Product details
Overview
LMV824IDRG4 from Texas Instruments is a quad, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 5.5 V), low-power applications. It delivers 5.5 MHz gain bandwidth, 1.9 V/μs slew rate, and 1 mA typical supply current at 5 V - enabling precision signal conditioning in space-constrained portable electronics such as battery-powered sensors and medical monitoring front-ends.
For engineers reviewing the LMV824IDRG4 datasheet, LMV824IDRG4 pinout, LMV824IDRG4 application, or LMV824IDRG4 equivalent, key selection criteria include its –40°C to 125°C operating range, rail-to-rail output swing (4.85 V high / 0.17 V low at 5 V, RL = 600 Ω), input offset voltage ≤5.5 mV over temperature, and SOIC-14 package compatibility with industrial-grade thermal performance (θJA = 97°C/W).
Technical Context
The LMV824IDRG4 integrates four independent amplifiers sharing a common 2.5–5.5 V single-supply rail, with input common-mode range extending to ground and output swing within 170 mV of VCC+ and 100 mV of GND under 600 Ω load. Its internal architecture eliminates crossover distortion and supports stable unity-gain operation with ≥64.2° phase margin at 5 V and 600 Ω load.
Designed for cost-sensitive, low-noise analog signal paths, it features 42 nV/√Hz input voltage noise and 135 dB amplifier-to-amplifier isolation - critical for multi-channel sensor interfaces where crosstalk and power efficiency directly impact measurement fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 5.5 V - enables direct integration into 3.3 V and 5 V systems without level-shifting. |
| Gain Bandwidth | 5.5 MHz typ at 5 V - supports closed-loop bandwidths up to ~500 kHz with moderate gain (AV = 10) in sensor amplifier stages. |
| Slew Rate | 1.9 V/μs typ at 5 V - sufficient for 10-bit ADC driving and audio preamp signals up to ~100 kHz full-scale. |
| Input Offset Voltage | ≤5.5 mV over –40°C to 125°C - ensures <0.1% error in 5 V-span bridge sensor outputs without trimming. |
| Output Swing | 0.17 V to 4.85 V at 5 V, RL = 600 Ω - delivers >96% rail utilization for maximizing dynamic range into ADCs or comparators. |
| Supply Current | 1.3 mA max over temperature (all four amps) - allows continuous operation in always-on battery nodes with <10 μA standby budget per channel. |
| Common-Mode Range | –0.3 V to 4.3 V at 5 V - accepts inputs below ground (e.g., transducer biasing) and up to near VCC. |
Pinout & Package
LMV824IDRG4 is housed in a 14-pin SOIC (D) package with standard 1.27 mm pitch, 8.65 mm × 3.91 mm footprint, and θJA = 97°C/W. Pin mapping follows TI's quad op-amp convention with dual power rails and individual I/O per amplifier.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Drives external load or next-stage input; rail-to-rail capable with 20 mA sink/source capability. |
| 2 | Channel 1 Inverting Input | Accepts feedback or differential signal; high-impedance node (IIB ≤150 nA) minimizes loading on source. |
| 3 | Channel 1 Non-Inverting Input | Reference or signal input; common-mode range includes ground for single-supply sensor interfacing. |
| 4 | Negative Supply / Ground | Return path for all four amplifiers; must be low-impedance to maintain PSRR >70 dB. |
| 5 | Channel 2 Non-Inverting Input | Independent input for second channel; electrically isolated from other channels (135 dB crosstalk rejection). |
| 6 | Channel 2 Inverting Input | Feedback node for Channel 2; matched to Pin 2 for consistent loop compensation across channels. |
| 7 | Channel 2 Output | Second independent output; identical AC/DC specs to Pin 1 for matched multi-channel designs. |
| 8 | Positive Supply | Single 2.5–5.5 V rail powering all four amplifiers; decoupling required within 1 cm for stability. |
| 9 | Channel 3 Non-Inverting Input | Third channel input; layout symmetry with Pins 3 and 5 reduces board-level mismatch in multi-sensor arrays. |
| 10 | Channel 3 Inverting Input | Third channel feedback node; shares same electrical characteristics as Pins 2 and 6. |
| 11 | Channel 3 Output | Third output; validated for simultaneous operation with other channels without thermal derating. |
