Product details
Overview
LMV324Q1MTX/NOPB from Texas Instruments is a quad-channel, rail-to-rail output operational amplifier designed for low-voltage (2.7 V to 5.5 V), single-supply operation in automotive and industrial systems. It delivers 1 MHz gain-bandwidth product, 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 ADAS sensors and engine control modules.
For engineers reviewing the LMV324Q1MTX/NOPB datasheet, LMV324Q1MTX/NOPB pinout, LMV324Q1MTX/NOPB application, or LMV324Q1MTX/NOPB equivalent, this AEC-Q100 Grade 1 qualified device supports design-in for automotive infotainment audio preamps, body control unit voltage monitoring, low-power sensor interfaces, and industrial PLC analog input stages where rail-to-rail output swing and ground-sensing capability are critical.
Technical Context
The LMV324Q1MTX/NOPB implements a bipolar input stage with BiCMOS process technology, delivering improved noise performance and higher output current drive versus CMOS-only op-amps. Its architecture eliminates crossover distortion and supports stable unity-gain operation with up to 200 pF capacitive load without external compensation.
It operates across −40°C to +125°C with guaranteed 2.7-V and 5-V performance, featuring input bias current of 15 nA (typ), input offset voltage of 1.7 mV (max), and CMRR of 50 dB (min) over full common-mode range - making it suitable for high-accuracy, low-drift single-supply transducer amplification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-voltage rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324DTBRG4 | Same silicon, SOIC-14 package, non-automotive grade (commercial temp −40°C to +125°C, no AEC-Q100 certification) | Lacks automotive qualification - unsuitable for safety-critical vehicle systems but lower cost for industrial prototypes | Select when AEC-Q100 is not required and cost sensitivity outweighs qualification needs |
| MCP6004-E/SL | CMOS input (0.1 pA bias current), lower supply current (100 µA/amp), but only 1 MHz GBW and no AEC-Q100 rating | Better for ultra-low-power battery devices; inferior drive strength and no automotive validation | Prefer for portable medical or IoT sensors where input bias current dominates error budget |
Compared with LMV324Q1MTX/NOPB, LMV324DTBRG4 offers identical electrical performance without automotive qualification, while MCP6004-E/SL trades bipolar output drive and AEC-Q100 compliance for ultra-low bias current and power - making LMV324Q1MTX/NOPB the only option meeting both automotive reliability and robust rail-to-rail output requirements.

FAQ
What is the maximum capacitive load LMV324Q1MTX/NOPB can drive without oscillation?
The LMV324Q1MTX/NOPB is characterized to drive up to 200 pF in unity-gain configuration without external compensation. This is validated per TI's datasheet Figure 7-23 (Gain and Phase vs Capacitive Load) and confirmed in Section 8.3.1. Exceeding this requires isolation resistors or feedback network adjustments - the LMV324Q1MTX/NOPB itself does not include internal compensation for heavier loads.
Does LMV324Q1MTX/NOPB support true single-supply operation with input signals at ground potential?
Yes. The LMV324Q1MTX/NOPB features an input common-mode voltage range extending to −0.2 V (with respect to V−), which includes ground in single-supply configurations where V− = 0 V. This allows direct interfacing with grounded sensors like thermistors or current shunts - explicitly confirmed in Section 7.4 and 7.7 of the datasheet.
What is the guaranteed input offset voltage specification for LMV324Q1MTX/NOPB over temperature?
The LMV324Q1MTX/NOPB has a maximum input offset voltage of 7 mV at TJ = 25°C and 9 mV over the full −40°C to +125°C operating range (Section 7.9). This is ensured by production testing - not a typical value - and applies to all four amplifiers within the same package.
Is LMV324Q1MTX/NOPB pin-compatible with standard LM324 or LMV324-N variants?
Yes. LMV324Q1MTX/NOPB uses the industry-standard 14-pin SOIC (D package) footprint and identical pinout to LM324, LMV324-N, and LMV324-N-Q1. Pin assignments match TI's documented D-package configuration (Figure 6-3), enabling drop-in replacement in existing designs - provided AEC-Q100 qualification and automotive temperature range are required.
What packaging and marking information is associated with LMV324Q1MTX/NOPB?
LMV324Q1MTX/NOPB is supplied in tape-and-reel format (2500 units per reel) in a 14-pin SOIC package (body size 8.65 mm × 3.91 mm). The 'NOPB' suffix indicates lead-free (Pb-free) and RoHS-compliant finish; 'Q1' denotes AEC-Q100 Grade 1 qualification; 'MTX' is TI's orderable part number variant for this specific packaging and screening level.
