Product details
Overview
LMV824DG4 from Texas Instruments is a quad, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 5.5 V) and 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 sensor interfaces and battery-powered data acquisition systems.
For engineers reviewing the LMV824DG4 datasheet, LMV824DG4 pinout, LMV824DG4 application, or LMV824DG4 equivalent, key selection considerations include its SOIC-14 package, –40°C to 85°C operating range, rail-to-rail output swing down to 100 mV from rails (at 2 kΩ load), input offset voltage ≤4 mV, and absence of crossover distortion in audio and instrumentation front-ends.
Technical Context
The LMV824DG4 integrates four independent high-speed op-amps sharing a common 2.5–5.5 V single-supply rail. Each amplifier features a CMOS input stage with 30 nA typical input bias current and supports input common-mode voltage down to ground (–0.2 V at 25°C), enabling direct interfacing with ADCs and microcontroller analog inputs.
Its internal architecture eliminates crossover distortion and provides stable unity-gain operation with ≥64.2° phase margin at 5 V and 600 Ω load. Amplifier-to-amplifier isolation exceeds 135 dB, making it suitable for multi-channel signal paths where crosstalk must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 5.5 V - enables direct operation from Li-ion, 3.3 V, or 5 V system rails without regulation. |
| Gain Bandwidth Product | 5.5 MHz typ at 5 V - supports closed-loop gains up to ~55 at 100 kHz with stable response. |
| Slew Rate | 1.9 V/μs typ at 5 V - ensures <1% THD for 10 kHz sine waves at 2 VPP output swing. |
| Input Offset Voltage | ≤4 mV max over –40°C to 85°C - reduces DC error in precision sensor amplification stages. |
| Rail-to-Rail Output | Swings within 100 mV of VCC+ and GND at 2 kΩ load - maximizes dynamic range in single-supply systems. |
| Supply Current | 1 mA typ (all four amps) at 5 V - allows integration into ultra-low-power designs with <4 mW total quiescent power. |
| Input Common-Mode Range | Extends to GND (–0.2 V min) - permits direct sensing of signals referenced to ground or negative references. |
Pinout & Package
LMV824DG4 is housed in a 14-pin SOIC (D) package with standard 1.27 mm pitch, 8.65 mm × 3.91 mm footprint, and exposed pad not present. Pin numbering follows TI's top-view convention with Pin 1 marked by a dot or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Amplified output of first op-amp; drives loads up to 20 mA sourcing/sinking. |
| 2 | Channel 1 Inverting Input | Inverting node for feedback configuration; high impedance (>1012 Ω) minimizes loading on source. |
| 3 | Channel 1 Non-Inverting Input | Reference input for differential or non-inverting gain stages; accepts signals down to GND. |
| 4 | Positive Supply (VCC+) | Single-supply rail connection; decoupling capacitor required near pin for stability. |

| 6 | Channel 2 Inverting Input | Feedback node for second op-amp; shares no internal coupling with adjacent channels. |
| 7 | Channel 2 Output | Dedicated output for second channel; maintains >135 dB isolation from Channel 1. |
| 8 | GND / VCC− | Ground reference and negative rail terminal; must be connected to system ground plane. |
| 9 | Channel 3 Non-Inverting Input | Third amplifier input; identical electrical specs to Pins 5 and 11. |
| 10 | Channel 3 Inverting Input | Third amplifier feedback node; layout symmetry recommended for matched performance. |
| 11 | Channel 3 Output | Output of third op-amp; supports same drive capability and rail-swing as other outputs. |
| 12 | Channel 4 Non-Inverting Input | Fourth amplifier input; fully independent with no shared biasing or routing. |
| 13 | Channel 4 Inverting Input | Feedback node for fourth op-amp; validated for unity-gain stable operation. |
| 14 | Channel 4 Output | Final output; completes quad-channel set with consistent AC/DC performance across all units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824DR | Same SOIC-14 package, identical electrical specs, but tape-and-reel packaging (2500 pcs) vs. tube (90 pcs) for LMV824DG4. | No functional difference; suited for automated SMT assembly rather than prototyping or low-volume production. | Select LMV824DR for high-volume manufacturing; LMV824DG4 remains valid for small-batch builds or legacy procurement. |
| TLV2464CDR | Higher 6.4 MHz GBW, lower 0.65 mV VIO, but 1.2 mA ICC and narrower 2.7–6 V supply range. | Better DC precision and speed, but less compatible with 2.5 V logic rails and higher power budget. | Choose TLV2464CDR when sub-millivolt offset and >100 kHz bandwidth are mandatory; retain LMV824DG4 for cost-sensitive 2.5 V–5.5 V systems. |
Compared with LMV824DR, LMV824DG4 offers identical performance in a tube-packaged form factor ideal for evaluation and pilot runs; versus TLV2464CDR, LMV824DG4 trades minor offset and bandwidth for broader supply flexibility and lower quiescent power in battery-operated designs.

FAQ
What is the operating temperature range for LMV824DG4?
The LMV824DG4 is characterized for operation from –40°C to +85°C. This range is specified in the official Texas Instruments datasheet (SLOS434I, Rev. July 2006) and applies to all electrical parameters unless otherwise noted. It does not support the extended –40°C to +125°C range offered by the LMV824I variants (e.g., LMV824IDR).
Does LMV824DG4 support true rail-to-rail input?
No, LMV824DG4 does not support rail-to-rail input. Its input common-mode voltage range extends to GND (–0.2 V minimum at 25°C) but only up to VCC+ – 0.3 V maximum (4.2 V at 5 V supply). The device provides rail-to-rail *output* swing - within 100 mV of both supply rails under 2 kΩ load - but input stage headroom limitations require design allowance near VCC+.
What is the maximum output current capability of LMV824DG4?
LMV824DG4 can source or sink up to 20 mA per amplifier (typical at 25°C, VCC+ = 5 V), with guaranteed minimum of 15 mA over –40°C to +85°C. Performance degrades slightly at lower supply voltages: at 2.7 V, output current drops to ~12 mA sourcing/sinking. Load matching and thermal derating must be considered in multi-channel simultaneous drive scenarios.
Is LMV824DG4 pin-compatible with other quad op-amps like LM324 or TLC274?
No, LMV824DG4 is not pin-compatible with LM324 or TLC274. While all three use SOIC-14 packages, their pinouts differ significantly: LM324 places all inverting inputs on odd-numbered pins (1, 5, 9, 13) and non-inverting on evens (2, 6, 10, 12), whereas LMV824DG4 uses Pins 2/3, 5/6, 9/10, and 12/13 for inverting/non-inverting pairs per channel. PCB redesign is required for substitution.
Why is LMV824DG4 marked "Not Recommended for New Designs"?
LMV824DG4 is marked "Not Recommended for New Designs" per TI's official documentation due to newer alternatives (e.g., TLV9064, OPA4991) offering superior specs - including lower offset, wider bandwidth, lower noise, and enhanced ESD robustness - while maintaining pin compatibility in some cases. However, LMV824DG4 remains fully qualified, in-stock, and supported for legacy design refreshes and long-lifecycle industrial programs.
