Product details
Overview
LMV324AQPWRQ1 from Texas Instruments is a quad-channel, AEC-Q100 Grade 1 qualified automotive operational amplifier with rail-to-rail output, ±1 mV input offset voltage, 1 MHz unity-gain bandwidth, and 70 µA per channel quiescent current. It operates from 2.5 V to 5.5 V and delivers 20 mV rail-to-rail output swing into 10 kΩ at 5.5 V - enabling precision low-side current sensing in HEV/EV motor control and ADAS sensor interfaces.
For engineers reviewing the LMV324AQPWRQ1 datasheet, LMV324AQPWRQ1 pinout, LMV324AQPWRQ1 application, or LMV324AQPWRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to +125°C), resistive open-loop output impedance for stable capacitive-load drive up to 500 pF, integrated RFI/EMI filtering, and no-phase-reversal behavior under overdrive - all critical for safety-critical automotive signal conditioning.
Technical Context
The LMV324AQPWRQ1 implements a P-channel/N-channel parallel input stage to extend common-mode range to within 100 mV of V– and avoid phase reversal, while its class-AB output stage enables rail-to-rail swing with 1200 Ω open-loop output impedance at 1 MHz. This resistive impedance simplifies stability with high capacitive loads - unlike conventional op amps requiring external compensation.
It is unity-gain stable, features internal EMI/RFI filtering, and maintains 86 dB CMRR and 78 dB PSRR across –40°C to +125°C. Its 30 nV/√Hz input voltage noise density and 10 pA input bias current support high-impedance sensor interfacing in infotainment and body electronics without signal degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 5.5 V - supports single-supply operation in 3.3 V and 5 V automotive domains without level-shifting. |
| Input Offset Voltage | ±1 mV (typ) - enables accurate DC-coupled amplification in current-sense and battery-monitoring circuits. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for closed-loop response in motor control feedback and ADAS analog front-ends. |
| Quiescent Current | 70 µA per channel - allows four independent channels in always-on systems like door modules without excessive power draw. |
| Rail-to-Rail Output Swing | Within 20 mV of rails into 10 kΩ - maximizes dynamic range for ADC driving in 12-bit+ automotive data acquisition. |
| Capacitive Load Drive | Stable with ≥500 pF - eliminates need for isolation resistors when driving long traces or ESD-protected inputs in lighting control. |
| ESD Rating | HBM Level 2 (±2 kV), CDM Level C6 (±1 kV) - meets automotive board-level robustness requirements per AEC-Q100. |
Pinout & Package
TSSOP-14 (PW) package: 4.40 mm × 5.00 mm body, 0.65 mm pitch, surface-mount, moisture-sensitive level 1 - compatible with standard reflow profiles and space-constrained automotive ECUs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Connects to main 3.3 V or 5 V domain; decoupling capacitor required within 1 cm for EMI suppression. |
| V− | Negative supply or ground | Single-supply reference point; must be low-impedance return path shared with signal ground for rail-to-rail input operation. |
| OUT A–D | Amplifier outputs | Each drives independent load; rail-to-rail swing allows direct interface to SAR ADC references or comparator thresholds. |
| +IN A–D / −IN A–D | Differential input pairs | Accept common-mode voltages from V− − 0.1 V to V+ − 1 V; P/N parallel input prevents phase reversal during overdrive. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from –40°C to +125°C ambient, meeting thermal stress requirements of powertrain and ADAS modules. |
| Resistive open-loop output impedance | 1200 Ω at 1 MHz - enables stable operation with >500 pF capacitive loads without external series resistance or compensation networks. |
| No-phase-reversal input stage | Parallel P/N differential pair ensures monotonic output behavior even when inputs exceed V+ − 1 V, eliminating latch-up risk in fault conditions. |
| Integrated RFI/EMI filter | Rejects >60 dB of RF interference above 10 MHz - critical for reliable operation near switching regulators and wireless transceivers in vehicle cabins. |
| Low input bias current | 10 pA (typ) - minimizes voltage error across high-value gain-setting resistors (e.g., 1 MΩ) used in precision sensor signal chains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324AQDRQ1 | SOIC-14 package (8.65 mm × 3.91 mm); higher RθJA (115.1°C/W vs 135.3°C/W for TSSOP) | Better suited for through-hole prototyping or legacy PCBs with SOIC footprints; lower thermal performance in dense layouts. | Select when mechanical compatibility with existing SOIC-14 land patterns is required and airflow is adequate. |
| TSV914IQDT | Higher GBW (8 MHz), lower VOS (±0.3 mV), but not AEC-Q100 qualified; 150 µA/ch quiescent current. | Applicable only in non-safety-critical infotainment sub-systems where qualification is waived. | Choose only for cost-sensitive consumer-grade derivatives; not acceptable for ASIL-B or higher systems. |
Compared with LMV324AQPWRQ1, LMV324AQDRQ1 offers identical electrical specs in a larger, thermally less efficient SOIC package, while TSV914IQDT trades automotive qualification and ultra-low power for higher speed and precision - making LMV324AQPWRQ1 the sole choice for AEC-Q100-compliant, low-power quad-amplifier functions in production vehicles.

FAQ
What is the maximum capacitive load the LMV324AQPWRQ1 can drive stably?
The LMV324AQPWRQ1 is characterized for stable operation with ≥500 pF capacitive load due to its resistive open-loop output impedance. This eliminates the need for external isolation resistors in applications such as driving long PCB traces or ESD-protected inputs in automotive lighting control modules. Stability is verified per Figure 6-19 and 6-21 in the official datasheet SLOSE67D.
Does the LMV324AQPWRQ1 support true rail-to-rail input operation?
The LMV324AQPWRQ1 supports rail-to-rail *output* swing but has an input common-mode range extending from V− − 0.1 V to V+ − 1 V. While it accepts signals down to the negative rail, inputs must remain at least 1 V below V+ to maintain specified performance - a limitation addressed by its parallel P/N input stage to prevent phase reversal during overdrive.
What is the overload recovery time of the LMV324AQPWRQ1?
The LMV324AQPWRQ1 exhibits an overload recovery time of approximately 850 ns, defined as the time required for the output to transition from saturation back to linear operation after overdrive. This fast recovery enables accurate pulse-width measurement and transient detection in motor control feedback loops and battery protection circuits using the LMV324AQPWRQ1.
Is the LMV324AQPWRQ1 pin-compatible with the standard LMV324 family?
No - the LMV324AQPWRQ1 is not pin-compatible with non-Q1 versions. It shares the same TSSOP-14 footprint and pinout as other LMV324A-Q1 variants (e.g., LMV324AQDRQ1), but differs electrically and qualitatively from commercial-grade LMV324 devices, which lack AEC-Q100 qualification, extended temperature validation, and automotive-specific ESD/EMI hardening.
How does the LMV324AQPWRQ1 achieve EMI immunity?
The LMV324AQPWRQ1 integrates an on-chip RFI and EMI rejection filter, delivering >60 dB attenuation above 10 MHz (per Figure 6-30). This internal filtering suppresses noise from switching power supplies, CAN transceivers, and wireless modules - enabling reliable operation in electric vehicle cabins without additional external RC filters or ferrite beads.
