Product details
Overview
LMV358MM/NOPB 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 gain-bandwidth product, 1 V/µs slew rate, and 210 µA typical supply current per amplifier. It delivers rail-to-rail output swing (V+ −10 mV / V− +65 mV at 10 kΩ), −0.2 V to V+−0.8 V input common-mode range including ground, and operates across −40°C to +125°C - enabling use in battery-powered sensor signal conditioning and portable analog front-ends.
For engineers reviewing the LMV358MM/NOPB datasheet, LMV358MM/NOPB pinout, LMV358MM/NOPB application, or LMV358MM/NOPB equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for cost-sensitive, space-constrained industrial and consumer designs requiring stable low-voltage op amp performance.
Technical Context
The LMV358MM/NOPB implements a bipolar-input, rail-to-rail output architecture built on Texas Instruments' submicron BiCMOS process, delivering improved noise performance and higher output drive versus CMOS-input alternatives. Its input stage supports common-mode voltage down to −0.2 V (enabling ground-referenced sensing), while the output stage achieves V+ −10 mV high-side and V− +65 mV low-side swing into 10 kΩ loads.
It is internally compensated for unity-gain stability with up to 200 pF capacitive load, exhibits no crossover distortion in follower configurations, and maintains 60° phase margin and 10 dB gain margin at 5 V supply - making it suitable for active filters, transimpedance amplifiers, and precision buffer stages without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports full operation across depleted Li-ion (3.0 V) and regulated 3.3 V/5 V rails without brownout. |
| Gain-Bandwidth Product | 1 MHz - enables stable unity-gain buffering and first-order active filtering up to ~100 kHz with predictable roll-off. |
| Slew Rate | 1 V/µs - sufficient for 100 kHz sine waves at 10 Vpp without distortion; limits large-signal settling time to ~10 µs. |
| Input Offset Voltage | 1.7 mV (max) - contributes ≤0.34% error in 500 mV full-scale sensor interfaces; drift of 5 µV/°C minimizes thermal drift. |
| Rail-to-Rail Output Swing | V+ −10 mV / V− +65 mV @ 10 kΩ - maximizes dynamic range in 3.3 V systems (e.g., 0–3.29 V usable output span). |
| Input Common-Mode Range | −0.2 V to V+ −0.8 V - allows direct DC-coupled sensing of signals referenced to ground in single-supply configurations. |
| Quiescent Current | 210 µA (typ, both amps) - enables >1-year battery life in always-on 10 µA sleep-mode systems with periodic analog wake-up. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm pitch, thin-profile surface-mount design optimized for space-constrained PCBs in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN A− | Inverting input of amplifier A - connects to feedback network in inverting configurations or reference node in comparators. |
| 2 | V− | Negative supply terminal - tied to GND in single-supply operation; must be decoupled with 0.1 µF ceramic capacitor. |
| 3 | IN A+ | Noninverting input of amplifier A - accepts sensor, reference, or signal source; supports common-mode down to −0.2 V. |
| 4 | OUT A | Output of amplifier A - drives loads up to 10 kΩ directly; requires series resistor for >200 pF capacitive loads to ensure stability. |
| 5 | OUT B | Output of amplifier B - electrically isolated from OUT A; shares same supply pins but has independent small-signal path. |
| 6 | IN B− | Inverting input of amplifier B - used for second signal path; layout symmetry recommended to minimize crosstalk (< −80 dB @ 1 kHz). |
| 7 | IN B+ | Noninverting input of amplifier B - identical electrical specs to IN A+; supports separate biasing for differential or dual-channel sensing. |
| 8 | V+ | Positive supply terminal - accepts 2.7–5.5 V; requires local 0.1 µF + 1 µF decoupling between V+ and V− near the package. |
Key Features
| Feature | Design Value |
|---|---|
| No Crossover Distortion | Eliminates dead-zone nonlinearity in unity-gain buffers - critical for audio line drivers and precision DC-coupled signal chains. |
| Rail-to-Rail Output | Delivers full 3.29 Vpp swing on 3.3 V supply - preserves ADC resolution and avoids clipping in low-voltage data acquisition. |
| Ground-Sensing Input | Accepts inputs down to −0.2 V - enables direct interfacing with 0 V-referenced thermistors, current shunts, or bridge sensors. |
| Low Power Consumption | 210 µA total quiescent current - reduces thermal load in sealed enclosures and extends runtime in coin-cell–powered IoT nodes. |
| Industrial Temp Range | −40°C to +125°C operation - qualified for under-hood automotive modules, industrial PLC I/O, and outdoor environmental sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage rail-to-rail output op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Same silicon die, SOIC-8 package (4.90 mm × 3.91 mm); 207.9°C/W θJA vs 235°C/W for VSSOP-8. | Better thermal dissipation in high-ambient industrial environments; larger footprint less suitable for wearables or ultra-compact PCBs. | Select LMV358IDR when board space permits and thermal margin is critical above 85°C ambient. |
| MCP6022-E/SN | CMOS input (0.1 pA IB), 10 MHz GBWP, 3.5 V/µs slew rate; higher supply current (1 mA per amp) and narrower VCM (0.3 V to V+−0.7 V). | Superior for high-impedance pH or photodiode sensors; unsuitable for ground-referenced inputs or ultra-low-power battery operation. | Choose MCP6022-E/SN only when femtoampere bias current or multi-MHz bandwidth is required - not a drop-in replacement. |
Compared with LMV358MM/NOPB, LMV358IDR offers better thermal performance in SOIC packaging but sacrifices board-area efficiency, while MCP6022-E/SN trades off power and ground-sensing capability for higher speed and lower input bias - making LMV358MM/NOPB optimal for cost-sensitive, space-constrained, ground-referenced low-voltage analog signal chains.

