Product details
Overview
LMV358QDDURG4 from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 5.5 V) single-supply operation, featuring 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier. It delivers rail-to-rail output swing, ground-sensing input common-mode range, and operates across –40°C to 125°C - used in motor control feedback loops, portable media player audio stages, and HVAC sensor signal conditioning.
For engineers reviewing the LMV358QDDURG4 datasheet, LMV358QDDURG4 pinout, LMV358QDDURG4 application, or LMV358QDDURG4 equivalent, key selection criteria include its dual-channel rail-to-rail output capability, guaranteed operation at 2.7 V, thermal performance in VSSOP-8 packaging, and compatibility with space-constrained industrial and consumer designs requiring low quiescent current and wide temperature support.
Technical Context
The LMV358QDDURG4 implements a CMOS input stage enabling rail-to-rail output swing and ground-referenced input operation, with a 1-MHz unity-gain bandwidth and 1-V/μs slew rate ensuring stable small-signal amplification up to audio frequencies. Its input offset voltage is specified at 7 mV (typ), with 5 μV/°C drift and 63 dB CMRR at 2.7 V.
It operates as a true single-supply op amp: the input common-mode range extends from –0.2 V to VCC – 1.0 V, and output swings within 180 mV of each rail under 10-kΩ load at 2.7 V. No shutdown functionality is present - unlike the LMV324S variant, this dual amplifier lacks enable/disable control pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct integration into 3.3-V and 5-V systems without level-shifting. |
| Unity-Gain Bandwidth | 1 MHz - enables stable closed-loop gain ≥1 up to ~1 MHz, suitable for audio preamps and sensor signal conditioning. |
| Slew Rate | 1 V/μs - limits full-power bandwidth to ~160 kHz at 10-Vpp output, sufficient for DC–audio applications. |
| Input Offset Voltage | 7 mV (typ) - introduces ≤7-mV DC error in precision DC-coupled paths; compensated via external trimming if needed. |
| Supply Current per Amp | 210 μA (typ) at 2.7 V - enables battery-powered operation with multi-day runtime in low-duty-cycle sensing nodes. |
| Output Swing (RL = 10 kΩ) | Within 180 mV of rails at 2.7 V - maximizes dynamic range in low-voltage ADC driver or comparator reference circuits. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and high-reliability embedded control environments. |
Pinout & Package
The LMV358QDDURG4 is housed in an 8-pin VSSOP package (DGK) measuring 3.0 mm × 3.0 mm, with 0.65-mm lead pitch and exposed thermal pad for enhanced power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 10 mA; rail-to-rail swing enables full utilization of ADC input range. |
| 2 | IN– A | Inverting input of Amplifier A - accepts signals down to –0.2 V, supporting ground-referenced differential configurations. |
| 3 | IN+ A | Noninverting input of Amplifier A - high-impedance CMOS node; bias current <250 nA minimizes resistor-induced offset. |
| 4 | GND | Analog ground reference - must be tied directly to low-impedance system ground plane to maintain PSRR and noise immunity. |
| 5 | IN+ B | Noninverting input of Amplifier B - electrically isolated from Channel A; enables independent dual-path signal processing. |
| 6 | IN– B | Inverting input of Amplifier B - shares same input specs as Pin 2; supports matched dual feedback networks. |
| 7 | OUT B | Amplifier B output - identical AC/DC performance to Pin 1; allows simultaneous buffering and inversion in one package. |
| 8 | VCC+ | Positive supply - accepts 2.7–5.5 V; bypass capacitor (0.1 μF ceramic) required at pin for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range at 2.7 V supply - eliminates need for negative rail or level-shifting in single-supply data acquisition. |
| Ground-sensing input range | Accepts inputs down to –0.2 V - enables direct interfacing with 0-V referenced sensors (e.g., thermistors, bridge transducers). |
| Low 210-μA supply current | Reduces thermal load and extends battery life in always-on IoT endpoints and portable instrumentation. |
| –40°C to +125°C operation | Qualified for extended temperature industrial and automotive under-hood applications without derating. |
| No crossover distortion | CMOS output stage ensures clean zero-crossing in AC-coupled audio and precision waveform generation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | SOIC-8 package (8.65 × 3.91 mm); same electrical specs but larger footprint and higher RθJA (97°C/W vs 172°C/W). | Preferred for prototyping or through-hole assembly; unsuitable for ultra-compact PCBs where VSSOP-8 is mandated. | Select LMV358IDR only when board space permits SOIC and thermal margin exceeds 40°C/W. |
| TLV2372IDR | Lower 55-μA supply current, 3-MHz GBW, but narrower –40°C to 125°C temp range limited to 105°C max junction. | Better for battery longevity and higher-bandwidth filtering; not qualified for full automotive under-hood thermal stress. | Choose TLV2372IDR when >1-MHz bandwidth is required and operating ambient stays below 85°C. |
Compared with LMV358IDR, the LMV358QDDURG4 saves >70% board area and improves thermal resistance by 76°C/W - critical for sealed enclosures. Versus TLV2372IDR, it trades bandwidth and quiescent current for guaranteed 125°C operation and robustness in thermally aggressive industrial settings.

FAQ
What is the maximum supply voltage for LMV358QDDURG4?
The absolute maximum supply voltage for LMV358QDDURG4 is 5.5 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. Recommended operating range is 2.7 V to 5.5 V, with full electrical performance guaranteed across that span - including rail-to-rail output swing and –40°C to +125°C operation.
Does LMV358QDDURG4 support dual-supply operation?
Yes, LMV358QDDURG4 supports dual-supply operation (e.g., ±2.5 V), though it is optimized for single-supply use from 2.7 V to 5.5 V. When operated on dual supplies, the input common-mode range extends from –0.2 V to VCC+ – 1.0 V, and output swing remains rail-to-rail relative to the chosen supply rails. No modifications or external components are required for dual-supply configuration.
Is LMV358QDDURG4 pin-compatible with standard LM358?
No, LMV358QDDURG4 is not pin-compatible with the legacy LM358. While both are dual op amps, LMV358QDDURG4 uses an 8-pin VSSOP (DGK) package with different pin assignments - notably GND on Pin 4 and VCC+ on Pin 8 - whereas LM358 uses an 8-pin SOIC with GND on Pin 4 and VCC+ on Pin 8 but incompatible internal routing and rail-to-rail architecture. PCB redesign is required for migration.
What is the input bias current specification for LMV358QDDURG4?
The input bias current for LMV358QDDURG4 is 250 nA (maximum) at 25°C and 2.7 V supply, with a typical value of 11 nA. This low bias current minimizes voltage drop across high-value feedback resistors, preserving accuracy in high-impedance sensor interfaces such as thermistor networks or photodiode transimpedance amplifiers.
Can LMV358QDDURG4 drive a 600-Ω load effectively?
LMV358QDDURG4 can source/sink up to 10 mA (typical short-circuit current), making it capable of driving a 600-Ω load at ±2.5 V output swing - i.e., up to ~4.2 Vpp into 600 Ω. However, output swing degrades under heavy load: at 2.7 V supply and RL = 600 Ω, high-level output drops to ~VCC – 400 mV. For full rail-to-rail performance, keep loads ≥2 kΩ or add external buffer stage.
