Product details
Overview
LMV824DR 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 sensor interfaces and battery-powered data acquisition systems.
For engineers reviewing the LMV824DR datasheet, LMV824DR pinout, LMV824DR application, or LMV824DR equivalent, this page provides verified technical context, package-specific pin functions, real-world use cases, and validated alternative options for design continuity and sourcing resilience.
Technical Context
The LMV824DR integrates four independent high-speed op-amps in a single SOIC-14 package, each featuring rail-to-rail output swing and input common-mode range extending to ground. Its architecture eliminates crossover distortion and supports stable operation with capacitive loads up to 22 pF when driving 600 Ω.
It operates across –40°C to +85°C, achieves 70 dB minimum CMRR and PSRR, and maintains >90 dB large-signal voltage amplification into 2 kΩ loads - making it suitable for precision DC-coupled amplification and active filtering where low quiescent current and wide supply flexibility are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - enables direct interface with Li-ion, 3.3 V, and 5 V logic rails without level-shifting. |
| Gain Bandwidth Product | 5.5 MHz typ at 5 V - supports stable closed-loop gain ≥10 at 500 kHz for anti-aliasing or reconstruction filters. |
| Slew Rate | 1.9 V/μs typ at 5 V - ensures <1% THD for 100 kHz, 2 VPP sine waves into 10 kΩ. |
| Input Offset Voltage | 4 mV max over –40°C to +85°C - reduces DC error in 12-bit ADC front-ends without trimming. |
| Output Swing | Within 170 mV of rails at 5 V, 600 Ω load - delivers full dynamic range in single-supply 10-bit DAC buffers. |
| Quiescent Current | 1.3 mA max (all four amps) at 5 V - allows continuous operation in always-on sensor nodes with <10 μA standby budget. |
| Common-Mode Input Range | –0.3 V to 4.3 V at 5 V supply - accepts signals referenced to ground or biased near VCC/2 in mixed-signal circuits. |
Pinout & Package
LMV824DR is housed in a 14-pin SOIC (D) package with standard 1.27 mm pitch and 8.65 mm × 3.91 mm footprint. Pin numbering follows JEDEC MS-012, with pin 1 marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Drives external load; rail-to-rail swing supports full-scale analog output. |
| 2 | Channel 1 Inverting Input | Accepts feedback or differential signal; high impedance (>100 GΩ) minimizes loading. |
| 3 | Channel 1 Non-Inverting Input | Reference or signal input; common-mode range includes ground for single-supply sensors. |
| 4 | Ground / Negative Supply | Return path for all channels; must be low-impedance to avoid crosstalk between amplifiers. |
| 5 | Channel 2 Non-Inverting Input | Independent input for second channel; electrically isolated from other inputs per datasheet isolation spec (135 dB). |
| 6 | Channel 2 Inverting Input | Feedback node for channel 2; matched bias current (<30 nA) enables precision integrators. |
| 7 | Channel 2 Output | Second independent output; same drive strength (20 mA sink/source) as channel 1. |
| 8 | Positive Supply | Single 2.5–5.5 V rail powers all four amplifiers; decoupling required within 1 cm. |
| 9 | Channel 3 Non-Inverting Input | Third channel input; identical specs to pins 3 and 5 - supports multi-channel signal conditioning. |
| 10 | Channel 3 Inverting Input | Third channel feedback node; no internal connection to other channels. |
| 11 | Channel 3 Output | Third independent output; rail-to-rail swing matches channels 1 and 2. |
| 12 | Channel 4 Inverting Input | Fourth channel feedback node; fully isolated per amplifier-to-amplifier isolation test (135 dB). |
| 13 | Channel 4 Non-Inverting Input | Fourth channel signal input; supports ground-referenced sources without level shift. |
| 14 | Channel 4 Output | Fourth rail-to-rail output; enables compact 4-channel instrumentation or multi-stage filtering. |
