LMV822IDE4 Equivalent & Substitute Parts
Part Overview
The LMV822IDE4 is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual-channel configuration in 8-SOIC surface-mount packaging. This device is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. The LMV822IDE4 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. Substitute parts must maintain functional compatibility through matching electrical characteristics and identical package geometry.

Engineering Selection Recommendations
Tier 1 - Direct Replacements (Recommended Primary Choice):
LMV822M/NOPB and LMV822MX/NOPB are the preferred substitutes for LMV822IDE4. Both are manufactured by Texas Instruments under the same LMV822 base product number, ensuring electrical and mechanical compatibility. These parts maintain identical input bias current (40 nA), input offset voltage (1 mV), and output current specifications (45 mA). Operating temperature range is reduced to -40°C to 85°C compared to the original -40°C to 125°C specification. Both parts carry active product status and ROHS3 compliance. LMV822MX/NOPB offers higher inventory availability (30,163 units) in Cut Tape & Digi-Reel packaging, while LMV822M/NOPB is available in Tube packaging (2,155 units).
Tier 2 - Functional Equivalents with Enhanced Performance:
LMV822IDT and LMV822AIDT, manufactured by STMicroelectronics, provide functional equivalence with automotive-grade qualification (AEC-Q100). Both maintain the 1.9V/µs slew rate and 5.5 MHz gain bandwidth product. LMV822AIDT offers superior input offset voltage (0.8 mV vs. 1.0 mV) and higher output current capability (70 mA vs. 45 mA). Operating temperature range extends to -40°C to 125°C, matching the original device. LMV822IDT is available with 17,900 units in inventory, while LMV822AIDT provides 25,200 units.
Tier 3 - Performance-Enhanced Alternatives:
LMV722M/NOPB and LMV722MX/NOPB offer significantly enhanced performance with 10 MHz gain bandwidth product and 5.25V/µs slew rate. These parts exceed the original specifications but introduce higher input bias current (260 nA). Automotive qualification (AEC-Q100) is included. LMV722MX/NOPB provides substantial inventory (35,400 units).
MAX4326ESA+ provides extended supply voltage range (2.4V to 6.5V) with comparable slew rate (2.0V/µs) and lower input offset voltage (0.7 mV). Operating temperature is limited to -40°C to 85°C.
ADA4692-2ARZ-RL offers extremely low input bias current (0.5 pA) and low input offset voltage (500 µV) but with reduced slew rate (1.3V/µs) and gain bandwidth product (3.6 MHz). Supply voltage range is 2.7V to 5.0V.
Tier 4 - Not Recommended:
MCP617-I/SN and MCP617T-I/SN are CMOS amplifiers with significantly reduced performance specifications (0.08V/µs slew rate, 190 kHz gain bandwidth product, 17 mA output current). These parts do not meet the electrical requirements of the LMV822IDE4 and are unsuitable for direct substitution.
Frequently Asked Questions (FAQ)
Q: Can LMV822M/NOPB directly replace LMV822IDE4 in existing designs?
A: Yes. LMV822M/NOPB is electrically and mechanically compatible with LMV822IDE4. Both are dual-channel general-purpose amplifiers in 8-SOIC packaging with identical input bias current (40 nA), input offset voltage (1 mV), and output current (45 mA). The primary difference is operating temperature range: LMV822M/NOPB operates to 85°C versus 125°C for the original. If your application requires operation above 85°C, use LMV822IDT or LMV822AIDT instead.
Q: What is the difference between LMV822MX/NOPB and LMV822M/NOPB?
A: Both parts are electrically identical. The difference is packaging: LMV822MX/NOPB is supplied in Cut Tape & Digi-Reel format with higher inventory (30,163 units), while LMV822M/NOPB is supplied in Tube packaging (2,155 units). Select based on your procurement and assembly requirements.
Q: Why do LMV722M/NOPB and LMV722MX/NOPB have higher input bias current?
A: LMV722 series devices feature enhanced performance specifications including 10 MHz gain bandwidth product and 5.25V/µs slew rate compared to LMV822 series (5.5 MHz and 1.9V/µs). This performance enhancement results in higher input bias current (260 nA vs. 40 nA). Use LMV722 variants only if your application requires the higher bandwidth and slew rate.
Q: Are STMicroelectronics LMV822IDT and LMV822AIDT suitable replacements?
A: Yes. Both STMicroelectronics parts maintain the 1.9V/µs slew rate and 5.5 MHz gain bandwidth product of the original LMV822IDE4. LMV822AIDT offers improved input offset voltage (0.8 mV) and higher output current (70 mA). Both include automotive-grade qualification (AEC-Q100) and operate across the full -40°C to 125°C temperature range. These are preferred for automotive and extended-temperature applications.
Q: Can MCP617-I/SN or MCP617T-I/SN replace LMV822IDE4?
A: No. MCP617 series are CMOS amplifiers with fundamentally different performance characteristics: 0.08V/µs slew rate (vs. 1.9V/µs), 190 kHz gain bandwidth product (vs. 5.5 MHz), and 17 mA output current (vs. 45 mA). These specifications do not meet the requirements of LMV822IDE4 and are unsuitable for direct substitution.
Q: What packaging options are available for LMV822 substitutes?
A: All substitute parts are supplied in 8-SOIC (0.154", 3.90mm width) surface-mount packaging, maintaining mechanical compatibility with LMV822IDE4. Packaging formats vary: LMV822M/NOPB (Tube), LMV822MX/NOPB (Cut Tape & Digi-Reel), LMV822IDT (Cut Tape & Digi-Reel), LMV822AIDT (Tape & Reel), and MAX4326ESA+ (Tube). Select based on your assembly process requirements.
Q: Does supply voltage range affect substitution compatibility?
A: Yes. LMV822IDE4 operates from 2.5V to 5.5V. Most substitutes maintain this range. However, ADA4692-2ARZ-RL operates from 2.7V to 5.0V (narrower range), and MAX4326ESA+ operates from 2.4V to 6.5V (wider range). Verify your application's supply voltage requirements before selection.
Q: What is the significance of RoHS3 compliance and MSL rating?
A: All listed substitute parts carry RoHS3 compliance and MSL Level 1 (Unlimited moisture sensitivity), matching the original LMV822IDE4. These certifications ensure environmental compliance and indicate that the parts can be stored indefinitely without moisture-related degradation, simplifying inventory management and supply chain logistics.
