The substitute parts are grouped into two categories based on functional alignment:
Category 1: Direct General-Purpose Substitutes (ISL28213FBZ, ISL28213FBZ-T13, LMV358LIDT, LMV358Q1MA/NOPB, LMV358Q1MAX/NOPB, LMV358Q3MA/NOPB) — These devices maintain the general-purpose amplifier classification, dual-circuit topology, rail-to-rail output, and 8-SOIC packaging. All operate within the 2.5V to 5.5V supply range and are active products with RoHS3 compliance.
Category 2: Enhanced Performance Substitutes (ISL28214FBZ, ISL28214FBZ-T13, LMP2022MA/NOPB, LMP2022MAX/NOPB) — These devices provide higher slew rates and gain bandwidth products while maintaining dual-circuit configuration and 8-SOIC packaging. The ISL28214 series offers increased performance metrics; the LMP2022 series introduces zero-drift amplifier technology with superior offset voltage characteristics.
All substitute parts maintain the 8-SOIC surface-mount package and support the full 2.5V to 5.5V supply voltage range of the original device.

The ISL28214FBZ and ISL28214FBZ-T13 (Renesas Electronics) offer superior performance with 2.5V/µs slew rate and 5MHz gain bandwidth product, exceeding the original device specifications. These remain general-purpose, dual-circuit, rail-to-rail amplifiers in 8-SOIC packaging with ROHS3 compliance and active product status. Higher supply current (300µA vs. 37µA) and output current (31mA vs. 22mA) must be evaluated against application power budgets.
For Precision-Critical Applications:
The LMP2022MA/NOPB and LMP2022MAX/NOPB (Texas Instruments) introduce zero-drift amplifier technology with 0.4µV input offset voltage, substantially lower than the original 200µV specification. These devices maintain dual-circuit configuration and 8-SOIC packaging with ROHS3 compliance and active status. Increased supply current (1.1mA) and output current (50mA) reflect the enhanced precision architecture.
For Cost-Optimized General-Purpose Applications:
The LMV358LIDT (STMicroelectronics) provides a cost-effective general-purpose alternative with active product status and ROHS3 compliance. This device maintains rail-to-rail output and 8-SOIC packaging. Operating temperature range extends to 125°C. Trade-offs include reduced gain bandwidth product (1.3MHz) and increased input bias current (27nA).
For Automotive-Grade Applications:
The LMV358Q1MA/NOPB, LMV358Q1MAX/NOPB, and LMV358Q3MA/NOPB (Texas Instruments) are AEC-Q100 qualified automotive-grade devices with active status and ROHS3 compliance. All maintain dual-circuit, general-purpose, rail-to-rail configuration in 8-SOIC packaging. The Q1 variants support -40°C to 125°C; the Q3 variant supports -40°C to 85°C. These are suitable for automotive and industrial applications requiring qualification documentation.
All recommended substitutes are active products with current manufacturing support and RoHS3 compliance, addressing the obsolescence and compliance limitations of the MAX4075BEESA.
Frequently Asked Questions (FAQ)
Q1: Can the ISL28213FBZ directly replace the MAX4075BEESA without PCB modifications?
The ISL28213FBZ shares identical 8-SOIC pinout and package dimensions (0.154", 3.90mm width) with the MAX4075BEESA. Both are dual-circuit general-purpose amplifiers with rail-to-rail output. Pin-for-pin compatibility is confirmed. However, the slew rate increase (0.1V/µs to 1V/µs) and gain bandwidth product decrease (4MHz to 2MHz) may affect circuit behavior in applications with specific frequency response requirements. Functional verification is necessary for timing-critical circuits.
Q2: What is the key difference between ISL28213FBZ and ISL28214FBZ?
Both devices are Renesas Electronics general-purpose dual-circuit amplifiers in 8-SOIC packaging with ROHS3 compliance. The ISL28214FBZ provides enhanced performance: slew rate of 2.5V/µs (versus 1V/µs) and gain bandwidth product of 5MHz (versus 2MHz). The ISL28214FBZ also delivers higher output current per channel (31mA versus 22mA). Supply current consumption increases from 90µA to 300µA. Selection depends on application bandwidth and power budget requirements.
Q3: Why does the LMP2022 series have higher supply current than other substitutes?
The LMP2022MA/NOPB and LMP2022MAX/NOPB employ zero-drift amplifier architecture, which uses internal chopper-stabilization circuitry to achieve extremely low input offset voltage (0.4µV). This precision enhancement requires additional quiescent current (1.1mA total for dual channels). Applications requiring offset voltage specifications below 500µV benefit from this trade-off; general-purpose applications may select lower-power alternatives.
Q4: Are the LMV358Q1 variants suitable for non-automotive applications?
The LMV358Q1MA/NOPB and LMV358Q1MAX/NOPB are AEC-Q100 qualified automotive-grade devices. They function in non-automotive applications; however, automotive qualification adds manufacturing cost. For non-automotive general-purpose applications, the LMV358LIDT or ISL28213FBZ offer equivalent functionality at lower cost without automotive-specific qualification overhead.
Q5: What is the significance of packaging variants (Tube vs. Tape & Reel)?
ISL28213FBZ and ISL28214FBZ are supplied in Tube packaging; ISL28213FBZ-T13 and ISL28214FBZ-T13 are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly lines and high-volume production. Tube packaging is suitable for lower-volume applications or manual assembly. Electrical specifications are identical; packaging selection depends on manufacturing process requirements.
Q6: Can the MAX4075BEESA be used in new designs given its obsolete status?
The MAX4075BEESA is classified as obsolete, indicating discontinued manufacturing and limited inventory availability. Analog Devices Inc./Maxim Integrated no longer supports this device. New designs must incorporate active substitute components to ensure long-term supply chain continuity, manufacturing support, and compliance with current environmental regulations (RoHS3). All recommended substitutes are active products with confirmed ongoing production.
Q7: Which substitute offers the best balance of performance and power consumption?
The ISL28213FBZ provides optimal balance for general-purpose applications: 1V/µs slew rate and 2MHz gain bandwidth product with moderate supply current (90µA). This device maintains the original device's general-purpose classification and rail-to-rail output while offering active product status and ROHS3 compliance. For applications requiring higher bandwidth, the ISL28214FBZ increases performance at the cost of 300µA supply current.
Q8: Are all substitute parts compatible with the original 2.5V to 5.5V supply range?
The ISL28213FBZ, ISL28214FBZ, and LMP2022 series support 1.8V to 5.5V supply range, which encompasses the original 2.5V to 5.5V specification. The LMV358 variants support 2.7V to 5.5V, which is compatible with the original minimum of 2.5V for most applications but may require verification at the 2.5V lower boundary. All substitutes support the full 5.5V maximum.
Q9: What compliance certifications apply to the substitute parts?
All recommended substitute parts are ROHS3 compliant and REACH unaffected. The LMV358Q1MA/NOPB, LMV358Q1MAX/NOPB, and LMV358Q3MA/NOPB carry AEC-Q100 automotive qualification. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001. Compliance documentation is available from respective manufacturers.
Q10: How do input bias current differences affect circuit design?
The MAX4075BEESA specifies 0.8pA input bias current. Substitutes range from 3pA (ISL28213/ISL28214) to 27nA (LMV358LIDT). Higher input bias current increases input impedance loading and may affect high-impedance signal sources. For applications with source impedances exceeding 1MΩ, the ISL28213 or ISL28214 series (3pA) are preferred. For general-purpose applications below 100kΩ source impedance, all substitutes are acceptable.