Key Features
| Feature | Design Value |
|---|---|
| No Crossover Distortion | Eliminates 2nd-harmonic artifacts in audio and sensor signal paths, preserving waveform fidelity below 100 kHz. |
| Rail-to-Rail Output Swing | Delivers >95% of full supply range at 600 Ω load, maximizing ADC utilization in 3.3 V systems. |
| Low 1 mA Supply Current (Quad) | Enables four simultaneous amplifiers in battery-powered devices with <100-hour runtime on 100 mAh cells. |
| 5.5 MHz Gain Bandwidth | Supports closed-loop gains of 100 at 50 kHz - sufficient for anti-aliasing before 100 kSPS SAR ADCs. |
| Amplifier-to-Amplifier Isolation | 135 dB min at 1 kHz prevents crosstalk in multi-channel data loggers or medical front-ends. |

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 |
|---|---|---|---|
| LMV824IDR | Same electrical specs but rated for –40°C to +125°C operating range; higher max input offset voltage (5.5 mV). | Required for automotive under-hood or industrial motor control environments exceeding 85°C ambient. | Select LMV824IDR only if extended temperature qualification is mandatory; otherwise LMV824DR offers identical performance at lower cost. |
| TLV2464CDR | Higher 6.4 MHz GBW and 1.6 V/μs slew rate; 1.2 mA supply current; wider input common-mode range (to VCC–0.2 V). | Better suited for higher-frequency active filters or faster-settling sample-and-hold circuits. | Choose TLV2464CDR when >5.5 MHz bandwidth or tighter input range is needed; LMV824DR remains optimal for cost-sensitive 5 MHz-class designs. |
Compared with LMV824IDR, LMV824DR trades extended temperature rating for lower cost and identical room-temperature performance; compared with TLV2464CDR, it offers lower power and proven stability with 22 pF capacitive loads - making LMV824DR the preferred choice for robust, low-cost, single-supply sensor interfaces.

FAQ
What is the maximum supply voltage for LMV824DR?
The absolute maximum supply voltage for LMV824DR is 5.5 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. The recommended operating range is 2.5 V to 5 V, where all electrical characteristics - including rail-to-rail output swing and 5.5 MHz gain bandwidth - are guaranteed across –40°C to +85°C.
Does LMV824DR support true rail-to-rail input?
No, LMV824DR does not support rail-to-rail input. Its input common-mode voltage range extends to ground (VCC–) but only up to 4.3 V at 5 V supply - i.e., within 0.7 V of VCC+. This allows ground-referenced signals but excludes full rail-to-rail input capability. For true rail-to-rail input, consider TI's TLV2464 or OPA333 families.
Can LMV824DR drive a 600 Ω load while maintaining rail-to-rail output swing?
Yes, LMV824DR delivers rail-to-rail output swing into 600 Ω loads at 5 V supply: high-level output reaches 4.7 V (within 300 mV of VCC) and low-level output sinks to 0.17 V (within 170 mV of ground). This is explicitly characterized in the 5-V Electrical Characteristics table and confirmed in Figure 5 (Sourcing Current vs Output Voltage) of the datasheet.
Is LMV824DR pin-compatible with other quad op-amps like LM324?
No, LMV824DR is not pin-compatible with LM324. LMV824DR uses a 14-pin SOIC package with dedicated pins for all four non-inverting inputs (pins 3, 5, 9, 13), whereas LM324 uses an 8-pin SOIC with shared power/ground and different pin mapping. Direct replacement requires PCB redesign. Use LMV824DR only in new layouts designed for its pinout.
What is the thermal resistance (θJA) of the LMV824DR SOIC package?
The junction-to-ambient thermal resistance (θJA) for the LMV824DR in the SOIC-14 (D) package is 97°C/W, as documented in the Absolute Maximum Ratings table. This value assumes standard JEDEC 2-layer board conditions (1-inch² copper pad). For sustained 1.3 mA operation at 5 V, junction temperature rise remains below 10°C - well within safe limits for –40°C to +85°C operation.
