LMV822MMX Equivalent & Substitute Parts Reference

Part Overview

The LMV822MMX is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in an 8-VSSOP surface-mount package. This device delivers rail-to-rail output capability with a 5.6 MHz gain-bandwidth product and operates across a 2.5 V to 5.5 V supply range, making it suitable for low-voltage analog signal processing applications.

The LMV822MMX is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements. Substitute parts must maintain functional compatibility within the specified electrical and mechanical parameters while considering packaging, compliance status, and operational characteristics.

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute):

The LMV822MMX/NOPB (National Semiconductor) is the direct equivalent of the LMV822MMX. It maintains identical electrical specifications, package format, and functional characteristics. This part is currently in active product status with 17,559 units in stock. The primary advantage is zero design modification required. The part qualifies for automotive applications under AEC-Q100 standard, providing enhanced reliability for demanding environments.

Active General-Purpose Alternatives (LMV822 Base Series):

The LMV822AIST, LMV822IST, and LMV822IYST (all STMicroelectronics) represent the same LMV822 base product line with active status and extended temperature range (-40°C to 125°C). These parts use the 8-MiniSO package instead of 8-VSSOP, requiring PCB layout modification. All three variants carry AEC-Q100 automotive qualification and RoHS3 compliance. Electrical performance is nearly identical with minor variations in input offset voltage (800 µV to 3.5 mV versus 1 mV). Supply current is reduced to 300 µA per channel, offering improved power efficiency. Output current capability increases to 70 mA per channel.

Higher-Performance General-Purpose Alternatives:

The AD8692ARMZ-R7, AD8692ARMZ-REEL, and AD8692WARMZ-REEL (Analog Devices Inc.) offer enhanced performance specifications: 5 V/µs slew rate, 10 MHz gain-bandwidth product, and 1 pA input bias current. These parts operate across 2.7 V to 6 V supply range with extended temperature capability to 125°C. All variants are RoHS3 compliant. The 8-MSOP package requires PCB layout modification. Higher supply current (950 µA per channel) and output current (80 mA per channel) must be evaluated against power budget constraints. These alternatives are suitable for applications requiring superior signal fidelity and faster transient response.

CMOS Topology Alternatives:

The FAN4852IMU8X (onsemi) and LMR342FVJ-GE2 (Rohm Semiconductor) employ CMOS amplifier architecture. The FAN4852IMU8X is obsolete but offers 6.1 V/µs slew rate and 9 MHz gain-bandwidth product with extremely low input bias current (0.1 pA). The LMR342FVJ-GE2 is active with the lowest supply current (200 µA) and highest output current (113 mA) in the comparison set, but features reduced slew rate (1 V/µs) and gain-bandwidth product (2 MHz). CMOS alternatives are appropriate only when input bias current minimization is a critical design requirement.

Specialized High-Speed Alternative:

The LTC6269HMS8E-10#PBF (Analog Devices Inc., J-FET topology) is fundamentally different from the LMV822MMX, featuring 1500 V/µs slew rate and 4 GHz gain-bandwidth product. This part is suitable only for high-frequency signal processing applications and is not recommended as a general substitute due to significantly higher supply current (16.5 mA per channel) and different operational characteristics.

Compliance and Supply Chain Considerations:

For new designs or production requiring RoHS3 compliance, the LMV822AIST, LMV822IST, LMV822IYST, AD8692 variants, LMR342FVJ-GE2, and LTC6269HMS8E-10#PBF are compliant. The original LMV822MMX is RoHS non-compliant. For automotive applications, LMV822MMX/NOPB, LMV822AIST, LMV822IST, and LMV822IYST carry AEC-Q100 qualification. Current inventory levels range from 1,156 to 50,650 units across all alternatives, supporting various production volumes.

Frequently Asked Questions (FAQ)

Q1: Can I directly replace LMV822MMX with LMV822MMX/NOPB without any design changes?

A: Yes. The LMV822MMX/NOPB is the direct equivalent with identical electrical specifications and 8-VSSOP package format. No PCB layout or schematic modifications are required. This is the recommended substitute for maintaining design continuity.

Q2: What is the primary difference between LMV822MMX and the STMicroelectronics LMV822 variants (AIST, IST, IYST)?

