Product details
Overview
LMV324LIDT from STMicroelectronics is a quad rail-to-rail output operational amplifier optimized for low-voltage, low-power applications. It delivers 1.3 MHz gain bandwidth, 250 µA max supply current per channel at 5 V, 7 mV max input offset voltage at 25 °C, and operates across -40 °C to +125 °C. It is used in battery-powered signal conditioning circuits where rail-to-rail swing and industrial temperature stability are critical.
For engineers reviewing the LMV324LIDT datasheet, LMV324LIDT pinout, LMV324LIDT application, or LMV324LIDT equivalent, this page provides verified technical context, SO14 package mapping, real-world use scenarios, and validated alternative options - all grounded in ST's production-grade documentation (DocID023066 Rev 3).
Technical Context
The LMV324LIDT integrates four independent op-amps in a single SO14 package, each featuring rail-to-rail output swing (within 180 mV of rails at 10 kΩ load) and an input common-mode range extending from (VCC–) – 0.2 V to (VCC+) – 1 V - enabling ground-sensing capability without phase reversal. Its 1.3 MHz GBP and 0.7 V/µs slew rate support stable unity-gain buffer and active filter configurations at low supply voltages (2.7–5.5 V).
Designed for cost-sensitive, space-constrained systems, it replaces legacy LM324 variants with enhanced DC precision (7 mV VIO max), lower quiescent current (250 µA/channel), and extended temperature operation up to +125 °C - making it suitable for automotive body electronics and industrial sensor front-ends where thermal robustness and supply flexibility are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion and dual-cell alkaline battery systems without regulation. |
| Gain Bandwidth Product | 1.3 MHz - enables stable closed-loop operation up to ~100 kHz in unity-gain buffer or 2nd-order active filters. |
| Input Offset Voltage | 7 mV max at 25 °C - ensures ≤0.7% error in 1 V full-scale DC-coupled sensor amplification. |
| Supply Current per Channel | 250 µA max at 5 V - allows four-channel operation under 1 mA total, critical for multi-sensor IoT nodes. |
| Rail-to-Rail Output Swing | Within 180 mV of VCC+ and VCC– at 10 kΩ load - maximizes dynamic range in 3.3 V or 5 V ADC interfacing. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive and industrial control environments. |
| Input Common-Mode Range | (VCC–) – 0.2 V to (VCC+) – 1 V - permits direct sensing of signals referenced to ground in single-supply systems. |
Pinout & Package
LMV324LIDT is supplied in a 14-pin SOIC (SO14) package with standard 1.27 mm pitch, 8.55–8.75 mm body length, and 3.80–4.00 mm width - compatible with automated SMT assembly and legacy SOIC footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 10, 13 | Output (OUT1–OUT4) | Rail-to-rail buffered output per amplifier; drives 10 kΩ loads to within 180 mV of supply rails. |
| 2, 5, 8, 11 | Inverting Input (IN1– – IN4–) | Differential input node; accepts signals within (VCC–) – 0.2 V to (VCC+) – 1 V common-mode range. |
| 3, 6, 9, 12 | Non-inverting Input (IN1+ – IN4+) | Differential input node; same common-mode range as inverting inputs; no phase reversal observed. |
| 4 | VCC– (Ground) | Reference terminal for single-supply operation; must be decoupled with 10 nF capacitor near pin. |
| 14 | VCC+ (Supply) | Positive supply rail (2.7–5.5 V); requires local 10 nF decoupling to maintain AC stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power consumption | 250 µA max per channel at 5 V - enables always-on sensor signal conditioning in energy-harvested systems. |
| Rail-to-rail output stage | Swings to within 180 mV of both supply rails at 10 kΩ - preserves >94% of full-scale ADC range in 3.3 V systems. |
| Industrial temperature grade | Specified from -40 °C to +125 °C - eliminates derating concerns in engine control modules and motor drives. |
| Low input offset voltage | 7 mV max at 25 °C - reduces zero-error drift in precision transducer amplifiers without external trimming. |
| Small-footprint SO14 package | Standard 14-pin SOIC footprint - enables drop-in replacement of legacy quad op-amps without PCB redesign. |

IC Role / Device Role / Timing Role: Dual op-amps for I/V conversion and gain staging; third for excitation buffer; fourth for diagnostic comparator reference. Use Value: -40 °C to +125 °C operation ensures calibration stability across ambient extremes; 7 mV VIO max limits span error to <0.1% FS in 100 mV bridge outputs. |

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 |
|---|---|---|---|
| LM324DT | Higher 1.2 mA/channel supply current; 3 mV typical (7 mV max) VIO; no rail-to-rail output (swing limited to ~1.5 V from rails at 5 V). | Acceptable only in non-battery applications with ample headroom; unsuitable for 3.3 V ADC interfacing or low-power sleep modes. | Select when cost is paramount and thermal/size constraints are relaxed; verify output swing margin against ADC input range. |
| TSV914IYDT | Lower 80 µA/channel supply current; 1.3 MHz GBP; rail-to-rail input/output; 1.1 mV max VIO at 25 °C. | Better precision and lower power, but rated only to +105 °C - not qualified for under-hood or high-temp industrial use. | Prefer for portable consumer devices needing tighter DC accuracy; avoid where ambient exceeds +105 °C or AEC-Q200 qualification is required. |
Compared with LM324DT, LMV324LIDT cuts quiescent power by 79% and adds rail-to-rail output - essential for modern low-voltage systems. Against TSV914IYDT, it trades 1.1 mV VIO for +125 °C operation and broader supply range, making it the sole choice for thermally demanding industrial deployments.

FAQ
Is LMV324LIDT pin-compatible with standard LM324 SO14 packages?
Yes - LMV324LIDT uses identical SO14 pinout and footprint as LM324DT, including matching VCC+ (pin 14), VCC– (pin 4), and channel I/O assignments. However, its rail-to-rail output and lower supply current require verification of load drive capability and decoupling in legacy designs.
What is the maximum capacitive load the LMV324LIDT can drive stably?
Per Figure 9 in the datasheet, phase margin remains ≥60° with up to 200 pF capacitive load at 5 V supply and 100 kΩ resistive load. For loads >200 pF, external series resistance (≥100 Ω) is recommended at the output to maintain stability in unity-gain configurations.
Does LMV324LIDT support true rail-to-rail input?
No - LMV324LIDT features rail-to-rail *output* only. Its input common-mode range extends from (VCC–) – 0.2 V to (VCC+) – 1 V, meaning it accepts ground-referenced signals but cannot handle inputs at the positive rail. True rail-to-rail input requires devices like TSV914.
Can LMV324LIDT operate from a 2.7 V single supply with full functionality?
Yes - all key specifications (GBP, VIO, output swing, supply current) are guaranteed at 2.7 V per Tables 3 and 4. Output swing degrades slightly (to ~2.6 V high / 180 mV low at 10 kΩ), but remains fully functional for 12-bit ADC interfacing in ultra-low-power systems.
