Product details
Overview
LMV324Q3MT/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-grade applications. It delivers 1 MHz gain-bandwidth product, 1 V/µs slew rate, 410 µA typical supply current per amplifier, −0.2 V to 4 V input common-mode range (including ground), and rail-to-rail output swing (V+ −10 mV / V− +65 mV at 10 kΩ load). It is used in battery-powered sensor signal conditioning and automotive body control modules.
For engineers reviewing the LMV324Q3MT/NOPB datasheet, LMV324Q3MT/NOPB pinout, LMV324Q3MT/NOPB application, or LMV324Q3MT/NOPB equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options - all grounded in TI's official SNOS012K revision K datasheet and AEC-Q100 Grade 3 qualification documentation.
Technical Context
The LMV324Q3MT/NOPB implements a bipolar-input, rail-to-rail output architecture with no crossover distortion, enabling clean small-signal amplification near ground in single-supply configurations. Its input stage supports common-mode voltage down to −0.2 V, and its output drives within 10 mV of V+ and 65 mV of V− under 10 kΩ load.
It operates across −40°C to +85°C (Grade 3), meets AEC-Q100 stress test requirements, and is specified for stable unity-gain operation with up to 200 pF capacitive load. The device uses TI's submicron BiCMOS process to balance noise performance (39 nV/√Hz at 1 kHz), output drive capability (±40 mA short-circuit current), and ultra-low quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports full operation across depleted Li-ion (3.0 V) and regulated 3.3 V/5 V rails. |
| Gain-Bandwidth Product | 1 MHz - enables stable unity-gain buffer or gain-of-10 amplification up to 100 kHz. |
| Slew Rate | 1 V/µs - sufficient for 100 kHz sine wave output at 16 VPP without distortion. |

| 3 | OUT A | Output of amplifier channel A - drives downstream ADC input, filter stage, or actuator interface. |
| 4 | V− | Negative supply terminal - tied to system ground in single-supply operation; must be decoupled locally. |
| 5 | IN B− | Inverting input for amplifier channel B - isolated from channel A for dual-sensor signal paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad general-purpose op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324QDRQ1 | Same quad rail-to-rail output architecture, identical pinout, but AEC-Q100 Grade 1 (−40°C to +125°C) and SOIC-14 package (8.65 mm × 3.91 mm). | Preferred for under-hood applications requiring extended temperature range; larger SOIC footprint increases PCB area by 68%. | Select LMV324QDRQ1 when operating above 85°C or when legacy SOIC layout compatibility is required. |
| MCP6004-E/ST | Quad rail-to-rail input/output op-amp; wider supply range (1.8 V to 6.0 V); higher input bias current (1 pA typ vs 15 nA); 1 MHz GBWP same. | Better suited for ultra-low-power (<1 µA) or wide-VCC applications; lacks AEC-Q100 qualification and automotive temp range. | Choose MCP6004-E/ST only for non-automotive, low-voltage (<2.7 V) designs where input bias current sensitivity dominates. |
Compared with LMV324Q3MT/NOPB, LMV324QDRQ1 offers extended temperature capability in a larger SOIC package, while MCP6004-E/ST provides rail-to-rail input and lower minimum supply voltage but no automotive qualification - making LMV324Q3MT/NOPB the optimal balance of Grade 3 compliance, TSSOP space efficiency, and proven 2.7–5.5 V performance.

FAQ
What is the operating temperature range for LMV324Q3MT/NOPB?
The LMV324Q3MT/NOPB is qualified to AEC-Q100 Grade 3, supporting continuous operation from −40°C to +85°C. This range is validated per automotive stress test standards and covers cabin-mounted modules such as door controllers, seat position sensors, and HVAC interfaces. It does not support Grade 1 (−40°C to +125°C) under-hood applications - for those, LMV324QDRQ1 is the designated alternative.
Does LMV324Q3MT/NOPB support true rail-to-rail input?
No, LMV324Q3MT/NOPB features rail-to-rail *output* swing but not rail-to-rail input. Its input common-mode voltage range is specified from −0.2 V to V+ − 0.8 V, which includes ground but does not extend to the positive rail. For applications requiring input signals up to V+, consider alternatives like MCP6004-E/ST - though that part lacks AEC-Q100 qualification and automotive temperature range.
What is the maximum capacitive load LMV324Q3MT/NOPB can drive without compensation?
LMV324Q3MT/NOPB is stable driving up to 200 pF in unity-gain follower configuration, as confirmed in TI's SNOS012K datasheet Figure 7-23. This applies directly to sensor output buffering and ADC input driving where trace capacitance or input capacitance falls within this limit. For loads exceeding 200 pF, TI recommends adding a series isolation resistor (e.g., 620 Ω) between the op-amp output and the capacitive node to restore phase margin.
Is LMV324Q3MT/NOPB pin-compatible with standard LM324 variants?
No, LMV324Q3MT/NOPB is not pin-compatible with legacy LM324 variants. While both are quad op-amps in 14-pin packages, LM324 uses a different pinout (e.g., V+ on pin 4, V− on pin 11) versus LMV324Q3MT/NOPB (V− on pin 4, V+ on pin 11). Attempting drop-in replacement will cause power polarity reversal and immediate device failure. Board redesign is required for migration.
What packaging and marking details confirm authenticity of LMV324Q3MT/NOPB?
Authentic LMV324Q3MT/NOPB devices ship in TI-qualified TSSOP-14 tape-and-reel packaging with top-side marking "LMV324Q3M" followed by date code and factory logo. The "/NOPB" suffix denotes lead-free (Pb-free) finish per JEDEC J-STD-609. Counterfeit risk is mitigated through Aetrix Electronics' traceable sourcing from TI-authorized distributors - batch verification includes TI's proprietary laser-marked date codes and package mold compound identifiers.
