.1 mA x2 channels) compared to the MAX4075BCEUA (37 µA x2 channels). The trade-off delivers exceptional input offset voltage of 0.4 µV versus 200 µV, making the LMP2022 suitable for precision measurement and instrumentation applications where offset drift is critical.

Q: Is the LME49726 suitable for general-purpose applications, or is it audio-specific?

A: The LME49726 is classified as an audio amplifier but functions as a general-purpose dual amplifier with rail-to-rail output. The "audio" designation reflects optimized performance characteristics including high slew rate (3.7 V/µs) and high output current (350 mA per channel), which benefit audio signal processing. General-purpose applications with higher bandwidth and output current requirements can utilize this device. However, the 700 µA supply current (x2 channels) exceeds low-power design constraints.

Q: What packaging options are available for the LMP2022 series?

A: The LMP2022 series offers three packaging variants with identical electrical specifications: LMP2022MM/NOPB (Cut Tape & Digi-Reel), LMP2022MME/NOPB (Cut Tape & Digi-Reel), and LMP2022MMX/NOPB (Tape & Reel). All use 8-VSSOP package form factor. Selection depends on procurement and assembly requirements. Tape & Reel packaging (MMX variant) is standard for high-volume production, while Cut Tape variants support lower-volume or prototype applications.

Q: Can the LMV358Q1MM/NOPB operate at the minimum 2.5V supply voltage of the MAX4075BCEUA?

A: The LMV358Q1MM/NOPB specifies a minimum supply voltage of 2.7V, which exceeds the MAX4075BCEUA minimum of 2.5V. Applications requiring operation at 2.5V supply voltage cannot use the LMV358Q1MM/NOPB. The ISL28213FUZ-T7 or ISL28214FUZ, with 1.8V minimum supply voltage, provide broader voltage compatibility for low-voltage designs.

Q: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitute parts carry ROHS3 compliance certification. The MAX4075BCEUA is listed as RoHS non-compliant, reflecting its obsolete status and pre-RoHS manufacturing period. Migration to any of the recommended substitutes ensures compliance with current environmental and regulatory standards for new production and design implementations.

Q: What is the temperature range limitation for the LME49726 compared to other substitutes?

A: The LME49726 series operates across -40°C to 85°C, which is narrower than the MAX4075BCEUA range of -40°C to 70°C at the upper limit. However, the LME49726 extends the lower temperature specification to match the MAX4075BCEUA. For applications requiring operation above 85°C, the ISL28213FUZ-T7, ISL28214FUZ, LMP2022 series, or LMV358Q1MM/NOPB (all rated to 125°C) are required.

Q: How do input bias current specifications affect substitute selection?

A: Input bias current ranges from 0.2 pA (LME49726) to 15 nA (LMV358Q1MM/NOPB). The MAX4075BCEUA specifies 0.8 pA. High-impedance input circuits (>1 MΩ) are sensitive to input bias current, which causes voltage offset errors. For precision high-impedance applications, the LME49726 (0.2 pA) or LMP2022 (25 pA) provide superior performance. General-purpose applications tolerate the higher bias current of the LMV358Q1MM/NOPB.
