Substitute Part Grouping Explanation

Substitute parts for the LMV824IPW are grouped into two functional categories based on electrical and mechanical compatibility:

Category 1: Direct General-Purpose Amplifier Substitutes These parts maintain the general-purpose amplifier topology with slew rates and gain-bandwidth products comparable to the LMV824IPW. Substitution is based on matching: four-circuit configuration, rail-to-rail output, 14-TSSOP package, supply voltage range (2.5 V to 5.5 V minimum), and operating temperature range (-40°C to 125°C or -40°C to 85°C). Parts in this category include LMV824MT/NOPB, LMV824MTX/NOPB, LMV824AIPT, LMV824DTBR2G, LMV824IPT, and MCP6284-E/ST.

Category 2: CMOS Amplifier Substitutes These parts employ CMOS technology with significantly lower input bias current and supply current. While slew rate and gain-bandwidth product differ substantially, these devices maintain four-circuit configuration, rail-to-rail output, 14-TSSOP package, and overlapping supply voltage ranges. Parts in this category include AD8619WARUZ-R7, AD8619WARUZ-RL, MCP619-I/ST, and MCP619T-I/ST. CMOS substitutes are suitable only when application requirements permit lower bandwidth and slew rate performance.

Engineering Selection Recommendations

For Direct Replacement (General-Purpose Category)

LMV824MT/NOPB and LMV824MTX/NOPB are active Texas Instruments products with electrical characteristics nearly identical to the LMV824IPW. Both maintain slew rate of 2 V/µs, gain-bandwidth product of 5.6 MHz, and identical supply current specifications. The primary difference is operating temperature range (-40°C to 85°C versus -40°C to 125°C). These parts are suitable for applications where the reduced upper temperature limit is acceptable. Both are ROHS3 compliant and carry unlimited moisture sensitivity rating.

LMV824AIPT and LMV824IPT, manufactured by STMicroelectronics, preserve the full -40°C to 125°C operating range and maintain slew rate and gain-bandwidth product matching the LMV824IPW. These parts carry AEC-Q100 automotive qualification. Supply current per channel is specified as 300 µA (versus 1 mA total), and output current per channel is 70 mA (versus 45 mA). These devices are suitable for automotive-grade applications requiring extended temperature operation.

LMV824DTBR2G, manufactured by onsemi, provides active product status with slew rate of 2 V/µs and gain-bandwidth product of 5.6 MHz. Operating temperature range is -40°C to 85°C. Input bias current is elevated at 119 nA. This part is suitable for applications where the reduced temperature range is acceptable and elevated input bias current does not compromise circuit performance.

MCP6284-E/ST, manufactured by Microchip Technology, maintains the full -40°C to 125°C operating temperature range and general-purpose amplifier topology. Slew rate is 2.5 V/µs and gain-bandwidth product is 5 MHz. Supply current is significantly lower at 450 µA total (versus 1 mA), and output current per channel is 25 mA (versus 45 mA). This part is suitable for power-sensitive applications where reduced output current capability is acceptable.

For CMOS Substitution (CMOS Category)

AD8619WARUZ-R7 and AD8619WARUZ-RL are active Analog Devices CMOS amplifiers with full -40°C to 125°C operating range. Input bias current is extremely low at 0.2 pA, and supply current is 38 µA. However, slew rate is 0.1 V/µs and gain-bandwidth product is 400 kHz, representing significant reductions from the LMV824IPW. Output current per channel is 80 mA. These parts are suitable only for low-frequency, low-power applications where bandwidth and slew rate requirements are substantially lower than the original design.

MCP619-I/ST and MCP619T-I/ST, manufactured by Microchip Technology, are CMOS amplifiers with operating temperature range of -40°C to 85°C. Input bias current is 5 nA, and supply current is 19 µA. Slew rate is 0.08 V/µs and gain-bandwidth product is 190 kHz. Output current per channel is 17 mA. These parts are suitable only for applications with minimal bandwidth and slew rate requirements and reduced operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can LMV824MT/NOPB directly replace LMV824IPW in all applications?

A: LMV824MT/NOPB is electrically compatible with LMV824IPW for applications operating within -40°C to 85°C. The slew rate (2 V/µs) and gain-bandwidth product (5.6 MHz) are marginally superior. If your application requires operation above 85°C, this substitute is not suitable. Verify your circuit's maximum operating temperature requirement before selection.

Q: What is the key difference between LMV824AIPT and LMV824IPT?

A: Both parts are manufactured by STMicroelectronics with identical electrical specifications and full -40°C to 125°C operating range. LMV824AIPT is specified for automotive applications with AEC-Q100 qualification. LMV824IPT carries the same automotive qualification. The primary distinction is packaging designation. Both are suitable for automotive-grade designs requiring extended temperature operation.

Q: Why do CMOS substitutes (AD8619, MCP619) have such different performance?

A: CMOS amplifiers employ a different semiconductor technology optimized for extremely low input bias current and supply current consumption. This optimization results in reduced slew rate and gain-bandwidth product. AD8619 and MCP619 series are suitable only for applications where bandwidth and slew rate requirements are substantially lower than general-purpose designs. Do not substitute CMOS parts into circuits designed for 5+ MHz bandwidth without circuit redesign and testing.

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 4.40 mm width specification. Pin-to-pin compatibility is maintained. PCB layout and footprint remain unchanged. However, verify pinout assignment in device datasheets, as some manufacturers may assign different functions to specific pins.

Q: What does "Product Status: Active" mean for substitute selection?

A: Active status indicates the manufacturer currently produces and supports the part. Obsolete status (LMV824IPW) indicates the manufacturer has discontinued production and may not provide technical support or guarantee future availability. Selection of active substitute parts ensures long-term supply chain reliability and manufacturer support for design questions.

Q: Can I use MCP6284-E/ST if my circuit requires 45 mA output current per channel?

A: No. MCP6284-E/ST specifies maximum output current of 25 mA per channel, compared to 45 mA for LMV824IPW. If your circuit design requires 45 mA output current, MCP6284-E/ST will not function correctly. Verify your circuit's actual output current requirement before substitution. If output current exceeds 25 mA, select LMV824MT/NOPB, LMV824AIPT, or LMV824DTBR2G instead.

Q: What is the significance of "ROHS3 Compliant" and "Moisture Sensitivity Level 1"?

A: ROHS3 compliance indicates the part contains no restricted hazardous substances per European Union regulations. Moisture Sensitivity Level 1 (unlimited) indicates the part requires no special moisture-control handling during storage, transport, or assembly. All listed substitute parts carry identical compliance ratings, ensuring regulatory and manufacturing process compatibility with the original LMV824IPW design.