FAQ
What is the maximum capacitive load the LMV358MM/NOPB can drive without external compensation?
The LMV358MM/NOPB is unity-gain stable and can directly drive up to 200 pF capacitive load without oscillation or excessive ringing, as verified in TI's SNOS012K datasheet Figure 7-23. For loads exceeding 200 pF - such as LCD panel lines or long PCB traces - a series isolation resistor (e.g., 620 Ω) between the LMV358MM/NOPB output and the capacitance restores phase margin. This configuration preserves DC accuracy while ensuring stable step response in applications like display biasing or piezo actuator control.
Does the LMV358MM/NOPB support true single-supply operation with input signals at ground potential?
Yes, the LMV358MM/NOPB supports true single-supply operation with input common-mode voltage down to −0.2 V (relative to V−), explicitly enabling direct connection of ground-referenced sources like resistive temperature detectors (RTDs), current-sense shunts, or bridge sensors. The input stage includes protection diodes; however, sustained input voltages below −0.3 V require external clamping. This capability eliminates level-shifting circuitry in 3.3 V sensor interfaces, reducing BOM count and layout complexity in the LMV358MM/NOPB-based design.
How does the LMV358MM/NOPB compare to the legacy LM358 in low-voltage operation?
The LMV358MM/NOPB is the low-voltage optimized successor to the LM358, specified for reliable operation from 2.7 V to 5.5 V - whereas the LM358 requires minimum 3 V and degrades significantly below 5 V. At 3.3 V, the LMV358MM/NOPB maintains full rail-to-rail output swing (V+ −10 mV), 1 MHz GBWP, and 210 µA supply current, while the LM358 exhibits reduced output drive, increased VOS, and no rail-to-rail capability. TI confirms LMV358MM/NOPB specifications meet or exceed LM358 benchmarks across the 2.7–5.5 V range.
What is the thermal resistance (θJA) of the LMV358MM/NOPB in its VSSOP-8 package?
The LMV358MM/NOPB in the VSSOP-8 (DGK) package has a junction-to-ambient thermal resistance (θJA) of 235°C/W under standard JEDEC 2S2P test conditions, as documented in Section 7.5 of the SNOS012K datasheet. This value assumes a two-layer PCB with 1 oz copper and minimal copper pour. With proper thermal vias and 2-in² copper area, actual θJA can improve to ~120°C/W - allowing continuous operation at 85°C ambient with ≤15 mW dissipation. Always verify thermal performance in the final LMV358MM/NOPB layout using IR imaging or simulation.
Is the LMV358MM/NOPB suitable for automotive applications?
The LMV358MM/NOPB is the commercial-grade version and is not AEC-Q100 qualified. For automotive use, TI offers the LMV358QDRQ1 (AEC-Q100 Grade 1, −40°C to +125°C) and LMV358QDRQ3 (Grade 3, −40°C to +85°C) in SOIC-8, or LMV358QM8X (Grade 1) in VSSOP-8. These variants undergo additional stress testing, have controlled parametric distributions, and include automotive-specific failure reporting. Do not substitute LMV358MM/NOPB in safety-critical or engine-compartment automotive systems without formal qualification review.
