Substitute Part Grouping Explanation

Substitute parts for the LMV824DR are classified into two functional categories based on allowed electrical and mechanical parameters:

Category 1: Direct General-Purpose Amplifier Substitutes These parts maintain the general-purpose amplifier topology with four circuits, rail-to-rail output, and 14-SOIC packaging. Substitution is valid when the following parameters remain within acceptable ranges: slew rate ≥ 1.9 V/µs, gain bandwidth product ≥ 5.5 MHz, input bias current ≤ 40 nA (or lower), input offset voltage ≤ 1 mV (or lower), supply voltage span 2.5 V to 5.5 V, and operating temperature range -40°C to 85°C or extended. Parts in this category include LMV824M/NOPB, LMV824MX/NOPB, LMV824AIDT, LMV824DR2G, and LMV824IDT.

Category 2: Alternative Amplifier Architecture Substitutes These parts employ different amplifier topologies (CMOS architecture) while maintaining four circuits, rail-to-rail output, and 14-SOIC packaging. Substitution requires verification that the alternative architecture meets or exceeds the electrical performance envelope. Parts in this category include AD8604ARZ, MCP6284-E/SL, MCP6284T-E/SL, MCP619-I/SL, and MCP619T-I/SL.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

LMV824M/NOPB and LMV824MX/NOPB are the preferred direct substitutes for LMV824DR. Both are active products from Texas Instruments and National Semiconductor respectively, with identical electrical specifications to the original part. These substitutes feature marginally improved slew rate (2 V/µs vs. 1.9 V/µs) and gain bandwidth product (5.6 MHz vs. 5.5 MHz), ensuring full functional compatibility. Both maintain the same supply voltage range (2.5 V to 5.5 V), input bias current (40 nA), and output current per channel (45 mA). Packaging is 14-SOIC surface mount with ROHS3 compliance and MSL 1 rating.

Secondary Substitutes (Extended Temperature Range):

LMV824AIDT and LMV824IDT, both from STMicroelectronics, provide extended operating temperature range (-40°C to 125°C) compared to the original -40°C to 85°C specification. These parts maintain the same slew rate (1.9 V/µs) and gain bandwidth product (5.5 MHz). Input bias current is slightly elevated (60 nA vs. 40 nA), and input offset voltage differs (0.8 mV to 3.5 mV vs. 1 mV). Supply current is reduced to 0.3 mA per channel, and output current per channel is increased to 70 mA. Both carry AEC-Q100 automotive qualification. Selection of these parts is appropriate when extended temperature operation is required.

Alternative Architecture Substitutes:

AD8604ARZ from Analog Devices employs CMOS architecture with superior performance characteristics: slew rate of 6 V/µs, gain bandwidth product of 8.4 MHz, and extremely low input bias current (0.2 pA). This part is suitable for applications requiring higher speed and lower input current. Operating temperature extends to 125°C. MCP6284-E/SL and MCP6284T-E/SL from Microchip Technology offer general-purpose amplifier topology with slew rate of 2.5 V/µs and extended temperature range to 125°C, though gain bandwidth product is slightly lower (5 MHz). MCP619-I/SL and MCP619T-I/SL employ ultra-low-power CMOS architecture with supply current of only 19 µA per channel, suitable for battery-powered applications, but with significantly reduced slew rate (0.08 V/µs) and gain bandwidth product (190 kHz).

Compliance and Certification:

All recommended substitutes maintain ROHS3 compliance and MSL 1 rating. LMV824AIDT and LMV824IDT carry AEC-Q100 automotive qualification. Selection should prioritize active product status and compliance requirements for the target application.

Frequently Asked Questions (FAQ)

Q1: Can LMV824M/NOPB directly replace LMV824DR without circuit modification?

A: Yes. LMV824M/NOPB is a direct functional equivalent with identical electrical specifications within the allowed parameter ranges. Both parts feature 14-SOIC packaging, four independent circuits, rail-to-rail output, and operate across 2.5 V to 5.5 V supply voltage. The substitute exhibits marginally improved performance (slew rate 2 V/µs vs. 1.9 V/µs, GBW 5.6 MHz vs. 5.5 MHz), ensuring full compatibility. No circuit redesign is required.

Q2: What is the primary difference between LMV824AIDT and LMV824IDT?

A: Both parts are from STMicroelectronics with identical electrical performance and 14-SOIC packaging. The primary difference is input offset voltage specification: LMV824AIDT specifies 0.8 mV maximum, while LMV824IDT specifies 3.5 mV maximum. Both carry AEC-Q100 automotive qualification and extended operating temperature range (-40°C to 125°C). Selection depends on input offset voltage tolerance requirements for the application.

Q3: Why is AD8604ARZ listed as a substitute despite different amplifier type?

A: AD8604ARZ employs CMOS architecture rather than general-purpose topology, but maintains the four-circuit, rail-to-rail, 14-SOIC configuration. It exceeds the electrical performance envelope of LMV824DR with superior slew rate (6 V/µs vs. 1.9 V/µs), gain bandwidth product (8.4 MHz vs. 5.5 MHz), and input bias current (0.2 pA vs. 40 nA). Substitution is valid for applications where higher performance is acceptable or beneficial. Extended temperature range (-40°C to 125°C) is an additional advantage.

Q4: Can MCP619-I/SL replace LMV824DR in high-speed applications?

A: No. MCP619-I/SL is not suitable for high-speed applications. Although it maintains four circuits and 14-SOIC packaging, its slew rate (0.08 V/µs) and gain bandwidth product (190 kHz) are significantly lower than LMV824DR (1.9 V/µs and 5.5 MHz respectively). MCP619-I/SL is optimized for ultra-low-power operation (19 µA supply current) and is appropriate only for low-frequency, battery-powered applications.

Q5: What packaging options are available for LMV824 substitutes?

A: All listed substitutes are available in 14-SOIC (0.154", 3.90mm Width) surface-mount package, matching the original LMV824DR. Packaging variants differ by tape format: some are supplied in Tube, others in Cut Tape (CT) & Digi-Reel®, and others in Tape & Reel (TR). Selection of packaging format depends on production volume and assembly equipment compatibility. Electrical specifications remain identical across all packaging formats for a given part number.

Q6: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. Moisture Sensitivity Level (MSL) is uniformly rated as 1 (Unlimited) for most substitutes, with the exception of LMV824DR2G which is rated MSL 3 (168 Hours). MSL rating affects storage and handling requirements prior to assembly. Parts with MSL 1 require no special moisture control, while MSL 3 parts require controlled storage conditions.

Q7: Which substitute offers the best thermal performance?

A: LMV824AIDT and LMV824IDT from STMicroelectronics, along with AD8604ARZ from Analog Devices and MCP6284 variants from Microchip Technology, all support extended operating temperature range of -40°C to 125°C, compared to the original LMV824DR specification of -40°C to 85°C. Selection among these depends on other electrical parameter requirements and application-specific thermal constraints.

Q8: What is the inventory status of recommended substitutes?

A: LMV824M/NOPB has 1,360 units in stock. LMV824MX/NOPB has 25,400 units. LMV824AIDT has 18,108 units. LMV824DR2G has 1,300 units. LMV824IDT has 20,755 units. AD8604ARZ has 9,097 units. MCP6284-E/SL has 35,635 units. MCP6284T-E/SL has 12,600 units. MCP619-I/SL has 2,402 units. MCP619T-I/SL has 1,961 units. Inventory levels are subject to change; verification with suppliers is recommended for production planning.
