Product details
Overview
LMV358IDRG4Q1 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 LMV358IDRG4Q1 datasheet, LMV358IDRG4Q1 pinout, LMV358IDRG4Q1 application, or LMV358IDRG4Q1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, rail-to-rail output swing down to 60 mV above GND and within 100 mV of VCC at 5 V, input common-mode range extending to ground, and guaranteed performance across automotive temperature extremes.
Technical Context
The LMV358IDRG4Q1 implements a CMOS-input, rail-to-rail output op-amp architecture optimized for single-supply operation. Its input stage supports common-mode voltages from −0.2 V to VCC + 0.2 V (at 5 V), enabling direct interfacing with grounded sensors and microcontroller ADC references.
Internally, it features matched P-channel and N-channel output transistors to achieve true rail-to-rail swing without crossover distortion. The 1-MHz gain-bandwidth product and 60° phase margin ensure stable unity-gain buffer operation with capacitive loads up to 100 pF when properly compensated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - Enables direct use with 3.3 V and 5 V automotive ECUs without level-shifting. |
| Unity-Gain Bandwidth | 1 MHz - Supports audio-frequency signal conditioning and medium-speed sensor amplification (e.g., throttle position, cabin temperature). |
| Slew Rate | 1 V/µs - Limits large-signal settling time to ≤1 µs for 1-V step inputs, suitable for non-critical timing paths. |
| Input Offset Voltage | 7 mV max (full temp range) - Determines DC accuracy in precision gain stages; requires calibration or trimming for sub-mV error budgets. |
| Supply Current per Amplifier | 210 µA typ at 25°C - Enables dual-amplifier operation in battery-sensitive modules with <500 µA total quiescent draw. |
| Rail-to-Rail Output Swing | Within 60 mV of GND and 100 mV of VCC at 5 V - Allows full dynamic range utilization into 10-kΩ loads, maximizing ADC resolution. |
| Common-Mode Input Range | −0.2 V to 4.2 V at 5 V - Permits direct connection of single-ended sensors referenced to ground or mid-supply. |
Pinout & Package
LMV358IDRG4Q1 is housed in an 8-pin SOIC (D) package with standard JEDEC outline, 1.27 mm pitch, and 6.2 mm × 5.3 mm footprint - compatible with automated SMT assembly and legacy PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | Accepts feedback or differential input signals; high-impedance CMOS node (IIB = 15 nA typ). |
| 2 | Non-Inverting Input (Amplifier A) | Connects to reference or sensor; supports input voltage down to −0.2 V relative to GND. |
| 3 | Output (Amplifier A) | Delivers rail-to-rail voltage swing; capable of sourcing 5 mA and sinking 10 mA at 5 V. |
| 4 | GND | Analog ground reference; must be tied to system power ground with low-impedance path to minimize noise coupling. |
| 5 | Non-Inverting Input (Amplifier B) | Independent input for second channel; electrically identical to Pin 2. |
| 6 | Inverting Input (Amplifier B) | Independent input for second channel; electrically identical to Pin 1. |
| 7 | Output (Amplifier B) | Independent output; shares same drive capability and swing limits as Pin 3. |
| 8 | VCC+ | Positive supply rail; accepts 2.7–5.5 V; decoupling capacitor (0.1 µF) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Grade 1 (−40°C to +125°C) - Validated for under-hood automotive environments without derating. |
| No Crossover Distortion | CMOS output stage eliminates notch distortion in Class-AB transitions - critical for low-THD audio and sensor signal fidelity. |
| Rail-to-Rail Output | Swings within 60 mV of GND and 100 mV of VCC at 5 V - maximizes usable voltage range for 10-bit+ microcontroller ADCs. |
| Ground-Sensing Inputs | Common-mode range includes 0 V - enables direct interfacing with thermistors, potentiometers, and current-sense shunts tied to GND. |
