Product details
Overview
LMV358Q3MMX/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 in automotive and industrial systems. It delivers 1 MHz gain-bandwidth, 1 V/µs slew rate, 210 µA supply current per amplifier, −0.2 V to V+−0.8 V input common-mode range, and rail-to-rail output swing (V+−10 mV / V−+65 mV at 10 kΩ) - enabling precision signal conditioning in battery-powered sensor interfaces and portable control circuits.
For engineers reviewing the LMV358Q3MMX/NOPB datasheet, LMV358Q3MMX/NOPB pinout, LMV358Q3MMX/NOPB application, or LMV358Q3MMX/NOPB equivalent, key selection considerations include its AEC-Q100 Grade 3 qualification (−40°C to +85°C), VSSOP-8 package footprint, guaranteed 2.7-V operation, absence of crossover distortion, and compatibility with ground-referenced inputs in single-supply configurations.
Technical Context
The LMV358Q3MMX/NOPB implements a bipolar-input, bipolar-output architecture on Texas Instruments' submicron BiCMOS process, delivering improved noise performance and higher output drive versus CMOS-input alternatives. Its input stage includes ground-sensing capability and internal ESD protection aligned with AEC-Q100-002 HBM (±900 V).
It operates as a unity-gain stable voltage amplifier with no external compensation required. The device supports capacitive loads up to 200 pF directly and maintains ≥60° phase margin under typical conditions, making it suitable for driving ADC inputs, active filters, and transducer signal chains without stability compromises.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables full functionality across depleted Li-ion (3.0 V) and regulated 3.3 V/5 V rails. |
| Gain-Bandwidth Product | 1 MHz - supports stable closed-loop gain up to 10× at 100 kHz for sensor amplification and anti-aliasing filtering. |
| Slew Rate | 1 V/µs - ensures faithful reproduction of ≤159 kHz full-scale sine waves without distortion. |
| Input Offset Voltage | 1.7 mV (max) - limits DC error to <±0.17% of full-scale in 1 V output ranges. |
| Rail-to-Rail Output Swing | V+−10 mV / V−+65 mV @ 10 kΩ - maximizes dynamic range in low-voltage systems (e.g., 3.3 V ADC reference). |
| Input Common-Mode Range | −0.2 V to V+−0.8 V - allows direct sensing of signals referenced to ground in single-supply topologies. |
| Quiescent Current | 210 µA per amplifier - extends battery life in always-on monitoring nodes (e.g., >1 year on CR2032). |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm lead pitch, thin-profile surface-mount construction optimized for space-constrained automotive modules and portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN A− | Inverting input of amplifier A - connects to feedback network in inverting configurations. |
| 2 | V− | Negative supply terminal - tied to GND in single-supply operation; must be decoupled locally. |
| 3 | IN A+ | Noninverting input of amplifier A - accepts ground-referenced sensor signals without level-shifting. |
| 4 | OUT A | Output of amplifier A - drives loads up to 10 kΩ while maintaining rail-to-rail swing. |
| 5 | OUT B | Output of amplifier B - independent channel for dual-path signal processing (e.g., differential pair). |
| 6 | IN B− | Inverting input of amplifier B - used for feedback in second-stage gain or filtering. |
| 7 | IN B+ | Noninverting input of amplifier B - supports independent biasing or reference injection. |
| 8 | V+ | Positive supply terminal - accepts 2.7–5.5 V; requires 100 nF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| No Crossover Distortion | Eliminates dead-zone nonlinearity in unity-gain buffers - critical for accurate DC-coupled signal replication. |
| AEC-Q100 Grade 3 Qualified | Validated for automotive applications operating from −40°C to +85°C with robust ESD (±900 V HBM). |
| Rail-to-Rail Output | Delivers usable output swing within 10 mV of V+ and 65 mV of V− - preserves SNR in low-voltage data acquisition. |
| Ground-Sensing Input | Input common-mode range extends 0.2 V below V− - enables direct interface with 0 V–reference sensors (e.g., thermistors). |
| Low Power Consumption | 210 µA per amplifier at 5 V - reduces thermal load and enables high-density integration in multi-channel modules. |
Applications
| Automotive Cabin Sensors | Industrial Temperature Monitoring |

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 |
|---|---|---|---|
| LMV358QDR | Same silicon, SOIC-8 package (4.90 mm × 3.91 mm); higher RθJA (207.9°C/W vs 235°C/W). | Preferred where board-level reflow compatibility with legacy SOIC footprints is required. | Select LMV358QDR when SOIC-8 mechanical fit or thermal mass for soldering is prioritized over size. |
| TSV912IDT | Higher GBWP (8 MHz), lower VOS (1.5 mV typ), but higher IQ (820 µA) and no AEC-Q100 qualification. | Suitable for high-speed, precision non-automotive applications where power budget allows. | Choose TSV912IDT only for non-automotive designs needing faster settling or tighter DC accuracy - not for Grade 3 environments. |
Compared with LMV358Q3MMX/NOPB, LMV358QDR offers identical electrical performance in a larger SOIC package ideal for manual assembly or thermal testing, while TSV912IDT trades automotive qualification and ultra-low power for higher speed and precision - requiring careful evaluation of system-level reliability and energy constraints.

FAQ
What is the operating temperature range for LMV358Q3MMX/NOPB?
The LMV358Q3MMX/NOPB is qualified to AEC-Q100 Grade 3, with a specified operating junction temperature range of −40°C to +85°C. This rating is validated per automotive stress test standards and applies across the full 2.7 V to 5.5 V supply range. The device is not rated for Grade 1 (−40°C to +125°C) operation.
Does LMV358Q3MMX/NOPB support true rail-to-rail input?
No, LMV358Q3MMX/NOPB does not feature rail-to-rail input. Its input common-mode voltage range is specified as −0.2 V to V+−0.8 V, which includes ground (V−) but does not extend to the positive rail. However, it does provide rail-to-rail output swing: V+−10 mV and V−+65 mV at 10 kΩ load.
What package type is used for LMV358Q3MMX/NOPB?
LMV358Q3MMX/NOPB is supplied in the VSSOP-8 (DGK) package: a 3.00 mm × 3.00 mm body size, 0.65 mm lead pitch, thin-profile surface-mount package. This differs from the SOIC-8 (D) variant and is optimized for high-density PCB layouts in automotive modules and portable electronics.
Is LMV358Q3MMX/NOPB pin-compatible with standard LM358 variants?
No, LMV358Q3MMX/NOPB is not pin-compatible with legacy LM358 variants. While both are dual op-amps in 8-pin packages, LMV358Q3MMX/NOPB uses the VSSOP-8 (DGK) footprint, whereas standard LM358 uses SOIC-8 (D) or PDIP-8. Pin functions differ between families - e.g., VSSOP-8 assigns pin 2 to V− and pin 8 to V+, unlike SOIC-8 pinouts.
What is the maximum capacitive load LMV358Q3MMX/NOPB can drive without external compensation?
LMV358Q3MMX/NOPB is unity-gain stable and can directly drive up to 200 pF capacitive load without oscillation or excessive peaking. This is verified per typical characteristics in the datasheet (Figure 7-23). For loads exceeding 200 pF, a series isolation resistor (e.g., 620 Ω) between output and capacitor is recommended to maintain phase margin.
