LMV324IDRE4 Equivalent & Substitute Parts
Part Overview
The LMV324IDRE4 is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-SOIC surface-mount package. This device is designed for rail-to-rail output applications with a supply voltage range of 2.7 V to 5.5 V and operates across the industrial temperature range of -40°C to 125°C.
The LMV324IDRE4 has been discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives. Substitute parts must maintain compatibility with the original electrical specifications, mechanical packaging, and environmental operating conditions to ensure seamless integration into existing designs.

Engineering Selection Recommendations
Tier 1: Direct Substitutes (Highest Compatibility)
LMV324M/NOPB and LMV324MX/NOPB are direct substitutes manufactured by Texas Instruments under the same base product number (LMV324). Both parts maintain identical electrical specifications to the LMV324IDRE4, including slew rate, gain bandwidth product, input bias current, and input offset voltage. The primary difference is packaging format (Tube and Cut Tape/Digi-Reel respectively) and enhanced output current capability (160 mA versus 40 mA per channel). Both are ROHS3 compliant with MSL 1 rating and active product status. These parts are recommended for direct replacement without circuit redesign.
Tier 2: Functional Equivalents (Full Specification Coverage)
ISL28413FBZ and ISL28413FBZ-T7 (Renesas Electronics) meet all mandatory compatibility criteria. These parts provide superior input offset voltage (0.5 mV versus 1.7 mV), lower input bias current (3 pA versus 15 nA), and higher gain bandwidth product (2 MHz versus 1 MHz). Operating temperature range extends to -40°C to 125°C. Supply voltage range is 1.8 V to 5.5 V, providing broader low-voltage capability. Both are ROHS3 compliant with active status. MSL rating is 2 (1 Year), requiring appropriate moisture control during storage and handling.
AD8544ARZ-REEL and AD8544WARZ-R7 (Analog Devices Inc.) provide full temperature range coverage (-40°C to 125°C) with 1 MHz gain bandwidth product. Input bias current is 4 pA and input offset voltage is 1 mV, both superior to the original specification. Output current per channel is 30 mA, meeting minimum requirements. Supply current is 45 µA per four channels, significantly lower than the original 410 µA. Both are ROHS3 compliant with MSL 1 rating and active status.
Tier 3: Limited Compatibility (Application-Dependent)
LMV324IDR (UMW) operates at reduced temperature range (-25°C to 85°C), excluding the full industrial specification. Supply voltage minimum is 2.1 V, and output current per channel is 25 mA, below the original 40 mA specification. This part is suitable only for applications not requiring full -40°C to 125°C operation.
LPV324M/NOPB and LPV324MX/NOPB (Texas Instruments) feature significantly reduced slew rate (0.1 V/µs versus 1 V/µs) and gain bandwidth product (152 kHz versus 1 MHz). Operating temperature maximum is 85°C, excluding the upper industrial range. These parts are suitable only for low-frequency, low-speed applications.
BU7487F-E2 (Rohm Semiconductor) is a CMOS amplifier with substantially different electrical characteristics, including 10 V/µs slew rate and 10 MHz gain bandwidth product. Supply current is 6 mA per four channels, significantly higher than the original 410 µA. Operating temperature maximum is 105°C, below the original 125°C specification. This part is suitable only for high-speed applications where the original performance is insufficient.
Frequently Asked Questions (FAQ)
Q: Can LMV324M/NOPB directly replace LMV324IDRE4 without circuit modification?
A: Yes. LMV324M/NOPB is manufactured by Texas Instruments under the same base product number and maintains identical electrical specifications for slew rate, gain bandwidth product, input bias current, and input offset voltage. The 14-SOIC package dimensions are identical. The primary difference is packaging format (Tube versus Tape & Reel) and higher output current capability (160 mA versus 40 mA per channel), which provides enhanced performance margin. No circuit redesign is required.
Q: What is the difference between ISL28413FBZ and ISL28413FBZ-T7?
A: Both parts are manufactured by Renesas Electronics with identical electrical specifications. The difference is packaging format: ISL28413FBZ is supplied in Tube packaging, while ISL28413FBZ-T7 is supplied in Tape & Reel (TR) format. Electrical performance, temperature range, and compliance certifications are identical. Selection depends on assembly process requirements and inventory management preferences.
Q: Why does BU7487F-E2 have higher supply current than the original LMV324IDRE4?
A: BU7487F-E2 is a CMOS amplifier architecture with fundamentally different power consumption characteristics. The 6 mA supply current (per four channels) reflects the CMOS design approach, which trades higher quiescent current for superior slew rate (10 V/µs) and gain bandwidth product (10 MHz). This part is suitable only for applications requiring high-speed performance where the original 1 V/µs slew rate is insufficient.
Q: Can LPV324M/NOPB be used in applications requiring 1 MHz gain bandwidth product?
A: No. LPV324M/NOPB has a gain bandwidth product of 152 kHz, which is insufficient for applications designed around the original 1 MHz specification. Additionally, the slew rate is reduced to 0.1 V/µs. This part is suitable only for low-frequency, low-speed signal conditioning applications. For full performance compatibility, use LMV324M/NOPB, ISL28413FBZ, or AD8544ARZ-REEL.
Q: What is the significance of MSL rating differences between substitute parts?
A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. MSL 2 (as specified for ISL28413FBZ and ISL28413FBZ-T7) requires moisture control during storage and handling, with a maximum shelf life of 1 year under specified conditions. For high-volume manufacturing environments with established moisture control procedures, MSL 2 parts present no practical limitation. For applications with extended storage periods or limited moisture control infrastructure, MSL 1 parts (LMV324M/NOPB, AD8544ARZ-REEL) are preferred.
Q: Is the UMW LMV324IDR a suitable substitute for the discontinued LMV324IDRE4?
A: LMV324IDR is not recommended as a primary substitute. While it maintains the 14-SOIC package and 1 MHz gain bandwidth product, the operating temperature range is limited to -25°C to 85°C, excluding the upper industrial specification of 125°C. Output current per channel is 25 mA, below the original 40 mA specification. This part is suitable only for applications operating within the reduced temperature range and lower output current requirements.
Q: What are the key parameters that determine substitution compatibility?
A: Substitution compatibility is determined by: (1) four independent amplifier circuits, (2) rail-to-rail output configuration, (3) 14-SOIC surface-mount package, (4) supply voltage range overlap (minimum 2.7 V to 5.5 V), (5) operating temperature range coverage (-40°C to 125°C), (6) ROHS3 compliance, and (7) MSL 1 or MSL 2 rating. Secondary performance parameters include slew rate (≥1 V/µs), gain bandwidth product (≥1 MHz), input bias current (≤15 nA), input offset voltage (≤1.7 mV), and output current per channel (≥40 mA).
Q: Are there any compliance or certification differences between substitute parts?
A: All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the original LMV324IDRE4 certification status. ECCN classification is EAR99 for all parts. HTSUS code is 8542.33.0001 for all parts. The primary compliance difference is MSL rating: LMV324M/NOPB, LMV324MX/NOPB, AD8544ARZ-REEL, and AD8544WARZ-R7 are MSL 1, while ISL28413FBZ and ISL28413FBZ-T7 are MSL 2. This difference affects moisture control requirements during storage and handling but does not impact electrical performance or regulatory compliance.
