LMV824IDR Equivalent & Substitute Parts

Part Overview

The LMV824IDR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-SOIC surface-mount package. This device delivers rail-to-rail output capability with a gain-bandwidth product of 5.5 MHz and operates across a 2.5 V to 5.5 V supply range. The LMV824IDR is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. Substitute parts must maintain functional compatibility across critical electrical parameters including supply voltage range, output type, circuit count, and thermal operating range.

Engineering Selection Recommendations

Direct Equivalents (Preferred for Pin-Compatible Replacement):

The LMV824AIDT and LMV824IDT from STMicroelectronics are direct functional equivalents with active product status and extended operating temperature range (-40°C to 125°C), matching the original LMV824IDR specification. Both devices maintain identical supply voltage range (2.5 V to 5.5 V), four-circuit configuration, and rail-to-rail output. The LMV824AIDT offers superior output current capability (70 mA per channel versus 45 mA) and lower input offset voltage (0.8 mV), while the LMV824IDT provides identical slew rate and gain-bandwidth product to the original part. Both are AEC-Q100 qualified and RoHS3 compliant with MSL 1 rating.

Texas Instruments LMV824 Variants (Same Manufacturer):

The LMV824M/NOPB and LMV824MX/NOPB maintain identical electrical characteristics to the original LMV824IDR with marginally improved slew rate (2 V/µs) and gain-bandwidth product (5.6 MHz). Operating temperature is limited to -40°C to 85°C. These parts are suitable for applications not requiring extended temperature operation above 85°C. The LMV824MX/NOPB includes AEC-Q100 automotive qualification.

onsemi LMV824DR2G (Alternative Source):

The LMV824DR2G provides active product status with comparable electrical performance (2 V/µs slew rate, 5.6 MHz GBW). Minimum supply voltage is 2.7 V (versus 2.5 V for the original), and operating temperature is -40°C to 85°C. Input bias current is elevated at 119 nA. This part is suitable for applications with supply voltages ≥2.7 V and non-extended-temperature requirements.

Microchip MCP6284 Series (Extended Temperature, Low Input Bias):

The MCP6284-E/SL and MCP6284T-E/SL offer extended operating temperature (-40°C to 125°C), extremely low input bias current (1 pA), and lower minimum supply voltage (2.2 V). Slew rate is improved to 2.5 V/µs. Output current per channel is reduced to 25 mA. These parts are suitable for precision applications requiring low input bias and extended temperature operation, provided output current requirements do not exceed 25 mA per channel.

Microchip MCP6484 Series (Ultra-Low Power, Extended Temperature):

The MCP6484-E/SL delivers extended operating temperature (-40°C to 125°C) with ultra-low input bias current (1 pA) and reduced supply current (240 µA total). Output current is limited to 12 mA per channel. This part is suitable for battery-powered or ultra-low-power applications where output current requirements are modest.

Microchip MCP619 Series (CMOS, Ultra-Low Power):

The MCP619-I/SL and MCP619T-I/SL are CMOS amplifiers with extremely low input bias current (5 nA) and supply current (19 µA total). Slew rate and gain-bandwidth product are significantly reduced (0.08 V/µs, 190 kHz). These parts are suitable only for low-frequency, ultra-low-power applications where bandwidth and slew rate requirements are minimal.

Selection Criteria Summary:

Extended temperature (-40°C to 125°C) required: LMV824AIDT, LMV824IDT, MCP6284-E/SL, MCP6284T-E/SL, or MCP6484-E/SL

Frequently Asked Questions (FAQ)

Q1: Can the LMV824M/NOPB directly replace the LMV824IDR in all applications?

The LMV824M/NOPB is electrically compatible with the LMV824IDR across all critical parameters (supply voltage, output type, circuit count, package). However, the operating temperature range is limited to -40°C to 85°C versus -40°C to 125°C for the original. Substitution is valid only for applications operating within the -40°C to 85°C range. Packaging differs (Tube versus unspecified for the original).