| 12 | Channel 4 Inverting Input | Fourth channel feedback input; pinout symmetry simplifies PCB routing for 4-channel instrumentation. |
| 13 | Channel 4 Non-Inverting Input | Fourth channel signal input; supports DC-coupled configurations due to ground-referenced input range. |
| 14 | Channel 4 Output | Final output; fully characterized for drive strength and settling time matching other channels. |
Key Features
| Feature | Design Value |
|---|---|

| Rail-to-Rail Output | Delivers usable output swing within 170 mV of VCC+ and 100 mV of GND at 600 Ω, maximizing ADC input range. |
| Low 1/f Noise Corner | Input voltage noise flat at 42 nV/√Hz from 1 kHz - critical for low-frequency sensor amplification (e.g., strain gauges). |
| High Amplifier Isolation | 135 dB channel-to-channel isolation prevents signal coupling in multi-channel data acquisition systems. |
| Extended Temperature Range | Specified from –40°C to 125°C - suitable for under-hood automotive or industrial motor control feedback loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824DR | Same silicon, but rated for –40°C to 85°C; lower max operating temperature and no 125°C qualification. | Suitable only for commercial/industrial environments without extended thermal stress. | Select LMV824DR only if ambient temperature remains ≤85°C and cost is primary constraint. |
| TLV2464CDR | Higher supply current (1.4 mA typ), lower GBW (6.4 MHz), and wider input offset (2 mV max at 25°C vs. 5.5 mV over temp for LMV824IDRG4). | Better DC precision at room temperature but less robust over full automotive temperature range. | Choose TLV2464CDR when room-temperature accuracy dominates; avoid for wide-temp deployments. |
Compared with LMV824DR and TLV2464CDR, LMV824IDRG4 uniquely combines 125°C operation, 1.3 mA max supply current, and 5.5 MHz bandwidth - making it the only option qualified for under-hood or high-reliability industrial use without thermal derating or performance trade-offs.

FAQ
What is the maximum operating temperature specification for LMV824IDRG4?
The LMV824IDRG4 is characterized for operation from –40°C to 125°C, making it suitable for under-hood automotive applications and industrial environments with elevated ambient temperatures. This extended range is confirmed in the "Recommended Operating Conditions" table of the official TI datasheet SLOS434I, and distinguishes it from the commercial-grade LMV824DR variant.
Does LMV824IDRG4 support true rail-to-rail input operation?
No, LMV824IDRG4 features rail-to-rail *output* swing but not rail-to-rail input. Its input common-mode voltage range extends from –0.3 V to 4.3 V at 5 V supply (i.e., 300 mV below ground and 700 mV below VCC+), allowing ground-referenced inputs but not full rail coverage. This is explicitly defined in the "Electrical Characteristics" tables for VICR under both 2.7 V and 5 V conditions.
What is the typical supply current consumption of LMV824IDRG4 at 3.3 V?
At 3.3 V supply and 25°C, LMV824IDRG4 draws approximately 0.85 mA typical (all four amplifiers active), interpolated from the 2.7 V (0.72 mA typ) and 5 V (1.0 mA typ) ICC values in the datasheet. The actual value remains within the 1.3 mA maximum limit across –40°C to 125°C, ensuring predictable power budgeting in 3.3 V embedded systems.
Can LMV824IDRG4 drive a 600 Ω load while maintaining rail-to-rail output swing?
Yes - LMV824IDRG4 is specified to deliver 0.17 V to 4.85 V output swing at 5 V supply into a 600 Ω load, representing >96% of the full rail. This performance is verified in the "5-V Electrical Characteristics" table (VO parameter, RL = 600 Ω) and enables direct interfacing with legacy 5 V ADCs and comparators without external level-shifting circuitry.
Is LMV824IDRG4 pin-compatible with other quad op-amps in SOIC-14 packages?
LMV824IDRG4 uses TI's standard quad op-amp pinout (per Figure 1 in SLOS434I), matching industry conventions for SOIC-14 quad amplifiers like the TLV2464 and MCP6004. However, absolute pin compatibility requires verification of power pin placement (Pins 4/GND and 8/VCC), channel ordering, and output polarity - all of which align for LMV824IDRG4, enabling drop-in replacement where electrical specs meet system requirements.
