Product details
Overview
LMV358QDRQ1 from Texas Instruments is a dual, rail-to-rail output operational amplifier qualified for automotive applications (−40°C to 125°C), operating from 2.7 V to 5.5 V supply, with 1 MHz unity-gain bandwidth, 1 V/µs slew rate, and 210 µA typical supply current per amplifier. It serves as a low-voltage signal conditioning and sensor interface IC in engine control units and body electronics.
For engineers reviewing the LMV358QDRQ1 datasheet, LMV358QDRQ1 pinout, LMV358QDRQ1 application, or LMV358QDRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, rail-to-rail output swing (within 10 mV of rails at 10 kΩ load), input common-mode range extending to ground, and compatibility with 2.7-V single-supply systems in space-constrained automotive modules.
Technical Context
The LMV358QDRQ1 implements a CMOS-input, rail-to-rail output op-amp architecture optimized for low-voltage operation. Its input stage supports common-mode voltages down to ground, enabling direct interfacing with sensors and ADCs referenced to system ground.
It delivers stable unity-gain performance with ≥60° phase margin across temperature and supply voltage (2.7 V–5.5 V), and maintains rail-to-rail output swing under loads ≥2 kΩ - critical for driving analog inputs in automotive microcontrollers without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 5.5 V - enables direct integration into 3.3-V and 5-V automotive subsystems without regulators. |
| Unity-Gain Bandwidth | 1 MHz - supports signal conditioning for low-frequency sensor outputs (e.g., thermistors, potentiometers) up to ~100 kHz closed-loop. |
| Slew Rate | 1 V/µs - sufficient for <100 kHz full-power sine waves at 1-Vpp output, avoiding distortion in active filters and comparators. |
| Input Offset Voltage | 7 mV max (typ 1.7 mV) - ensures ≤0.7% gain error in 100-mV full-scale sensor amplification without trimming. |
| Supply Current | 210 µA typ per amplifier - allows dual-channel operation in battery-sensitive modules with sub-500-µA total quiescent draw. |
| Rail-to-Rail Output | Swings within 10 mV of VCC and GND at 10 kΩ - eliminates need for negative supply or level shifters when interfacing with 3.3-V ADCs. |
| Common-Mode Input Range | Includes ground (−0.2 V to VCC − 1.0 V) - accepts 0-V referenced signals such as current-sense shunt voltages. |
Pinout & Package
LMV358QDRQ1 is housed in an 8-pin SOIC (D) package with standard pinout and 1.27-mm pitch, compatible with automated assembly and IPC-7351B footprint D_300X190X100.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream stages with rail-to-rail swing and 60 mA short-circuit capability. |
| 2 | IN− A | Inverting input of amplifier A - high-impedance CMOS node (IIB = 15 nA typ) for precision feedback networks. |
| 3 | IN+ A | Non-inverting input of amplifier A - accepts DC-coupled sensor signals down to ground potential. |
| 4 | GND | Analog ground reference - must be tied to system ground plane; separates noise-sensitive analog return from digital power return. |
| 5 | IN+ B | Non-inverting input of amplifier B - electrically isolated from amplifier A; supports dual independent signal paths. |
| 6 | IN− B | Inverting input of amplifier B - shares same input bias characteristics as pin 2; used for differential or inverting configurations. |
| 7 | OUT B | Amplifier B output - identical AC/DC performance to pin 1; enables dual-channel functions like active filtering + buffering. |
| 8 | VCC+ | Positive supply - accepts 2.7–5.5 V; requires local 100-nF ceramic decoupling placed ≤5 mm from pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Rated for automotive temperature range (−40°C to +125°C) with stress testing per Grade 1 requirements - suitable for under-hood and cabin ECU use. |
| No Crossover Distortion | CMOS input stage eliminates crossover notch in Class-AB output stage - preserves signal fidelity in audio and sensor signal chains. |
| Rail-to-Rail Output | Delivers full dynamic range to 3.3-V ADCs without external level-shifting components - reduces BOM count and PCB area. |
| Low Supply Current | 210 µA typ per amplifier enables always-on sensor monitoring in wake-up circuits with <500-µA total system quiescent current. |
| Ground-Sensing Inputs | Input common-mode range includes 0 V - allows direct amplification of shunt-based current measurements and thermistor bridges referenced to ground. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358DR | Industrial-grade (−40°C to 85°C); identical electrical specs but not AEC-Q100 qualified. | Not approved for automotive safety-critical or under-hood use; limited to infotainment or non-safety body modules. | Select when automotive qualification is unnecessary and cost sensitivity is higher. |
| TSV912IDT | Higher GBW (8 MHz), lower input offset (1.5 mV typ), but higher supply current (820 µA typ) and no AEC-Q100 certification. | Overqualified for basic sensor buffering; unsuitable for low-quiescent designs or automotive qualification requirements. | Choose only if bandwidth >1 MHz is required and automotive qualification is handled elsewhere in the signal chain. |
Compared with LMV358DR and TSV912IDT, the LMV358QDRQ1 uniquely balances AEC-Q100 compliance, ultra-low quiescent current, and rail-to-rail output in a standard SOIC package - making it the optimal choice for cost-sensitive, thermally demanding automotive signal conditioning where qualification and power efficiency are mandatory.

