Engineering Selection Recommendations
Tier 1: Direct Replacement (Recommended for Obsolescence Mitigation)
LMV822M/NOPB and LMV822MX/NOPB are the primary recommended substitutes. Both parts maintain active product status from Texas Instruments, the original manufacturer of LMV822D. Electrical specifications are functionally identical to the obsolete part, with marginal improvements in slew rate (2 V/µs vs. 1.9 V/µs) and gain bandwidth product (5.6 MHz vs. 5.5 MHz). Both parts are ROHS3 compliant and carry MSL Level 1 rating. The distinction between M/NOPB and MX/NOPB variants is packaging format: M/NOPB is supplied in tube packaging, while MX/NOPB is supplied in cut tape and Digi-Reel format. Selection between these variants depends on procurement and assembly requirements.
Tier 2: Automotive-Grade Alternatives (Extended Temperature Range)
LMV822IDT, LMV822AIDT, and LMV822IYDT are manufactured by STMicroelectronics under the LMV822 base product number. These parts maintain electrical compatibility with the original LMV822D while offering extended operating temperature range (-40°C to 125°C) and AEC-Q100 automotive qualification. Supply current is reduced to 300 µA per channel (vs. 500 µA), and output current per channel is increased to 70 mA (vs. 45 mA). Input bias current is slightly elevated at 60 nA. These parts are suitable for applications requiring automotive-grade reliability or extended temperature operation.
Tier 3: Enhanced Performance Alternatives
LMV722M/NOPB and LMV722MX/NOPB offer significantly improved performance specifications: slew rate of 5.25 V/µs (2.76× improvement), gain bandwidth product of 10 MHz (1.82× improvement), and output current of 52.6 mA per channel. These parts are qualified to AEC-Q100 automotive standards. However, input bias current increases to 260 nA and supply current increases to 2.01 mA per channel. These alternatives are suitable for applications where higher bandwidth and slew rate are beneficial and where increased supply current is acceptable.
AD8692ARZ-REEL from Analog Devices Inc. provides the highest performance envelope: 5 V/µs slew rate, 10 MHz gain bandwidth product, and 80 mA output current per channel. Input bias current is exceptionally low at 1 pA. Operating temperature range extends to 125°C. Supply current is 950 µA per channel. This part is suitable for precision applications requiring superior input bias characteristics and extended temperature operation.
Tier 4: Low-Power Alternative (Specialized Applications)
MCP617-I/SN and MCP617T-I/SN from Microchip Technology are CMOS amplifiers with significantly reduced power consumption (19 µA per channel). However, these parts do not meet minimum performance criteria for general-purpose substitution: slew rate is 0.08 V/µs and gain bandwidth product is 190 kHz. Output current per channel is limited to 17 mA. These parts are suitable only for applications where ultra-low power consumption is the primary design constraint and performance specifications can be relaxed accordingly.

Q3: Why would I select an automotive-grade LMV822 variant over the commercial-grade LMV822M/NOPB?
A: Automotive-grade variants (LMV822IDT, LMV822AIDT, LMV822IYDT) offer extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C) and AEC-Q100 qualification. These certifications are required for automotive applications and applications operating in high-temperature environments. Additionally, these variants feature reduced supply current (300 µA vs. 500 µA) and increased output current per channel (70 mA vs. 45 mA), which may benefit power-constrained designs.
Q4: When should I consider LMV722M/NOPB or LMV722MX/NOPB instead of LMV822 variants?
A: LMV722 variants provide 1.82× higher gain bandwidth product (10 MHz vs. 5.5 MHz) and 2.76× higher slew rate (5.25 V/µs vs. 1.9 V/µs). These improvements are beneficial for applications requiring higher-frequency signal processing or faster transient response. However, input bias current increases to 260 nA and supply current increases to 2.01 mA per channel. Evaluate whether the performance improvements justify the increased power consumption and input bias current for your specific application.
Q5: Is AD8692ARZ-REEL compatible with LMV822D designs?
A: AD8692ARZ-REEL maintains 8-SOIC package format and dual-channel configuration. However, it is not a direct equivalent. Key differences include: exceptionally low input bias current (1 pA vs. 40 nA), higher supply current (950 µA vs. 500 µA per channel), and extended operating temperature range (-40°C to 125°C). These characteristics make it suitable for precision applications where input bias current is critical. Verify that your circuit design can accommodate the higher supply current and that the extended temperature range is beneficial or neutral for your application.
Q6: Can MCP617-I/SN replace LMV822D?
A: MCP617-I/SN is not a suitable replacement for general-purpose applications. While it maintains 8-SOIC package format and dual-channel configuration, it fails to meet minimum performance criteria: slew rate is 0.08 V/µs (47× lower) and gain bandwidth product is 190 kHz (29× lower). Output current per channel is limited to 17 mA (vs. 45 mA). MCP617 is a CMOS amplifier optimized for ultra-low power consumption (19 µA per channel). It is suitable only for applications where power consumption is the primary design constraint and performance specifications can be significantly relaxed.

(3) If gain bandwidth product and slew rate must exceed 10 MHz and 5 V/µs respectively, select LMV722M/NOPB, LMV722MX/NOPB, or AD8692ARZ-REEL. (4) If supply current must be minimized below 100 µA per channel, select MCP617-I/SN or MCP617T-I/SN only if performance specifications can be relaxed. Verify all electrical parameters against your circuit design requirements before final selection.
Q9: Are there any package compatibility issues between LMV822D and its substitutes?
A: All recommended substitutes use 8-SOIC (0.154", 3.90mm width) surface-mount package, identical to LMV822D. Pin configuration and footprint are compatible. The primary consideration is packaging format for procurement and assembly: tube, cut tape, or tape & reel. Verify your assembly line equipment and supplier logistics support the selected packaging format.
