Product details
Overview
LMV324Q1MA/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 industrial and automotive applications. It delivers 1 MHz gain-bandwidth product, 1 V/µs slew rate, 410 µA typical supply current per amplifier, −0.2 V to 4.0 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 automotive body control modules.
For engineers reviewing the LMV324Q1MA/NOPB datasheet, LMV324Q1MA/NOPB pinout, LMV324Q1MA/NOPB application, or LMV324Q1MA/NOPB equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, guaranteed 2.7-V operation, absence of crossover distortion, thermal performance in SOIC-14 (RθJA = 145 °C/W), and compatibility with space-constrained, low-noise analog front-ends requiring ground-sensing capability.
Technical Context
The LMV324Q1MA/NOPB implements a bipolar-input, rail-to-rail output architecture optimized for low-voltage stability and noise performance. Its input stage supports common-mode voltage down to −0.2 V (enabling true ground-referenced sensing), while the output stage achieves V+ − 10 mV high-side and V− + 65 mV low-side swing into 10 kΩ loads - critical for maximizing dynamic range in 3.3-V and 5-V systems.
It features inherent capacitive load tolerance up to 200 pF in unity-gain configuration without oscillation, enabled by internal compensation and low output impedance. The device operates across −40°C to +125°C with guaranteed DC/AC specs at both 2.7 V and 5 V, and exhibits 5 µV/°C input offset drift and 65 dB CMRR over its full common-mode range.

Its thermal design supports continuous operation at +125°C with appropriate PCB copper pour and airflow, and it maintains guaranteed DC/AC performance across this full range - essential for engine control, transmission, and ADAS applications.
Does LMV324Q1MA/NOPB support true single-supply operation with ground-referenced inputs?
Yes. The LMV324Q1MA/NOPB features an input common-mode voltage range extending to −0.2 V (below ground) and up to V+ − 0.8 V, enabling direct connection of ground-referenced sensors like thermistors, RTDs, and bridge transducers without external level-shifting circuitry - a key advantage over legacy op-amps requiring dual supplies.
What is the output drive capability of LMV324Q1MA/NOPB into capacitive loads?
The LMV324Q1MA/NOPB is stable driving up to 200 pF in unity-gain configuration without external compensation. This allows direct interfacing to ADC input capacitors, LCD column lines, or long PCB traces. For heavier loads (>200 pF), TI recommends adding a series isolation resistor (e.g., 620 Ω) between output and load to preserve phase margin and prevent oscillation.
How does the rail-to-rail output of LMV324Q1MA/NOPB improve system performance?
The LMV324Q1MA/NOPB delivers output swing to within 10 mV of V+ and 65 mV of V− at 10 kΩ load - achieving >99% of full-scale range at 3.3 V. This maximizes effective ADC resolution, improves signal-to-noise ratio in data acquisition, and eliminates clipping in precision analog signal chains operating from low-voltage rails.
Is LMV324Q1MA/NOPB pin-compatible with legacy LM324 variants?
No. While functionally similar to the LM324 family, the LMV324Q1MA/NOPB uses a different internal architecture optimized for low-voltage operation and has distinct electrical characteristics (e.g., rail-to-rail output, ground-sensing input, lower supply current). It shares the SOIC-14 package footprint with LM324 but is not a drop-in replacement due to differences in input/output voltage ranges and biasing requirements.