Q2: What is the difference between LMV824AIDT and LMV824IDT?

Both are STMicroelectronics parts with identical electrical performance and extended temperature range (-40°C to 125°C). The LMV824AIDT offers superior output current (70 mA per channel versus 45 mA) and lower input offset voltage (0.8 mV versus 3.5 mV). The LMV824IDT maintains closer input offset voltage specification to the original LMV824IDR (3.5 mV versus 1 mV). Selection depends on output current and offset voltage requirements.

Q3: Why do MCP6284 and MCP6484 have such low input bias current (1 pA)?

These Microchip parts employ JFET input stages, which inherently exhibit extremely low input bias current compared to bipolar input stages used in the LMV824 series. This characteristic is beneficial for high-impedance signal sources but does not affect general-purpose amplifier functionality.

Q4: Is the MCP619 series suitable as a substitute for the LMV824IDR?

The MCP619 series is not recommended as a direct substitute. While it maintains the four-circuit, rail-to-rail, 14-SOIC configuration and supply voltage compatibility, the slew rate (0.08 V/µs) and gain-bandwidth product (190 kHz) are approximately 20 to 30 times lower than the LMV824IDR. Substitution is valid only for low-frequency applications (DC to ~100 kHz) where bandwidth is not critical.

Q5: What packaging options are available for LMV824 substitutes?

Substitute parts are available in three packaging formats: Tube (standard reel packaging), Cut Tape (CT) & Digi-Reel (individual component tape), and Tape & Reel (TR) for automated assembly. The original LMV824IDR packaging is unspecified. Selection should match production requirements: Tube for manual assembly, CT/Digi-Reel for small-quantity pick-and-place, and TR for high-volume automated assembly.

Q6: Are all substitute parts RoHS3 compliant?

All substitute parts listed are RoHS3 compliant. Moisture sensitivity levels vary: LMV824 series and MCP6284/MCP6484 series are MSL 1 (unlimited shelf life), while LMV824DR2G is MSL 3 (168-hour maximum floor life after moisture exposure). MSL 3 parts require controlled storage and handling procedures.

Q7: Which substitute offers the best balance of performance and availability?

The LMV824AIDT from STMicroelectronics provides optimal balance: active product status, extended temperature range (-40°C to 125°C), superior output current (70 mA), AEC-Q100 qualification, RoHS3 compliance, and high inventory availability (18,108 units). This part is recommended as the primary substitute for the obsolete LMV824IDR.

Q8: Can I use MCP6284 or MCP6484 in place of LMV824IDR if output current is not a limiting factor?

Yes, with qualification. Both MCP6284 and MCP6484 series maintain supply voltage compatibility (2.2 V to 5.5 V), extended temperature operation (-40°C to 125°C), four-circuit configuration, and rail-to-rail output. Output current per channel is reduced (25 mA for MCP6284, 12 mA for MCP6484 versus 45 mA for LMV824IDR). Substitution is valid only if application output current requirements do not exceed these limits.

Q9: What is the significance of the "M" designation in LMV824M/NOPB?

The "M" suffix indicates a specific temperature and performance grade within the LMV824 family. The LMV824M/NOPB is rated for -40°C to 85°C operation (commercial temperature range) versus the extended -40°C to 125°C range of the original LMV824IDR. The "/NOPB" suffix indicates "No Plumbum" (lead-free) RoHS compliance.

Q10: Are there any supply voltage compatibility issues between the LMV824IDR and its substitutes?

The LMV824IDR operates from 2.5 V to 5.5 V. Most substitutes maintain this range. Exceptions: MCP6284/MCP6484 series support 2.2 V minimum (lower), MCP619 series supports 2.3 V minimum (lower), and LMV824DR2G requires 2.7 V minimum (higher). Verify application supply voltage against substitute specifications before selection.
