MAX4482ASA+ Equivalent & Substitute Parts Reference

Part Overview

The MAX4482ASA+ is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, featuring dual circuits in an 8-SOIC surface-mount package. This device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs and ongoing production requirements. The MAX4482ASA+ provides rail-to-rail output capability with low-power operation, making it suitable for battery-powered and space-constrained applications. Due to its obsolete status, active substitute parts with comparable electrical and mechanical characteristics are required to maintain design continuity and ensure component availability.

The following parts maintain identical mechanical compatibility and are suitable for direct PCB substitution:

LMV722ID / LMV722IDR (Texas Instruments, Active): Provide enhanced performance with 5.25 V/µs slew rate and 10 MHz gain-bandwidth product. Operating temperature range extends to 105°C. Higher supply current (1.81 mA) and output current (52.6 mA) support higher-load applications. REACH compliant.
LMV822AIDT / LMV822IDT (STMicroelectronics, Active): Maintain full -40°C to 125°C operating range matching the original specification. LMV822AIDT carries AEC-Q100 automotive qualification. Slew rate of 1.9 V/µs and 5.5 MHz gain-bandwidth product provide moderate performance enhancement. LMV822IDT exhibits higher input offset voltage (3.5 mV) compared to LMV822AIDT (0.8 mV).
LMV822M/NOPB / LMV822MX/NOPB (Texas Instruments, Active): Offer 2 V/µs slew rate and 5.6 MHz gain-bandwidth product. Operating temperature limited to -40°C to 85°C. Lower input bias current (40 nA) and input offset voltage (1 mV) provide improved precision. REACH compliant.
LPV358M/NOPB / LPV358MX (Texas Instruments, Active/Last Time Buy): Deliver ultra-low supply current (15 µA per channel) and minimal input bias current (2 nA), optimized for battery-powered applications. Slew rate (0.1 V/µs) and gain-bandwidth product (152 kHz) closely match the original MAX4482ASA+. Operating temperature range -40°C to 85°C. LPV358MX is designated Last Time Buy status.

Frequently Asked Questions (FAQ)

Q1: Can LMV722ID directly replace MAX4482ASA+ on existing PCBs?

A: Yes. LMV722ID maintains identical 8-SOIC package dimensions (0.154", 3.90mm width) and pinout compatibility. No PCB layout modification is required. However, the significantly higher supply current (1.81 mA versus 50 µA) and output current (52.6 mA versus 17 mA) must be evaluated against power budget constraints.

Q2: Which substitute offers the closest electrical match to MAX4482ASA+?

A: LPV358M/NOPB and LPV358MX provide the closest electrical characteristics, with slew rate (0.1 V/µs) and gain-bandwidth product (152 kHz) nearly identical to the original. Supply current (15 µA) is significantly lower. Operating temperature range is limited to -40°C to 85°C.

Q3: What is the difference between LMV822AIDT and LMV822IDT?

A: Both parts are manufactured by STMicroelectronics with identical electrical performance except for input offset voltage: LMV822AIDT specifies 0.8 mV maximum, while LMV822IDT specifies 3.5 mV maximum. LMV822AIDT carries AEC-Q100 automotive qualification. Both maintain -40°C to 125°C operating range.

Q4: Are LMV822M/NOPB and LMV822MX/NOPB interchangeable?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications. The difference is packaging format: LMV822M/NOPB is supplied in Tube, while LMV822MX/NOPB is supplied in Cut Tape & Digi-Reel®. Operating temperature range is -40°C to 85°C for both.

Q5: Why is LMR932F-GE2 listed as a substitute if the package differs?

A: LMR932F-GE2 is included as a functional alternative for applications where PCB layout modification is acceptable. The 8-SOP package (0.173", 4.40mm width) differs from the original 8-SOIC (0.154", 3.90mm width). This part offers enhanced performance but requires design re-evaluation.

Q6: Which substitute is recommended for automotive applications?

A: LMV822AIDT (STMicroelectronics) is qualified to AEC-Q100 automotive standard and maintains the full -40°C to 125°C operating temperature range. This part is suitable for automotive-grade designs requiring component reliability certification.

Q7: What is the significance of "Last Time Buy" status for LPV358MX?

A: Last Time Buy status indicates the manufacturer has announced end-of-life for this part. Existing inventory may be available, but future procurement is not guaranteed. For new designs requiring long-term component availability, LPV358M/NOPB (Active status) is preferred.

Q8: Can I use LMV722IDR instead of LMV722ID?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications. LMV722IDR is supplied in Cut Tape & Digi-Reel® packaging with higher inventory (25,300 pcs), while LMV722ID is supplied in Tube with lower inventory (1,401 pcs). Electrical performance is equivalent.

Q9: What are the key compliance certifications for these substitutes?

A: All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level (MSL) 1 (Unlimited). LMV822AIDT and LMV822IDT carry REACH Unaffected status. LMV722ID, LMV722IDR, LMV822M/NOPB, LMV822MX/NOPB, LPV358M/NOPB, and LPV358MX all carry REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001.

Q10: How do I select between multiple LMV822 variants?

A: Selection depends on application requirements: (1) LMV822AIDT for automotive applications requiring AEC-Q100 qualification; (2) LMV822IDT for general industrial use with lower cost; (3) LMV822M/NOPB or LMV822MX/NOPB for Texas Instruments ecosystem preference. All maintain -40°C to 125°C range except TI variants (-40°C to 85°C).
