Product details
Overview
LMV324AQDYYRQ1 from Texas Instruments is a quad-channel, automotive-grade operational amplifier with rail-to-rail output, AEC-Q100 Grade 1 qualification (–40°C to +125°C), ±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 serves as a low-power signal conditioning amplifier in HEV/EV motor control current sensing and ADAS sensor front-ends.
For engineers reviewing the LMV324AQDYYRQ1 datasheet, LMV324AQDYYRQ1 pinout, LMV324AQDYYRQ1 application, or LMV324AQDYYRQ1 equivalent, key selection criteria include its resistive open-loop output impedance (1200 Ω at 1 MHz), 500 pF capacitive-load drive capability, integrated RFI/EMI filtering, and guaranteed no phase reversal under overdrive - all critical for robust single-supply automotive signal chains.
Technical Context
The LMV324AQDYYRQ1 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 (within 20 mV of rails at 10 kΩ load). Its unity-gain stability and 76° phase margin at G = 1 support direct use in gain-of-one configurations without external compensation.
Designed specifically for automotive low-voltage systems, it features internal ESD protection (HBM Level 2, CDM Level C6), operates down to 2.5 V, and maintains 86 dB CMRR and 78 dB PSRR across –40°C to 125°C - enabling reliable performance in infotainment power supplies and body electronics sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - supports simultaneous signal conditioning for four independent sensors or feedback loops in compact ECUs. |
| Supply Voltage | 2.5 V to 5.5 V - compatible with 3.3 V and 5 V automotive domains, including CAN/LIN interface power rails. |
| Input Offset Voltage | ±1 mV (typ) - enables accurate low-side current sensing with ≤0.1% gain error at 100 mV shunt voltage. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for closed-loop response in motor phase current monitoring up to ~100 kHz bandwidth. |
| Quiescent Current | 70 µA per channel - allows four amplifiers to consume <300 µA total, critical for always-on ADAS subsystems. |
| Output Swing | Within 20 mV of rails (at 10 kΩ) - maximizes dynamic range when driving 12-bit ADCs in 3.3 V systems. |
| Capacitive Load Drive | 500 pF - supports direct connection to long PCB traces or EMI filters without instability. |
Pinout & Package
SOT-23-14 (DYY) package: 4.20 mm × 1.90 mm, ultra-compact footprint for space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply | Highest potential rail; must be decoupled locally to suppress supply noise coupling into analog signal paths. |
| V− | Negative supply / ground | Reference node for single-supply operation; connects to system ground or negative rail in dual-supply configs. |
| OUT A, OUT B, OUT C, OUT D | Amplifier outputs | Four independent rail-to-rail outputs; each capable of sourcing/sinking ±40 mA short-circuit current. |
| –IN A to –IN D | Inverting inputs | Differential inputs for four channels; accept common-mode voltages from V− − 0.1 V to V+ − 1 V. |
| +IN A to +IN D | Non-inverting inputs | High-impedance (10 pA bias current) inputs; enable precision single-ended or differential sensing topologies. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation at –40°C to +125°C ambient, meeting automotive reliability and lifetime requirements. |
| Rail-to-rail output swing | Delivers full dynamic range into 10 kΩ loads - essential for maximizing resolution of downstream 3.3 V ADCs. |
| Resistive open-loop output impedance | 1200 Ω at 1 MHz - simplifies stability with high capacitive loads (e.g., EMI filters, long cables) without added series resistance. |
| Integrated RFI/EMI rejection filter | EMIRR+ >100 dB at 900 MHz - suppresses cellular and Bluetooth interference in infotainment head units and telematics modules. |
| No phase reversal under overdrive | Guaranteed behavior eliminates latch-up risk in transient-heavy environments like powertrain current sensing during fault events. |
Applications
| Infotainment Power Monitoring | ADAS Camera Sensor Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324QDRQ1 | Same electrical specs but in SOIC-14 (8.65 mm × 3.91 mm); 115.1°C/W RθJA vs 154.3°C/W for DYY. | Better thermal performance in high-power-density modules; larger footprint unsuitable for ultra-compact camera modules. | Choose LMV324QDRQ1 for thermally demanding applications where board area permits SOIC packaging. |
| TSV914IQDT | Wider GBW (8 MHz), higher IQ (160 µA/ch), no AEC-Q100 qualification; 1.8 V to 5.5 V supply range. | Not qualified for automotive safety-critical systems; suitable only for non-AEC-Q100 industrial or consumer designs. | Choose TSV914IQDT only for cost-sensitive non-automotive applications requiring higher speed and wider supply range. |
Compared with LMV324AQDYYRQ1, LMV324QDRQ1 offers superior thermal dissipation in larger packages but sacrifices miniaturization, while TSV914IQDT delivers higher bandwidth at the expense of automotive qualification and higher power - making LMV324AQDYYRQ1 the sole choice for space-constrained, AEC-Q100-compliant quad-amplifier roles.

FAQ
What is the maximum capacitive load the LMV324AQDYYRQ1 can drive stably?
The LMV324AQDYYRQ1 is characterized for stable operation with up to 500 pF capacitive load without external compensation. Its resistive open-loop output impedance (1200 Ω at 1 MHz) and 76° phase margin at unity gain enable robust performance even with higher capacitance when combined with appropriate series resistance - verified in TI's typical characteristics Figure 6-21.
Does the LMV324AQDYYRQ1 support true rail-to-rail input?
No - the LMV324AQDYYRQ1 features rail-to-rail *output* swing but only extends its input common-mode range to within 100 mV of V− and to V+ − 1 V. This is explicitly specified in Section 6.7 (VCM = (V−) − 0.1 V to (V+) − 1 V), and operation beyond this range may degrade CMRR or cause phase reversal.
What is the overload recovery time of the LMV324AQDYYRQ1?
The LMV324AQDYYRQ1 has an overload recovery time of 0.9 µs (900 ns), measured from saturated output to linear region entry under 5 V supply and 2-V step conditions. This value is documented in Section 6.7 Electrical Characteristics and confirmed in Figure 6-23 of the datasheet.
Is the LMV324AQDYYRQ1 pin-compatible with standard LMV324 variants?
No - the LMV324AQDYYRQ1 uses the SOT-23-14 (DYY) package, which has a unique 14-pin layout distinct from SOIC-14 or TSSOP-14 footprints. Pin functions match the LMV324A-Q1 family specification (Table 5-3), but mechanical compatibility requires dedicated DYY land pattern design.
How does the LMV324AQDYYRQ1 handle EMI in automotive environments?
The LMV324AQDYYRQ1 integrates an internal RFI/EMI rejection filter, achieving >100 dB EMIRR+ at 900 MHz (Figure 6-30). This design mitigates interference from cellular, GPS, and Bluetooth sources common in modern vehicles - a feature validated per AEC-Q100 and critical for infotainment and telematics signal integrity.