| Low Quiescent Current | 210 µA per amplifier at 25°C - supports always-on vehicle subsystems (e.g., door module wake-up circuits) with minimal battery drain. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358QDRQ1 | Same silicon, identical electrical specs, but packaged in SOIC-D with standard green RoHS finish (no G4 suffix); MSL Level-1, CU NIPDAU. | No difference in automotive functionality; differs only in tape-and-reel packaging (2500 vs 2500) and marking ("358IQ1" vs "358IQ1"). | Select LMV358QDRQ1 if standard reel packaging suffices and G4's enhanced moisture resistance is not required for your SMT process. |
| TSV912AQDRQ1 | Higher GBW (8 MHz), lower input offset (1.5 mV max), but higher supply current (820 µA per amp) and narrower supply range (2.7–5.5 V same). | Better suited for higher-speed closed-loop control (e.g., EPS torque assist) where bandwidth >1 MHz is needed; less optimal for ultra-low-power always-on nodes. | Choose TSV912AQDRQ1 when design requires faster settling or tighter DC accuracy, accepting higher quiescent power and cost. |
Compared with LMV358QDRQ1, LMV358IDRG4Q1 offers identical performance with enhanced moisture sensitivity handling (G4 suffix denotes stricter MSL compliance), while TSV912AQDRQ1 trades 4× higher supply current for 8× greater bandwidth and 4.7× lower input offset - making LMV358IDRG4Q1 optimal for cost- and power-constrained automotive signal conditioning where 1-MHz bandwidth suffices.

FAQ
What is the maximum operating junction temperature for LMV358IDRG4Q1?
The absolute maximum operating virtual junction temperature (TJ) for LMV358IDRG4Q1 is 150°C, as specified in the Absolute Maximum Ratings table. This limit ensures long-term reliability under worst-case power dissipation and ambient conditions in automotive under-hood applications. Thermal design must maintain TJ ≤ 150°C using θJA = 97°C/W for the SOIC-D package, especially at 125°C ambient and full 5.5 V supply.
Does LMV358IDRG4Q1 support single-supply operation with input signals at ground potential?
Yes, LMV358IDRG4Q1 supports true single-supply operation with input common-mode voltage range extending to −0.2 V at 5 V supply, allowing direct connection of grounded sensors (e.g., thermistors, potentiometers). Its input stage is designed for rail-to-rail common-mode operation, eliminating the need for biasing networks in most automotive sensor interfaces.
What is the output drive capability of LMV358IDRG4Q1 at 5 V supply?
At 5 V supply, LMV358IDRG4Q1 can source up to 5 mA and sink up to 10 mA while maintaining rail-to-rail output swing specifications. This drive strength supports direct interfacing with 10-kΩ ADC inputs and moderate fan-out to multiple logic inputs, though external buffers are recommended for loads exceeding 5 mA continuous.
Is LMV358IDRG4Q1 pin-compatible with industry-standard dual op-amps like LM358?
No, LMV358IDRG4Q1 is not pin-compatible with LM358. While both are dual op-amps in SOIC-8 packages, LMV358IDRG4Q1 uses standard op-amp pinout (1: A−, 2: A+, 3: AOUT, 4: GND, 5: B+, 6: B−, 7: BOUT, 8: VCC), whereas LM358 places GND on Pin 4 and VCC on Pin 8 - same physical pin locations, but LM358's input/output assignments differ (e.g., LM358 Pin 1 is AOUT, not A−). Board redesign is required for substitution.
What does the 'G4' suffix in LMV358IDRG4Q1 indicate?
The 'G4' suffix in LMV358IDRG4Q1 denotes TI's Green (RoHS & no Sb/Br) eco-plan with CU NIPDAU lead finish and Moisture Sensitivity Level (MSL) Level-1 rating (unlimited floor life at ≤30°C/60% RH). It confirms compliance with strict environmental standards and guarantees robust reflow solderability without baking, distinguishing it from standard 'Q1' variants with identical electrical specs but different packaging qualifications.
