Product details
Overview
LMV358QDRG4Q1 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 LMV358QDRG4Q1 datasheet, LMV358QDRG4Q1 pinout, LMV358QDRG4Q1 application, or LMV358QDRG4Q1 equivalent, key selection criteria include rail-to-rail output swing at low supply voltage, automotive temperature qualification, input common-mode range including ground, and compatibility with space-constrained SOIC-8 layouts in safety-critical analog front-ends.
Technical Context
The LMV358QDRG4Q1 implements a CMOS-input, rail-to-rail output op-amp architecture optimized for single-supply operation. Its input stage supports common-mode voltages down to ground (−0.2 V at 5 V supply), enabling direct interfacing with resistive sensors and DAC outputs without level-shifting.
It delivers stable unity-gain performance with ≥60° phase margin into 2 kΩ loads and exhibits no crossover distortion across its full output swing - critical for precision DC-coupled amplification and active filtering in automotive subsystems.
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 microcontroller rails without LDO regulation. |
| Unity-Gain Bandwidth | 1 MHz - supports audio-band filtering, sensor signal conditioning, and closed-loop response up to ~100 kHz with adequate phase margin. |
| Slew Rate | 1 V/µs - sufficient for 100 kHz sine waves at 16 Vpp without distortion; limits large-signal settling time to ~1 µs for 1 V step. |
| Input Offset Voltage | 7 mV max (typ 1.7 mV) - defines DC accuracy in non-inverting gain configurations; impacts offset error in 12-bit ADC front-ends. |
| Rail-to-Rail Output Swing | VOL = 60 mV, VOH = VCC − 100 mV (RL = 10 kΩ) - delivers >98% of full-scale dynamic range at 3.3 V supply, maximizing SNR in low-voltage systems. |
| Supply Current | 210 µA typ per amplifier - enables dual-channel amplification in always-on modules with sub-500 µA total quiescent budget. |
| Operating Temperature | −40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and powertrain applications. |
Pinout & Package
LMV358QDRG4Q1 is housed in an 8-pin SOIC (D) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). The package supports automated optical inspection and reflow soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives feedback network or load; rail-to-rail swing enables full utilization of ADC reference range. |
| 2 | IN−1 | Inverting input of Amp1 - connects to feedback resistor or sensor bridge leg; high impedance (>1012 Ω) minimizes loading on high-Z sources. |
| 3 | IN+1 | Non-inverting input of Amp1 - accepts sensor, DAC, or reference voltage; common-mode range includes ground for single-supply biasing. |
| 4 | GND | Analog ground reference - must be tied to system AGND plane; separate from digital ground except at single-point star connection. |
| 5 | IN+2 | Non-inverting input of Amp2 - independent channel for second sensor or signal path; no crosstalk between amplifiers (≥120 dB @ 1 kHz). |
| 6 | IN−2 | Inverting input of Amp2 - used for differential sensing or active filter configuration; matched input bias current reduces offset drift. |
| 7 | OUT2 | Amplifier 2 output - provides second independent gain stage; identical AC/DC specs to OUT1 for matched channel performance. |
| 8 | VCC+ | Positive supply rail - decoupling capacitor (100 nF X7R) required within 5 mm of pin to suppress high-frequency noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| No Crossover Distortion | Eliminates 2nd-harmonic artifacts in Class-AB output stage, preserving THD+N < 0.1% at 1 kHz for audio and sensor signal chains. |
| Rail-to-Rail Output Swing | Delivers usable output headroom down to 60 mV above GND and within 100 mV of VCC, maximizing dynamic range in 3.3 V systems. |
| Ground-Sensing Input Range | Common-mode voltage extends to −0.2 V (at 5 V supply), enabling direct interface with grounded thermistors and current-sense shunts. |
| Automotive Qualification | AEC-Q100 Grade 1 certified (−40°C to +125°C), with production test coverage per automotive reliability standards. |
| Low Quiescent Current | 210 µA per amplifier allows dual-channel operation in battery-backed modules with multi-year standby life. |

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 die and electrical specs; differs only in tape-and-reel packaging (no G4 suffix) and RoHS finish (CU NIPDAU vs CU SN). | No functional difference; identical performance and qualification in automotive environments. | Select LMV358QDRQ1 when standard RoHS-compliant finish suffices and G4 green (Br/Sb-free) requirement is not mandated. |
| TSV912IQDRQ1 | Higher GBW (8 MHz), lower VIO (1.5 mV max), but higher IQ (820 µA) and narrower VCC range (2.7–5.5 V same). | Better for high-speed filtering or precision instrumentation; unsuitable for ultra-low-power always-on nodes. | Choose TSV912IQDRQ1 when bandwidth or offset accuracy outweighs quiescent current constraints. |
Compared with LMV358QDRQ1, LMV358QDRG4Q1 offers identical analog performance with enhanced environmental compliance (Br/Sb-free); versus TSV912IQDRQ1, it trades bandwidth and offset for 74% lower supply current - critical for battery-sensitive automotive modules.

FAQ
What is the maximum operating junction temperature for LMV358QDRG4Q1?
The absolute maximum operating virtual junction temperature (TJ) for LMV358QDRG4Q1 is 150°C, as specified in the Absolute Maximum Ratings table. This limit ensures robust thermal margin under worst-case ambient (125°C) and power dissipation conditions in automotive under-hood environments. Derating curves in the datasheet confirm reliable operation up to this junction temperature when PCB layout adheres to recommended copper pour guidelines.
Does LMV358QDRG4Q1 support single-supply operation with input signals at ground potential?
Yes, LMV358QDRG4Q1 supports true single-supply operation with input common-mode voltage extending to −0.2 V (at VCC = 5 V) and 0 V (at VCC = 2.7 V), enabling direct interfacing with grounded sensors like NTC thermistors or current-sense shunts without external level-shifting circuitry. This feature is explicitly validated across the full −40°C to +125°C temperature range.
What is the output short-circuit current capability of LMV358QDRG4Q1?
LMV358QDRG4Q1 provides ±10 mA minimum short-circuit output current (sinking and sourcing) at VCC = 5 V and TA = 25°C, with guaranteed operation up to ±5 mA across the full automotive temperature range. This allows direct driving of small capacitive loads or LED indicators without external buffers, while internal current limiting protects the device during fault conditions.
Is LMV358QDRG4Q1 pin-compatible with industry-standard dual op-amps like LM358?
No, LMV358QDRG4Q1 is not pin-compatible with LM358. While both are dual op-amps in SOIC-8 packages, LMV358QDRG4Q1 uses standard op-amp pinout (OUT1, IN−1, IN+1, GND, IN+2, IN−2, OUT2, VCC+), whereas LM358 places VCC+ at pin 8 and GND at pin 4 - matching LMV358QDRG4Q1. However, LM358 lacks rail-to-rail output and automotive qualification, making direct substitution invalid without circuit validation.
What packaging and environmental compliance does LMV358QDRG4Q1 meet?
LMV358QDRG4Q1 is supplied in a green (RoHS & no Sb/Br), lead-free SOIC-8 package with CU NIPDAU finish and JEDEC MSL Level-1 rating (260°C peak reflow). It complies with AEC-Q100 Grade 1, RoHS Directive 2011/65/EU, and TI's corporate green initiative - confirmed by TI's Package Option Addendum and material declarations.
