Product details
Overview
LMV358Q3MA/NOPB from Texas Instruments is a dual, general-purpose, rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 5.5 V) single-supply operation. It delivers 1 MHz gain-bandwidth product, 1 V/µs slew rate, 210 µA supply current per amplifier, −0.2 V to 4.0 V input common-mode range (including ground), and rail-to-rail output swing (V− + 65 mV to V+ − 10 mV at 10 kΩ load) - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the LMV358Q3MA/NOPB datasheet, LMV358Q3MA/NOPB pinout, LMV358Q3MA/NOPB application, or LMV358Q3MA/NOPB equivalent, this page provides verified electrical specifications, automotive-grade thermal and ESD performance (AEC-Q100 Grade 3), SOIC-8 package mapping, real-world use cases, and validated alternative options - all confirmed against TI's SNOS012K revision K datasheet and official orderable information.
Technical Context
The LMV358Q3MA/NOPB implements a bipolar-input, rail-to-rail output architecture built on TI's submicron BiCMOS process, delivering improved noise performance and higher output drive versus CMOS-input op-amps at comparable power. Its input stage supports common-mode voltage down to −0.2 V (enabling ground-referenced sensing), while its output stage achieves full swing within 10 mV of V+ and 65 mV of V− under 10 kΩ load.
It operates across −40°C to +85°C (Grade 3 automotive temperature range), with guaranteed 2.7-V and 5-V DC/AC performance, no crossover distortion, and stable unity-gain operation into 200 pF capacitive loads - making it suitable for active filters, transimpedance amplifiers, and low-side current sensing where linearity and dynamic range are critical at low supply voltages.
Key Specifications

|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports full operation across entire Li-ion battery discharge curve (3.0 V–4.2 V) without rail adjustment. |
| Gain-Bandwidth Product | 1 MHz - enables stable closed-loop gain up to 10× at 100 kHz for anti-aliasing or sensor signal amplification. |
| Slew Rate | 1 V/µs - ensures ≤1 µs settling for 1-V step inputs, sufficient for audio preamp and medium-speed data acquisition. |
| Input Offset Voltage | 1.7 mV (max) - limits DC error to <±2 mV in unity-gain buffer configurations used in precision analog front-ends. |
| Supply Current per Amplifier | 210 µA (typ) - allows dual-channel operation at <450 µA total, extending battery life in always-on wearable sensors. |
| Input Common-Mode Range | −0.2 V to V+ − 0.8 V - permits direct interface to 0 V-referenced transducers (e.g., thermistors, bridge sensors) without level-shifting. |
| Rail-to-Rail Output Swing | V− + 65 mV / V+ − 10 mV @ 10 kΩ - maximizes usable output dynamic range (>98% of supply) in 3.3-V systems. |

| 2 | IN A+ | Noninverting input for amplifier channel A - accepts grounded or biased input signals; supports common-mode down to −0.2 V. |
| 3 | OUT A | Output of amplifier channel A - drives loads up to 10 kΩ with rail-to-rail swing; requires local decoupling if driving capacitive loads >200 pF. |
| 4 | V− | Negative supply terminal - tied to system ground in single-supply operation; must be stable and low-impedance to minimize PSRR degradation. |
| 5 | V+ | Positive supply terminal - accepts 2.7–5.5 V; bypass with 100 nF ceramic capacitor near pin to suppress high-frequency noise. |
| 6 | IN B+ | Noninverting input for amplifier channel B - electrically isolated from channel A; enables independent dual-signal processing. |
| 7 | IN B− | Inverting input for amplifier channel B - used for second feedback path; matches IN A− in electrical characteristics and layout sensitivity. |

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 |
|---|---|---|---|
| LMV358DR | Same silicon, SOIC-8 package, but commercial-grade (−40°C to +125°C) without AEC-Q100 qualification; 210 µA supply current, identical AC/DC specs. | Lacks automotive qualification and Grade 3 thermal validation - suitable for industrial or consumer designs not requiring automotive reliability testing. | Select LMV358DR for cost-sensitive non-automotive applications where full AEC-Q100 compliance is unnecessary. |
| MCP6022-E/SN | CMOS-input architecture (1 pA IB vs 15 nA), lower input voltage noise (19 nV/√Hz), but only 1 MHz GBW and 0.6 V/µs slew rate; 170 µA supply current. | Better for high-impedance sensor interfaces (e.g., pH electrodes), but slower settling and reduced drive capability limit use in active filters or current sensing. | Choose MCP6022-E/SN when ultra-low input bias current is mandatory and bandwidth/slew rate requirements are relaxed. |
Compared with LMV358Q3MA/NOPB, LMV358DR offers identical performance at lower cost but lacks automotive qualification, while MCP6022-E/SN trades speed and output drive for femtoampere input bias - making LMV358Q3MA/NOPB optimal for robust, medium-speed, rail-to-rail dual-amplifier roles in harsh environments.

FAQ
What is the operating temperature range for LMV358Q3MA/NOPB?
The LMV358Q3MA/NOPB is qualified to AEC-Q100 Grade 3 standards, specifying guaranteed operation from −40°C to +85°C. This range covers under-dash automotive environments and most industrial edge-sensing applications. Unlike the commercial LMV358-N (−40°C to +125°C), the Q3 variant prioritizes reliability validation at elevated ambient temperatures typical of enclosed vehicle cabins.
Does LMV358Q3MA/NOPB support true rail-to-rail input?
No, LMV358Q3MA/NOPB features rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range extends from −0.2 V to V+ − 0.8 V, meaning it accepts signals down to 200 mV below ground (enabling ground-referenced sensing) but cannot handle inputs at the positive rail. For true rail-to-rail input, consider TI's TLV9002 or MCP6002 alternatives.
Can LMV358Q3MA/NOPB drive capacitive loads directly?
Yes - LMV358Q3MA/NOPB is specified to remain stable in unity-gain configuration driving up to 200 pF capacitive load without external compensation. This capability simplifies DAC output buffering and ADC driver designs. For loads exceeding 200 pF, TI recommends adding a series isolation resistor (e.g., 620 Ω) between the op-amp output and the capacitor to restore phase margin.
What is the maximum output current capability of LMV358Q3MA/NOPB?
LMV358Q3MA/NOPB can source up to 40 mA and sink up to 160 mA (at V+ = 5 V, TA = 25°C), though sustained operation above ±20 mA requires careful thermal management due to SOIC-8 package limitations. For continuous 10-mA loads, junction temperature rise remains within safe limits when board copper area meets TI's recommended layout guidelines.
How does LMV358Q3MA/NOPB differ from standard LMV358-N?
LMV358Q3MA/NOPB is the automotive-qualified version of LMV358-N, featuring AEC-Q100 Grade 3 certification, enhanced ESD robustness (±2000 V HBM), and rigorous lot-to-lot process controls for automotive production. Electrically, both share identical DC/AC specifications, pinout, and SOIC-8 packaging - but LMV358Q3MA/NOPB undergoes additional stress testing and traceability documentation required for Tier-1 automotive supply chains.
