Product details
Overview
LMV824Q1MA/NOPB from Texas Instruments is a quad, rail-to-rail output (RRO), low-voltage (2.5 V to 5.5 V), low-power operational amplifier qualified for automotive applications per AEC-Q100 Grade 1 (−40°C to +125°C). It delivers 5 MHz gain-bandwidth product at 2.7 V, 1.4 V/µs slew rate, 3.5 mV max input offset voltage, and 220 µA per amplifier supply current - enabling precision signal conditioning in space-constrained automotive body electronics and infotainment interfaces.
For engineers reviewing the LMV824Q1MA/NOPB datasheet, LMV824Q1MA/NOPB pinout, LMV824Q1MA/NOPB application, or LMV824Q1MA/NOPB equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, rail-to-rail output swing into 600 Ω (160 mV from rail), −40°C to +125°C operating range, and TSSOP-14 package compatibility with automotive PCB layout standards.
Technical Context
The LMV824Q1MA/NOPB implements a CMOS input stage with rail-to-rail output architecture optimized for single-supply operation down to 2.5 V. Its internal design ensures stable performance with capacitive loads up to 100 pF and maintains ≥61° phase margin across 600 Ω to 10 kΩ loads at both 2.7 V and 5 V supplies.
It features matched amplifier channels with ≤50 nA input bias current, 90 dB minimum CMRR over 0 V to 4.3 V common-mode range, and 85 dB PSRR - supporting accurate DC-coupled sensing and low-noise amplification in automotive sensor front-ends and power management monitoring circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824IDR | Industrial-grade (−40°C to +85°C), same TSSOP-14 package and pinout, identical electrical specs except AEC-Q100 not certified | Not qualified for automotive safety-critical modules requiring AEC-Q100 documentation traceability | Select when cost sensitivity outweighs automotive qualification requirements and ambient temperature stays ≤85°C |
| MCP6004-E/ST | Microchip quad op-amp in TSSOP-14; 1 MHz GBW, 0.6 V/µs slew rate, 4.5 mV VOS max, 100 µA per amp | Limited bandwidth and slew rate restrict use to sub-100 kHz sensor buffering; lower power but reduced precision | Choose for ultra-low-power battery-backed modules where 5 MHz performance is unnecessary and 100 µA quiescent current is critical |
Compared with LMV824Q1MA/NOPB, LMV824IDR offers identical performance without automotive qualification, while MCP6004-E/ST trades bandwidth and precision for lower power - making LMV824Q1MA/NOPB optimal for AEC-Q100-compliant, wideband automotive signal conditioning.

FAQ
What automotive qualification level does LMV824Q1MA/NOPB meet?
The LMV824Q1MA/NOPB is AEC-Q100 qualified to Grade 1, meaning it is tested and certified for operation from −40°C to +125°C with full reliability validation including HTOL, temperature cycling, and ESD robustness. This makes LMV824Q1MA/NOPB suitable for engine bay, dashboard, and powertrain-adjacent applications where extended temperature performance is mandatory.
Does LMV824Q1MA/NOPB support true single-supply operation with input common-mode range extending to ground?
Yes, LMV824Q1MA/NOPB supports true single-supply operation with an input common-mode voltage range from −0.3 V to 4.3 V at 5 V supply - explicitly including ground (0 V). This allows direct interfacing with grounded sensors, resistive dividers, and other base-referenced sources without level-shifting circuitry, simplifying design in automotive sensor signal chains.
What is the maximum capacitive load LMV824Q1MA/NOPB can drive while maintaining stability?
LMV824Q1MA/NOPB is characterized for stable operation with capacitive loads up to 100 pF, as confirmed in the datasheet's Figure 22–25 (gain/phase margin vs. CL). For loads exceeding 100 pF, external series isolation resistance (e.g., 10–50 Ω) is recommended to preserve phase margin and prevent peaking or oscillation in high-impedance sensor or filter buffer configurations.
How does the rail-to-rail output performance of LMV824Q1MA/NOPB compare at 2.7 V versus 5 V supply?
At 2.7 V supply, LMV824Q1MA/NOPB delivers 2.50 V high-side and 0.13 V low-side output into 600 Ω; at 5 V supply, it achieves 4.75 V high-side and 0.17 V low-side swing under the same load. The absolute voltage headroom from rails remains consistent (~160–200 mV), confirming robust RRO behavior across the full 2.5–5.5 V operating range - critical for consistent ADC interface performance.
Can LMV824Q1MA/NOPB be used in dual-supply configurations?
Yes, LMV824Q1MA/NOPB supports dual-supply operation with V+ and V− pins accepting symmetric or asymmetric rails, provided the total supply voltage remains within 2.5 V to 5.5 V and V− does not fall below −0.3 V. The input common-mode range and output swing scale accordingly - e.g., with ±2.5 V supplies, VCM extends from −2.8 V to +2.2 V, enabling bipolar signal processing in automotive test equipment interfaces.
