Product details
Overview
LMV358IDDUR 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, delivering 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier. It features rail-to-rail output swing, ground-sensing input common-mode range, and operates across –40°C to 125°C - used in portable media players, HVAC sensor conditioning, and motor control feedback loops.
For engineers reviewing the LMV358IDDUR datasheet, LMV358IDDUR pinout, LMV358IDDUR application, or LMV358IDDUR equivalent, key selection criteria include its dual-channel rail-to-rail output capability, low quiescent current at 2.7 V, guaranteed operation over automotive temperature range, and compatibility with space-constrained VSSOP-8 layouts.
Technical Context
The LMV358IDDUR implements a CMOS input stage enabling rail-to-rail output swing and ground-referenced input operation. Its internal architecture supports stable unity-gain configuration with ≥60° phase margin into 2 kΩ loads and maintains >50 dB CMRR across 0–1.7 V common-mode input range at 2.7 V supply.
It operates as a true single-supply op amp without external level-shifting components: inputs accept signals down to GND, outputs swing within 180 mV of rails at 10 kΩ load (2.7 V), and exhibits no crossover distortion due to complementary output stage design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into Li-ion battery-powered systems and 3.3 V logic domains. |
| Unity-Gain Bandwidth | 1 MHz - supports audio pre-amplification, sensor signal buffering, and medium-speed closed-loop control up to ~100 kHz. |
| Slew Rate | 1 V/μs - ensures faithful reproduction of 100 kHz full-scale sine waves without slew-induced distortion. |
| Input Offset Voltage | 7 mV typ (25°C) - suitable for non-precision DC-coupled applications like level shifting and basic comparators. |
| Supply Current per Amp | 210 μA typ at 2.7 V - allows dual-channel amplification in always-on subsystems with sub-500 μA total quiescent budget. |
| Common-Mode Input Range | 0 V to VCC – 1.0 V - permits direct interfacing with ground-referenced sensors (e.g., thermistors, RTDs) without biasing resistors. |
| Output Swing (RL = 10 kΩ) | Within 180 mV of rails at 2.7 V - maximizes dynamic range in low-voltage ADC driver and DAC output buffer roles. |
Pinout & Package
The LMV358IDDUR is housed in an 8-pin VSSOP package (3.00 mm × 3.00 mm body size), optimized for high-density PCB layouts and thermal performance (RθJA = 210°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output of Amplifier 1 | Delivers rail-to-rail buffered or amplified signal; requires local decoupling when driving capacitive loads >100 pF. |
| 1IN– | Inverting Input of Amplifier 1 | Accepts feedback network connection; referenced to GND or virtual ground in standard configurations. |
| 1IN+ | Noninverting Input of Amplifier 1 | Receives input signal directly or via high-impedance sensor interface; supports DC-coupled ground-referenced sources. |
| GND | Negative Supply Terminal | System ground reference; must be low-impedance and shared with analog/digital return paths to minimize noise coupling. |
| VCC+ | Positive Supply Terminal | Connects to regulated 2.7–5.5 V supply; requires 0.1 μF ceramic capacitor placed ≤2 mm from pin. |
| 2OUT | Output of Amplifier 2 | Independent output channel; usable for dual-path signal processing or redundant monitoring functions. |
| 2IN– | Inverting Input of Amplifier 2 | Configurable for inverting gain stages, active filters, or current-to-voltage conversion with photodiode sensors. |
| 2IN+ | Noninverting Input of Amplifier 2 | Enables noninverting amplification, voltage followers, or summing configurations with multiple inputs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables maximum signal utilization in 3.3 V or lower systems - e.g., drives SAR ADCs with full-scale input range without level-shifting circuitry. |
| Ground-sensing input range | Eliminates need for input biasing networks when interfacing with 0–VREF sensors (e.g., bridge-based pressure transducers). |
| No crossover distortion | Ensures clean small-signal amplification in audio line drivers and precision instrumentation front-ends where THD < 0.1% is critical. |
| –40°C to 125°C operation | Qualified for under-hood automotive modules, industrial motor drives, and outdoor HVAC controllers without derating. |
| ESD protection (HBM) | 2000-V Human-Body Model rating reduces risk of field failure during handling and board assembly in uncontrolled environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Same electrical specs; SOIC-8 package (8.65 mm × 3.91 mm) - 3× larger footprint than VSSOP-8. | Preferred for prototyping, manual soldering, or legacy board designs with SOIC footprints. | Select LMV358IDR when board real estate is not constrained and hand assembly is required. |
| TLV2372IDR | Lower input bias current (1 pA vs 250 nA), higher GBW (2.4 MHz), but higher supply current (1 mA vs 210 μA) and narrower temp range (–40°C to 125°C same). | Better for high-impedance pH sensors or precision integrators; less suitable for ultra-low-power battery operation. | Choose TLV2372IDR only when femtoampere input bias or >1 MHz bandwidth is mandatory - otherwise LMV358IDDUR offers superior power efficiency. |
Compared with LMV358IDR, LMV358IDDUR saves >70% PCB area while maintaining identical performance; versus TLV2372IDR, it reduces quiescent current by 80% at the cost of 2.4× lower bandwidth - making it optimal for cost-sensitive, space-constrained, always-on sensor nodes.

FAQ
What is the maximum operating temperature range for the LMV358IDDUR?
The LMV358IDDUR is specified for continuous operation from –40°C to +125°C ambient temperature, meeting automotive AEC-Q100 Grade 1 requirements. This makes it suitable for under-hood engine control units, industrial motor drives, and outdoor HVAC equipment where thermal robustness is essential. The device maintains full electrical performance across this range without derating.
Does the LMV358IDDUR support single-supply operation with input signals referenced to ground?
Yes, the LMV358IDDUR supports true single-supply operation with input common-mode voltage range extending to GND (0 V). Its input stage accepts signals from 0 V up to VCC – 1.0 V, enabling direct connection to ground-referenced sensors such as thermistors, RTDs, and bridge transducers without external biasing networks - reducing component count and layout complexity.
What is the typical supply current consumption of the LMV358IDDUR at 2.7 V?
The LMV358IDDUR draws 210 μA typical supply current per amplifier at 2.7 V and 25°C, resulting in ~420 μA total for both channels. This ultra-low quiescent current enables use in battery-powered applications such as portable medical monitors and wireless sensor nodes where multi-year operation from coin cells is required without compromising bandwidth or output drive capability.
Can the LMV358IDDUR drive capacitive loads, and what is the recommended compensation strategy?
The LMV358IDDUR can drive capacitive loads up to 100 pF stably in unity-gain configuration without external compensation. For loads >100 pF, TI recommends adding a series resistor (typically 20–100 Ω) between the output pin and the capacitive load to isolate the op amp's output stage from the reactive impedance - preventing peaking and oscillation while preserving signal integrity in ADC driver and filter applications.
Is the LMV358IDDUR pin-compatible with other members of the LMV3xx family?
Yes, the LMV358IDDUR shares identical pinout with all LMV358 variants in VSSOP-8 (DDU/DGK) and TSSOP-8 (PW) packages, including LMV358IDR (SOIC-8) except for physical package differences. Pin functions - 1OUT, 1IN–, 1IN+, GND, VCC+, 2OUT, 2IN–, 2IN+ - are fully consistent across these variants, allowing drop-in replacement during design iteration or manufacturing substitution without PCB changes.
