Engineering Selection Recommendations
ISL28213FUZ-T7 (Renesas Electronics)
The ISL28213FUZ-T7 is an active general-purpose dual operational amplifier with rail-to-rail output, housed in an 8-MSOP package. This device maintains compatibility with the MAX4075ADEUA+ footprint and supply voltage range (1.8V to 5.5V). The ISL28213FUZ-T7 offers extended operating temperature range (-40°C to 125°C) and is ROHS3 compliant with MSL-2 rating. The slew rate of 1 V/µs and gain bandwidth product of 2 MHz represent reduced performance compared to the original part, suitable for applications where lower bandwidth is acceptable.
LME49726MY/NOPB and LME49726MYX/NOPB (Texas Instruments)
The LME49726 series comprises audio-grade dual operational amplifiers with rail-to-rail output in 8-HVSSOP package. These devices are active products with ROHS3 compliance and MSL-1 rating. The LME49726 variants deliver superior slew rate (3.7 V/µs) and gain bandwidth product (6.25 MHz), with significantly higher output current capability (350 mA per channel). Operating temperature range extends to 125°C (LME49726MY/NOPB) or 85°C (LME49726MYX/NOPB). These devices are suitable for audio and high-performance signal conditioning applications requiring enhanced bandwidth and output drive capability.
LMP2022MM/NOPB, LMP2022MME/NOPB, and LMP2022MMX/NOPB (Texas Instruments)
The LMP2022 series represents zero-drift dual operational amplifiers in 8-VSSOP package, all active products with ROHS3 compliance and MSL-1 rating. These devices feature exceptional input offset voltage (0.4 µV) and extended operating temperature range (-40°C to 125°C). The gain bandwidth product of 5 MHz and slew rate of 2.6 V/µs exceed the original MAX4075ADEUA+ specifications. Higher supply current (1.1 mA per channel) and output current (50 mA per channel) are trade-offs for precision performance. Packaging variants include Cut Tape (LMP2022MM/NOPB, LMP2022MME/NOPB) and Tape & Reel (LMP2022MMX/NOPB).
LMV358Q1MM/NOPB, LMV358Q1MMX/NOPB, LMV358Q3MM/NOPB, and LMV358Q3MMX/NOPB (Texas Instruments)
The LMV358 series comprises automotive-grade general-purpose dual operational amplifiers with rail-to-rail output in 8-VSSOP package. All variants are active products with ROHS3 compliance, MSL-1 rating, and AEC-Q100 automotive qualification. The LMV358Q1 variants support extended temperature range (-40°C to 125°C), while LMV358Q3 variants operate to -40°C to 85°C. Slew rate of 1 V/µs and gain bandwidth product of 1 MHz represent conservative performance specifications. Supply current of 210 µA per channel and output current of 160 mA per channel provide balanced power consumption and drive capability. Packaging includes both Tape & Reel (MMX suffix) and standard variants.
Frequently Asked Questions (FAQ)
Q1: Why is the MAX4075ADEUA+ classified as obsolete, and what does this mean for my design?
The MAX4075ADEUA+ is classified as obsolete by the manufacturer, indicating that production has been discontinued and future availability cannot be guaranteed. Designs currently using this component should transition to active substitute parts to ensure long-term supply chain continuity and support. The substitute parts listed maintain functional and electrical compatibility while offering active product status and extended manufacturer support.
Q2: Can I directly replace the MAX4075ADEUA+ with any of the listed substitute parts?
Direct replacement depends on application-specific requirements. All listed substitute parts share the following compatibility criteria: dual-circuit configuration, rail-to-rail output, surface-mount technology, 8-pin TSSOP/MSOP footprint, and 2.5V to 5.5V supply voltage overlap. However, performance characteristics such as slew rate, gain bandwidth product, input offset voltage, and supply current differ among substitutes. Verify that the substitute part's performance specifications meet your application requirements before implementation.
Q3: What are the key differences between the general-purpose (ISL28213FUZ-T7, LMV358 variants) and specialized (LME49726, LMP2022) substitute options?
General-purpose amplifiers (ISL28213FUZ-T7, LMV358 variants) provide balanced performance suitable for standard signal conditioning, filtering, and buffering applications. The LME49726 audio amplifiers deliver higher bandwidth (6.25 MHz) and output current (350 mA per channel), optimized for audio signal processing and high-impedance load driving. The LMP2022 zero-drift amplifiers offer exceptional input offset voltage (0.4 µV) and extended temperature range, essential for precision measurement and instrumentation applications where offset drift compensation is critical.
Q4: How do operating temperature ranges affect substitute part selection?
The original MAX4075ADEUA+ operates from -40°C to 70°C. Most substitute parts extend the upper temperature limit to 85°C or 125°C, providing enhanced thermal margin. The ISL28213FUZ-T7, LMP2022 series, and LMV358Q1 variants support -40°C to 125°C operation, offering the widest temperature coverage. If your application operates within the original -40°C to 70°C range, all listed substitutes are compatible. Applications requiring operation above 70°C should select substitutes with extended temperature ratings.
Q5: What is the significance of MSL (Moisture Sensitivity Level) ratings in the substitute parts?
MSL-1 rating (unlimited shelf life) indicates that the component has no moisture sensitivity restrictions and can be stored indefinitely without special handling. MSL-2 rating (1-year shelf life) requires controlled storage conditions and has a defined shelf life. The original MAX4075ADEUA+ carries MSL-1 rating. Most substitutes (LME49726, LMP2022, LMV358 variants) also feature MSL-1 rating. The ISL28213FUZ-T7 carries MSL-2 rating, requiring adherence to moisture control protocols during storage and handling.
Q6: Are there packaging format differences among the substitute parts, and do they affect PCB layout?
All substitute parts maintain the same 8-pin TSSOP/MSOP footprint (0.118", 3.00mm width) as the original MAX4075ADEUA+, ensuring direct PCB layout compatibility. Packaging format variations (Tape & Reel vs. Cut Tape) affect procurement and assembly processes but not electrical or mechanical compatibility. The LME49726 series uses 8-HVSSOP package, which maintains the same footprint dimensions as the standard 8-MSOP. Verify PCB footprint library definitions match the selected substitute part's package designation before layout finalization.
Q7: How do supply current specifications impact power budget calculations?
The original MAX4075ADEUA+ draws 37 µA per channel (74 µA total for dual circuits). Substitute parts show varying supply current: ISL28213FUZ-T7 (90 µA total), LMV358 variants (210 µA total), LMP2022 series (1.1 mA total), and LME49726 variants (700 µA total). Higher supply current increases power dissipation and thermal load. For battery-powered or low-power applications, the ISL28213FUZ-T7 or LMV358 variants offer minimal power overhead. For audio or high-performance applications, the LME49726 or LMP2022 series may be necessary despite higher power consumption.
Q8: What compliance certifications should I verify for my specific application?
All listed substitute parts are ROHS3 compliant and carry REACH Unaffected status, meeting standard environmental and hazardous substance regulations. The LMV358 series includes AEC-Q100 automotive qualification, required for automotive applications. If your design targets automotive, industrial, or medical markets, verify that the selected substitute part carries appropriate industry certifications (AEC-Q100 for automotive, IEC 60601 for medical devices, etc.) before final selection.
