Engineering Selection Recommendations
Tier 1 - Direct LMV824 Series Substitutes (Highest Compatibility):
LMV824AIPT and LMV824IPT from STMicroelectronics are direct active equivalents sharing the LMV824 base product number. Both maintain identical electrical performance specifications (1.9V/µs slew rate, 5.5 MHz gain bandwidth product) and operate across the full -40°C to 125°C temperature range. LMV824AIPT carries AEC-Q100 automotive qualification. LMV824DTBR2G from onsemi provides equivalent performance with marginally improved slew rate (2.0V/µs) and gain bandwidth product (5.6 MHz), though operating temperature range is limited to -40°C to 85°C.
Tier 2 - Microchip MCP6284 Series (General Purpose Alternative):
MCP6284T-E/ST and MCP6284-E/ST from Microchip Technology are active general purpose amplifiers meeting all primary substitution criteria. These devices feature enhanced slew rate (2.5V/µs) and maintain 5.0 MHz gain bandwidth product across the full -40°C to 125°C operating range. Output current per channel is reduced to 25 mA compared to the LMV824 series 45 mA specification.
Tier 3 - Microchip MCP6484 Series (Low Power Alternative):
MCP6484-E/ST provides the lowest supply current consumption (0.6 mA total) among general purpose substitutes, with 2.7V/µs slew rate and 4.0 MHz gain bandwidth product. Output current per channel is limited to 12 mA. This device is suitable for power-constrained applications within the -40°C to 125°C operating range.
Tier 4 - Low Bandwidth CMOS Alternatives:
MCP619T-I/ST and MCP619-I/ST from Microchip Technology, and AD8619WARUZ-R7 and AD8619WARUZ-RL from Analog Devices Inc., are CMOS amplifiers with significantly reduced bandwidth (190 kHz and 400 kHz respectively) and slew rate (0.08V/µs and 0.1V/µs respectively). These devices are suitable only for applications not requiring the 5.5 MHz bandwidth of the original LMV824IPWRG4. MCP619 variants operate to -40°C to 85°C; AD8619 variants operate to -40°C to 125°C.
All recommended substitutes maintain RoHS3 compliance and appropriate moisture sensitivity ratings for surface mount assembly.
Frequently Asked Questions (FAQ)
Q: Can LMV824AIPT directly replace LMV824IPWRG4 in existing designs?
A: Yes. LMV824AIPT is a direct active equivalent from STMicroelectronics sharing the LMV824 base product number. It maintains identical slew rate (1.9V/µs), gain bandwidth product (5.5 MHz), supply voltage range (2.5V to 5.5V), and operating temperature range (-40°C to 125°C). The 14-TSSOP package is identical. Pin-for-pin compatibility is confirmed.
Q: What is the difference between LMV824AIPT and LMV824IPT?
A: Both are STMicroelectronics LMV824 variants with identical electrical specifications. LMV824AIPT carries AEC-Q100 automotive qualification and is packaged in Tape & Reel format. LMV824IPT is qualified for automotive applications and supplied in Cut Tape & Digi-Reel format. Electrical performance is equivalent.
Q: Why do MCP619 and AD8619 devices have lower bandwidth than the LMV824?
A: MCP619 and AD8619 are CMOS amplifier architectures optimized for ultra-low input bias current and supply current consumption. These design choices result in reduced gain bandwidth product (190 kHz to 400 kHz) compared to the LMV824 general purpose design (5.5 MHz). These devices are suitable only for applications not requiring high-frequency signal processing.
Q: Is the 14-TSSOP package identical across all substitute parts?
A: Yes. All substitute parts listed use the 14-TSSOP package with 0.173" width and 4.40mm body width. Physical footprint and PCB layout compatibility is confirmed across all alternatives.
Q: What is the maximum operating temperature for LMV824DTBR2G?
A: LMV824DTBR2G from onsemi operates to a maximum of 85°C, compared to 125°C for the original LMV824IPWRG4 and most other substitutes. This limitation must be evaluated for applications requiring extended temperature operation.
Q: Can MCP6484-E/ST replace LMV824IPWRG4 in high output current applications?
A: No. MCP6484-E/ST provides only 12 mA output current per channel, compared to 45 mA for the LMV824IPWRG4. Applications requiring output currents exceeding 12 mA must use LMV824 series variants, MCP6284 series (25 mA), or AD8619 series (80 mA).
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed carry RoHS3 compliance certification. Moisture sensitivity levels range from MSL 1 (Unlimited) to MSL 3 (168 Hours), consistent with surface mount assembly requirements.
Q: What is the primary advantage of AD8619WARUZ variants over LMV824 substitutes?
A: AD8619WARUZ devices feature extremely low input bias current (0.2 pA) and input offset voltage (400 µV), with higher output current capability (80 mA per channel). However, gain bandwidth product is significantly reduced (400 kHz). These devices are suitable for precision instrumentation applications not requiring high-frequency response.
Q: Can packaging format (Tape & Reel vs. Cut Tape) affect substitution decisions?
A: Packaging format affects supply chain and assembly logistics but does not impact electrical compatibility. LMV824AIPT (Tape & Reel) and LMV824IPT (Cut Tape & Digi-Reel) are electrically identical. Selection should be based on production volume and assembly equipment compatibility.
