Product details

Overview

LMV324Q1MT/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 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 body control modules.

For engineers reviewing the LMV324Q1MT/NOPB datasheet, LMV324Q1MT/NOPB pinout, LMV324Q1MT/NOPB application, or LMV324Q1MT/NOPB equivalent, this AEC-Q100 Grade 1 qualified device supports design-in for automotive infotainment front-ends, HVAC sensor interfaces, LED driver feedback loops, and low-power industrial PLC analog I/O where rail-to-rail output, ground-sensing inputs, and guaranteed 125°C operation are required.

Technical Context

The LMV324Q1MT/NOPB implements a bipolar-input, rail-to-rail output stage on TI's submicron BiCMOS process, delivering low-noise performance (39 nV/√Hz at 1 kHz) and high output drive (±40 mA short-circuit current) without crossover distortion. Its input common-mode range extends to V₋ − 0.2 V, supporting true ground-referenced sensing in single-supply configurations.

It operates across 2.7 V–5.5 V with guaranteed DC/AC specifications at both 2.7 V and 5 V, including 7 mV max input offset voltage, 65 dB min CMRR (0 V ≤ V_CM ≤ 4 V), and 60 dB min PSRR - making it suitable for precision DC-coupled amplification and active filtering in harsh automotive environments.

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 nominal 5 V rails without brownout.
Gain-Bandwidth Product	1 MHz - enables stable unity-gain buffer and 2nd-order active filters up to ~100 kHz with adequate phase margin.
Slew Rate	1 V/µs - sufficient for 100 kHz sine wave output at 16 V_PP without distortion in closed-loop configurations.
Input Offset Voltage	7 mV max (25°C, 5 V) - limits DC error to <1% of full-scale in 1 V reference applications with 100× gain.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LMV324DTBRG4	Same electrical specs and SOIC-14 package, but commercial-grade (non-AEC-Q100) and rated only to 85°C.	Not qualified for automotive under-hood or safety-critical functions; limited to infotainment head units or non-safety cabin modules.	Select when cost is primary constraint and automotive qualification is unnecessary.
TSV914IQ4T	Higher 8 MHz GBW, lower 1.8 mV V_OS, but higher 820 µA supply current and only AEC-Q100 Grade 2 (−40°C to +105°C).	Better for high-speed sensor sampling or precision instrumentation, but insufficient for 125°C ECU applications.	Select when bandwidth >1 MHz or offset <2 mV is mandatory, and ambient temperature stays ≤105°C.

Compared with LMV324Q1MT/NOPB, LMV324DTBRG4 lacks automotive qualification and high-temp guarantee, while TSV914IQ4T trades off thermal robustness and quiescent current for higher speed and precision - making LMV324Q1MT/NOPB the optimal balance for cost-sensitive, thermally demanding automotive analog front-ends.

FAQ

What is the maximum operating temperature for LMV324Q1MT/NOPB?

LMV324Q1MT/NOPB is AEC-Q100 Grade 1 qualified and fully specified from −40°C to +125°C ambient temperature. All electrical parameters - including input offset voltage, CMRR, and output swing - are guaranteed across this full range, making it suitable for under-hood engine control units and transmission control modules where junction temperatures may exceed 125°C with proper thermal design.

Does LMV324Q1MT/NOPB support true single-supply operation with input signals at ground?

Yes. LMV324Q1MT/NOPB features an input common-mode voltage range extending to V₋ − 0.2 V (i.e., −0.2 V when V₋ = 0 V), enabling direct connection of ground-referenced sensors like thermistors, current shunts, or potentiometers without external level-shifting circuitry - a key advantage over legacy LM324 variants.

Can LMV324Q1MT/NOPB drive capacitive loads without oscillation?

LMV324Q1MT/NOPB is stable driving up to 200 pF in unity-gain configuration, as confirmed in the datasheet's "Gain and Phase vs Capacitive Load" plots. For heavier loads (e.g., LCD bias lines or long cables), external isolation resistors (e.g., 620 Ω in series with output) restore phase margin without degrading DC accuracy when combined with feed-forward compensation.

What is the typical supply current for LMV324Q1MT/NOPB at 5 V?

At V₊ = 5 V and T_A = 25°C, LMV324Q1MT/NOPB draws 410 µA per amplifier (1.64 mA total for all four channels), with a maximum of 830 µA per amplifier over temperature. This ultra-low quiescent current enables use in always-on automotive subsystems such as door module wake-up logic or battery monitoring circuits.

Is LMV324Q1MT/NOPB pin-compatible with standard LM324 packages?

LMV324Q1MT/NOPB uses the same 14-pin SOIC (D package) footprint as LM324, LM324N, and LMV324-N, with identical pin assignments for all four amplifier channels, power, and ground terminals. However, due to its rail-to-rail output architecture and wider input common-mode range, it is not a drop-in replacement in designs relying on LM324's limited output swing or input range - circuit validation is required.
