LMV822MX Equivalent & Substitute Parts Reference

Part Overview

The LMV822MX is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in an 8-SOIC surface-mount package. This device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The LMV822MX operates across a 2.5V to 5.5V supply range with rail-to-rail output capability, making it suitable for low-voltage analog signal processing applications.

Equivalent and substitute parts are necessary when the LMV822MX reaches end-of-life status or when inventory constraints require alternative sourcing. Substitute devices must maintain compatibility across electrical performance parameters, mechanical packaging, and operational specifications to ensure direct circuit board replacement without design modification.

Substitute Part Grouping Explanation

Substitute parts for the LMV822MX are classified into two primary categories based on electrical and mechanical compatibility:

Category 1: Direct Equivalents (Identical Base Product) Parts sharing the LMV822 base product number with identical electrical specifications and 8-SOIC packaging. These include LMV822MX/NOPB (Texas Instruments, Active status), LMV822AIDT (STMicroelectronics, Automotive-grade), and LMV822IDT (STMicroelectronics, Automotive-grade). These devices maintain the same slew rate (2V/µs or 1.9V/µs), gain bandwidth product (5.5-5.6 MHz), supply voltage range (2.5V-5.5V), and output current specifications (45-70 mA per channel).

Category 2: Functional Equivalents (Enhanced Performance) Parts with superior electrical performance characteristics while maintaining 8-SOIC packaging and rail-to-rail output. These include AD8692ARZ variants (Analog Devices), MAX4326ESA+ (Maxim Integrated), and LMR822FJ-GE2 (Rohm Semiconductor). These devices offer higher slew rates (5V/µs), increased gain bandwidth products (10 MHz), lower input bias currents (1 pA), and extended temperature ranges (-40°C to 125°C).

Substitution Criteria: The following parameters determine valid substitution:

Package type: 8-SOIC surface mount (0.154", 3.90mm width)
Number of circuits: 2 (dual amplifier)

Engineering Selection Recommendations

Primary Recommendation: LMV822MX/NOPB This Texas Instruments part maintains identical electrical and mechanical specifications to the LMV822MX while offering Active product status. It is the direct equivalent with the same packaging (Cut Tape & Digi-Reel), supply voltage range (2.5V-5.5V), and performance characteristics. Current inventory of 30,163 units ensures availability. This part is suitable for direct substitution without circuit modification.

Secondary Recommendation: LMV822AIDT or LMV822IDT Both STMicroelectronics variants provide Active status with automotive-grade qualification (AEC-Q100). These parts maintain the 8-SOIC package and 2.5V-5.5V supply range. The extended operating temperature range (-40°C to 125°C) provides additional thermal margin. Slew rate (1.9V/µs) and gain bandwidth product (5.5 MHz) remain within acceptable tolerance of the original specification. Higher output current capability (70 mA per channel) offers improved drive capability. These parts are suitable for applications requiring automotive qualification or extended temperature operation.

Alternative Recommendation: AD8692ARZ Variants Analog Devices AD8692ARZ, AD8692ARZ-REEL, and AD8692ARZ-REEL7 offer enhanced performance with higher slew rate (5V/µs), increased gain bandwidth product (10 MHz), and superior input characteristics (1 pA input bias current, 400 µV input offset). Extended temperature range (-40°C to 125°C) and higher output current (80 mA per channel) provide performance headroom. These parts are suitable for applications where improved dynamic response and lower noise performance are beneficial, though they consume higher supply current (950 µA vs. 500 µA).

Not Recommended: MAX4402ASA+ and MAX4482ASA+ MAX4402ASA+ exhibits significantly reduced gain bandwidth product (800 kHz) and slew rate (1 µs/µs), making it unsuitable for applications requiring the 5.6 MHz bandwidth of the LMV822MX. MAX4482ASA+ is classified as Obsolete with extremely limited performance (140 kHz bandwidth, 0.08V/µs slew rate) and should not be selected for new designs.

Frequently Asked Questions (FAQ)

Q1: Can LMV822MX/NOPB be used as a direct replacement for LMV822MX? Yes. LMV822MX/NOPB is the direct equivalent with identical electrical specifications, 8-SOIC packaging, and supply voltage range. The primary difference is product status (Active vs. Last Time Buy) and packaging format (Cut Tape & Digi-Reel vs. original packaging). No circuit modification is required.

Q2: What is the key difference between Category 1 and Category 2 substitutes? Category 1 substitutes (LMV822MX/NOPB, LMV822AIDT, LMV822IDT) maintain the original electrical performance specifications with identical or near-identical slew rate and gain bandwidth product. Category 2 substitutes (AD8692ARZ variants) offer enhanced performance with higher slew rates and bandwidth, suitable for applications requiring improved dynamic response. Category 2 parts consume more supply current and may require circuit evaluation.

Q3: Are automotive-grade variants (LMV822AIDT, LMV822IDT) suitable for non-automotive applications? Yes. Automotive-grade parts with AEC-Q100 qualification meet or exceed commercial-grade specifications. These parts are suitable for any application within their specified operating parameters. The automotive qualification provides additional reliability assurance and extended temperature range (-40°C to 125°C vs. -40°C to 85°C).

Q4: What is the impact of different packaging formats (Tube vs. Cut Tape & Digi-Reel)? Packaging format affects handling and storage but does not impact electrical performance or circuit compatibility. Cut Tape & Digi-Reel packaging is suitable for automated assembly processes. Tube packaging is suitable for manual assembly or lower-volume applications. The 8-SOIC package dimensions (0.154", 3.90mm width) remain identical across all variants.

Q5: Can MAX4402ASA+ or MAX4482ASA+ replace LMV822MX in existing designs? No. MAX4402ASA+ has insufficient gain bandwidth product (800 kHz vs. 5.6 MHz) and slew rate (1V/µs vs. 2V/µs) for applications designed around LMV822MX specifications. MAX4482ASA+ is obsolete with severely limited performance (140 kHz bandwidth). These parts are not suitable substitutes and would require complete circuit redesign.

Q6: What supply voltage range must substitute parts support? All substitute parts must support the minimum 2.5V and maximum 5.5V supply voltage range of the LMV822MX. Parts with extended ranges (such as AD8692ARZ at 2.7V-6V) are compatible but not required. Verify that the substitute part's supply range encompasses the application's operating voltage.

Q7: How does input bias current affect substitution decisions? Input bias current affects circuit impedance and DC offset characteristics. The LMV822MX specifies 40 nA input bias current. Substitutes with higher input bias (60 nA for STMicroelectronics variants) or significantly lower input bias (1 pA for AD8692ARZ) may require circuit evaluation if the application is sensitive to input impedance or DC offset. For most general-purpose applications, variations within this range are acceptable.

Q8: Is RoHS3 compliance maintained across all substitute parts? Yes. All recommended substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, matching the environmental and regulatory requirements of the LMV822MX.
