Product details
Overview
LMV324Q1MAX/NOPB from Texas Instruments is a quad, rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 5.5 V), single-supply operation in automotive and industrial systems. It delivers 1 MHz gain-bandwidth, 1 V/µs slew rate, 410 µA typical supply current per amplifier, −0.2 V to 4.0 V input common-mode range (including ground), and rail-to-rail output swing (V+ −10 mV / V− +65 mV at 10 kΩ) - enabling precision signal conditioning in battery-powered sensor interfaces and analog front-ends.
For engineers reviewing the LMV324Q1MAX/NOPB datasheet, LMV324Q1MAX/NOPB pinout, LMV324Q1MAX/NOPB application, or LMV324Q1MAX/NOPB equivalent, this page provides verified technical context, exact SOIC-14 pin mapping, automotive-grade AEC-Q100 Grade 1 qualification, real-world application cards, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The LMV324Q1MAX/NOPB implements a bipolar-input, rail-to-rail output architecture with no crossover distortion, ensuring clean zero-crossing behavior in unity-gain buffers and active filters. Its input stage supports common-mode voltage down to −0.2 V (below ground) and up to V+ − 0.8 V, while the output drives within 10 mV of V+ and 65 mV of V− under 10-kΩ load.
It operates across −40°C to +125°C with guaranteed 2.7-V and 5-V performance, delivering 1 MHz GBWP and 1 V/µs slew rate while consuming only 410 µA per amplifier at 5 V - achieving high speed-to-power efficiency without external compensation for capacitive loads ≤200 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports full operation across Li-ion battery discharge curve (3.0 V–4.2 V) and 3.3-V/5-V rails. |
| Gain-Bandwidth Product | 1 MHz - enables stable unity-gain buffer and 2nd-order active filter designs up to ~100 kHz. |
| Slew Rate | 1 V/µs - sufficient for 100-kHz sine wave output at 1-V amplitude without distortion. |
| Input Offset Voltage | 1.7 mV (max) - limits DC error in precision gain stages; drift <5 µV/°C ensures stability over temperature. |
| Rail-to-Rail Output Swing | V+ −10 mV / V− +65 mV @ 10 kΩ - maximizes dynamic range in low-voltage ADC driver applications. |
| Input Common-Mode Range | −0.2 V to V+ − 0.8 V - allows direct sensing of signals referenced to ground in single-supply systems. |
| Quiescent Current (per amp) | 410 µA (typ) at 5 V - enables four-channel amplification with <1.7 mA total supply current. |
Pinout & Package
LMV324Q1MAX/NOPB is housed in a 14-pin SOIC package (8.65 mm × 3.91 mm body size), qualified for surface-mount reflow and compatible with standard PCB assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN A− | Inverting input of amplifier A - connects to feedback network in inverting configurations. |
| 2 | IN A+ | Noninverting input of amplifier A - accepts sensor or reference signal in noninverting gain stages. |
| 3 | OUT A | Output of amplifier A - drives downstream circuitry; rail-to-rail swing enables full utilization of ADC input range. |
| 4 | V− | Negative supply terminal - tied to GND in single-supply operation; must be decoupled with 0.1-µF ceramic capacitor. |
| 5 | IN B+ | Noninverting input of amplifier B - used for independent channel processing (e.g., dual-sensor conditioning). |
| 6 | IN B− | Inverting input of amplifier B - forms differential pair with IN B+ for noise-rejecting instrumentation topologies. |
| 7 | OUT B | Output of amplifier B - isolated from OUT A; supports multi-channel signal routing without crosstalk. |
| 8 | V+ | Positive supply terminal - accepts 2.7–5.5 V; requires local 0.1-µF bypass capacitor near pin. |
| 9 | IN C− | Inverting input of amplifier C - enables third independent gain stage (e.g., reference buffer + signal path). |
| 10 | IN C+ | Noninverting input of amplifier C - accepts bias or calibration signal in multi-stage analog chains. |
| 11 | OUT C | Output of amplifier C - maintains channel separation; usable for driving LED bias or DAC output buffers. |
| 12 | IN D+ | Noninverting input of amplifier D - supports fourth analog function (e.g., fault detection comparator input). |
| 13 | IN D− | Inverting input of amplifier D - configurable as comparator input or feedback node in programmable gain stages. |
| 14 | OUT D | Output of amplifier D - fully independent; suitable for redundant monitoring or auxiliary signal generation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324DR | Commercial-grade (non-automotive); same SOIC-14 package, identical electrical specs except AEC-Q100 not certified. | Lacks automotive qualification - unsuitable for safety-critical vehicle subsystems but acceptable for industrial controls. | Select LMV324DR for cost-sensitive non-automotive designs where AEC-Q100 is not mandated. |
| TSV914IQDT | Higher GBWP (8 MHz), lower VOS (1.5 mV max), but higher IQ (820 µA per amp); TSSOP-14 package (5.0 mm × 4.4 mm). | Better AC performance for wideband filtering, but increased power draw limits battery lifetime in portable devices. | Choose TSV914IQDT when bandwidth >1 MHz or offset <1.7 mV is required, accepting higher supply current and different footprint. |
Compared with LMV324Q1MAX/NOPB, LMV324DR offers identical analog performance at lower cost but no automotive qualification, while TSV914IQDT trades higher power for 8× bandwidth and tighter offset - making LMV324Q1MAX/NOPB optimal for AEC-Q100-compliant, low-power, cost-driven quad-op-amp applications.

FAQ
What is the operating temperature range for LMV324Q1MAX/NOPB?
The LMV324Q1MAX/NOPB is qualified for continuous operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This range is validated across all electrical parameters including input offset voltage, gain-bandwidth, and output swing - ensuring reliable performance in under-hood automotive environments and industrial enclosures without derating.
Does LMV324Q1MAX/NOPB support true single-supply operation?
Yes, LMV324Q1MAX/NOPB supports true single-supply operation from 2.7 V to 5.5 V. Its input common-mode range extends to −0.2 V (below ground) and its rail-to-rail output swings within 10 mV of V+ and 65 mV of V−, enabling direct interfacing with ground-referenced sensors and 3.3-V ADCs without level-shifting circuitry.
Is LMV324Q1MAX/NOPB pin-compatible with standard LM324 variants?
No, LMV324Q1MAX/NOPB is not pin-compatible with legacy LM324 variants. While both use SOIC-14 packages, the LMV324Q1MAX/NOPB pinout follows the modern TI LMV324 layout (e.g., V− on pin 4, V+ on pin 8), whereas LM324 places V− on pin 4 and V+ on pin 11. Direct substitution requires PCB redesign.
What is the maximum capacitive load LMV324Q1MAX/NOPB can drive without instability?
LMV324Q1MAX/NOPB can directly drive up to 200 pF in unity-gain configuration without oscillation or excessive ringing, as confirmed by phase margin measurements ≥60°. For loads exceeding 200 pF (e.g., long PCB traces or ADC inputs), a series isolation resistor (e.g., 620 Ω) between output and load restores stability while preserving DC accuracy.
How does the input bias current of LMV324Q1MAX/NOPB affect precision designs?
LMV324Q1MAX/NOPB exhibits typical input bias current of 15 nA at 5 V, with max 250 nA over temperature. In high-impedance sensor interfaces (e.g., >100 kΩ source), this causes offset errors up to 25 µV/kΩ. Designers mitigate this by matching source impedances at both inputs or using low-value feedback networks to minimize voltage drop.