A: The STMicroelectronics variants use the 8-MiniSO package instead of 8-VSSOP, requiring PCB layout modification. Electrically, they offer extended temperature range (-40°C to 125°C), reduced supply current (300 µA per channel), and AEC-Q100 automotive qualification. Input offset voltage tolerance is slightly relaxed (up to 3.5 mV). All three variants are in active production status.

Q3: Are the AD8692 variants from Analog Devices direct replacements?

A: No. The AD8692 variants use the 8-MSOP package, requiring PCB layout redesign. They offer superior electrical performance (5 V/µs slew rate, 10 MHz gain-bandwidth product, 1 pA input bias current) but consume higher supply current (950 µA per channel). These are functional alternatives for applications requiring enhanced performance, not direct pin-compatible replacements.

Q4: Which substitute part offers the lowest power consumption?

A: The LMR342FVJ-GE2 (Rohm Semiconductor) provides the lowest supply current at 200 µA per channel. However, this CMOS device has reduced slew rate (1 V/µs) and gain-bandwidth product (2 MHz) compared to the LMV822MMX. Power reduction comes with performance trade-offs.

Q5: Can I use the LTC6269HMS8E-10#PBF as a substitute for general-purpose applications?

A: No. The LTC6269HMS8E-10#PBF is a J-FET amplifier with fundamentally different characteristics: 1500 V/µs slew rate, 4 GHz gain-bandwidth product, and 16.5 mA supply current per channel. This device is designed for high-frequency signal processing and is not suitable for general-purpose low-voltage applications. Using it would result in unnecessary cost and complexity.

Q6: What package format changes are required when switching to STMicroelectronics LMV822 variants?

A: The LMV822AIST, LMV822IST, and LMV822IYST use 8-MiniSO package instead of the original 8-VSSOP. While both are 8-pin surface-mount packages with 0.118" (3.00 mm) width, the pin pitch and footprint differ. PCB layout modification is required, including updated component footprint, trace routing, and via placement. Verify mechanical clearance and thermal management considerations.

Q7: Are all substitute parts RoHS3 compliant?

A: No. The original LMV822MMX is RoHS non-compliant. The LMV822MMX/NOPB (National Semiconductor) status is not specified in the provided data. The STMicroelectronics LMV822 variants (AIST, IST, IYST), all Analog Devices AD8692 variants, LMR342FVJ-GE2, and LTC6269HMS8E-10#PBF are RoHS3 compliant. For new designs requiring environmental compliance, select from the RoHS3-compliant alternatives.

Q8: Which substitute parts carry automotive qualification?

A: The LMV822MMX/NOPB (National Semiconductor), LMV822AIST, LMV822IST, and LMV822IYST (STMicroelectronics) all carry AEC-Q100 automotive qualification. These parts are suitable for automotive and industrial applications requiring enhanced reliability and qualification documentation.

Q9: What is the inventory status for each substitute part?

A: Inventory levels vary significantly: LMV822MMX (50,650 units), LMV822MMX/NOPB (17,559 units), LMV822AIST (27,200 units), LMV822IST (8,520 units), LMV822IYST (12,200 units), AD8692ARMZ-R7 (6,100 units), AD8692ARMZ-REEL (1,800 units), AD8692WARMZ-REEL (12,950 units), FAN4852IMU8X (45,200 units), LMR342FVJ-GE2 (9,371 units), and LTC6269HMS8E-10#PBF (1,156 units). Verify current availability with your supplier for production planning.

Q10: Can I use CMOS alternatives (FAN4852IMU8X or LMR342FVJ-GE2) in place of the general-purpose LMV822MMX?

A: CMOS alternatives are functionally compatible for dual-channel rail-to-rail amplification but introduce different operational characteristics. The FAN4852IMU8X offers higher slew rate (6.1 V/µs) and gain-bandwidth product (9 MHz) with extremely low input bias current (0.1 pA). The LMR342FVJ-GE2 has reduced slew rate (1 V/µs) and gain-bandwidth product (2 MHz) but lowest supply current (200 µA). Use CMOS alternatives only when their specific performance characteristics align with application requirements, not as general substitutes.