FAQ
What is the operating temperature range for LMV358QDRQ1?
The LMV358QDRQ1 is qualified for automotive applications with an operating free-air temperature range of −40°C to +125°C, as defined by its Q-suffix grade and AEC-Q100 Grade 1 compliance. This range is verified per TI's production test conditions and applies across the full 2.7-V to 5.5-V supply voltage range. The device maintains specified electrical performance-including input offset voltage, bandwidth, and output swing-throughout this extended thermal envelope.
Does LMV358QDRQ1 support rail-to-rail input operation?
The LMV358QDRQ1 features rail-to-rail *output* swing but does *not* support rail-to-rail *input*. Its common-mode input voltage range extends from −0.2 V below ground to VCC − 1.0 V, meaning it accepts signals down to ground (0 V) but cannot reliably process inputs at the positive rail (VCC). For true rail-to-rail input capability, consider alternatives such as the TLV9002 or OPA333 - though neither carries AEC-Q100 qualification like the LMV358QDRQ1.
What is the maximum capacitive load the LMV358QDRQ1 can drive without instability?
Per TI's SLOS415E datasheet Figure 6–9, the LMV358QDRQ1 remains stable with capacitive loads up to 100 pF when driving a 2-kΩ load in unity-gain configuration. At 500 pF, overshoot exceeds 25%, indicating marginal stability. For loads >100 pF, a series resistor (≥100 Ω) must be added between the output and capacitor to isolate the reactive load and preserve phase margin - a standard practice documented in TI's "Stability Analysis of Op Amps" application report SLOA020.
Is LMV358QDRQ1 pin-compatible with LM358QPWRQ1?
No, LMV358QDRQ1 is not pin-compatible with LM358QPWRQ1. LMV358QDRQ1 uses an 8-pin SOIC (D) package with standard dual-op-amp pinout (pins 1–4 for Amp A, pins 5–8 for Amp B). LM358QPWRQ1 is a TSSOP-8 (PW) variant of the legacy bipolar LM358 - while pinout matches, its input stage (bipolar vs. CMOS), supply current (700 µA vs. 210 µA), and input common-mode range (0 V to VCC − 1.5 V vs. −0.2 V to VCC − 1.0 V) differ significantly. Direct replacement is not recommended without circuit validation.
Can LMV358QDRQ1 be used in single-supply 3.3-V systems?
Yes, LMV358QDRQ1 is explicitly designed for single-supply operation from 2.7 V to 5.5 V, including 3.3-V systems. At VCC = 3.3 V, it delivers rail-to-rail output swing (within 100 mV of 0 V and 3.3 V at 10 kΩ), maintains 1-MHz bandwidth, and draws only 210 µA per amplifier. Its input common-mode range includes ground, allowing direct connection to 0-V-referenced sensors - making it ideal for 3.3-V automotive microcontroller peripheral interfacing.
