Product details
Overview
LMV358Q3MAX/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, and rail-to-rail output swing (V+ −10 mV / V− +65 mV at 10 kΩ), with supply current of 210 µA per amplifier - enabling precision signal conditioning in battery-powered portable instrumentation and sensor interfaces.
For engineers reviewing the LMV358Q3MAX/NOPB datasheet, LMV358Q3MAX/NOPB pinout, LMV358Q3MAX/NOPB application, or LMV358Q3MAX/NOPB equivalent, key selection criteria include its AEC-Q100 Grade 3 qualification (−40°C to +85°C), input common-mode range extending to −0.2 V, no crossover distortion, and compatibility with space-constrained SOIC-8 layouts.
Technical Context
The LMV358Q3MAX/NOPB uses a bipolar input stage and rail-to-rail output stage fabricated on Texas Instruments' submicron BiCMOS process, delivering improved noise performance and higher output drive versus CMOS-input alternatives. Its input common-mode voltage range includes ground (−0.2 V to V+ − 0.8 V), supporting direct sensing near 0 V in single-supply configurations.
This device eliminates crossover distortion through internal biasing architecture, ensuring clean zero-crossing behavior in unity-gain buffers and active filters. It maintains stable operation driving up to 200 pF capacitive loads without external compensation, with phase margin ≥60° and gain margin ≥10 dB at 5 V supply.
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. |
| Gain-Bandwidth Product | 1 MHz - enables stable unity-gain buffer and 2nd-order active filter designs up to ~100 kHz. |
| Slew Rate | 1 V/µs - sufficient for 100 kHz sine wave output at 16 Vpp without distortion. |
| Input Offset Voltage | 1.7 mV (max) - ensures ≤17 mV error in 10× gain stages with 10 kΩ feedback. |
| Rail-to-Rail Output Swing | V+ −10 mV / V− +65 mV @ 10 kΩ - maximizes dynamic range in 3.3 V systems (2.99 V usable swing). |
| Input Common-Mode Range | −0.2 V to V+ − 0.8 V - allows direct interfacing to ground-referenced sensors and DAC outputs. |
| Quiescent Current | 210 µA per amplifier - enables dual-channel amplification in <1 mA total system budget. |
Pinout & Package
LMV358Q3MAX/NOPB is housed in an 8-pin SOIC package (4.90 mm × 3.91 mm body size), optimized for automated assembly and thermal performance (RθJA = 207.9°C/W).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 40 mA sourcing/sinking; rail-to-rail swing critical for ADC driver applications. |
| 2 | IN– A | Inverting input for channel A - matched impedance routing required to minimize offset drift from input bias current (15 nA typ). |
| 3 | IN+ A | Non-inverting input for channel A - accepts signals down to −0.2 V, enabling true ground-referenced sensing. |
| 4 | V− | Negative supply terminal - must be connected to system ground in single-supply operation; not floating. |
| 5 | IN+ B | Non-inverting input for channel B - electrically isolated from channel A; supports dual independent signal paths. |
| 6 | IN– B | Inverting input for channel B - requires symmetrical PCB layout vs IN+ B to reject common-mode noise. |
| 7 | OUT B | Amplifier B output - identical AC/DC specs to OUT A; enables dual-channel filtering or differential drive. |
| 8 | V+ | Positive supply terminal - decoupling capacitor (100 nF ceramic) required within 5 mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| No crossover distortion | Eliminates zero-crossing glitches in audio buffers and precision comparators, verified in voltage-follower test waveforms. |
| AEC-Q100 Grade 3 qualification | Validated for automotive infotainment and body electronics operating from −40°C to +85°C ambient. |
| Rail-to-rail output with ground-sensing input | Enables single-supply operation with full input/output dynamic range - e.g., 0–3.3 V sensor signal amplification. |
| 200 pF capacitive load drive capability | Stable unity-gain operation into typical ADC input capacitance without added isolation resistor. |
| Bipolar input stage | Delivers 15 nA typical input bias current and 46 nV/√Hz input voltage noise at 1 kHz - superior to CMOS op-amps in low-Z source apps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358QDR | Same silicon, SOIC-8 package, but AEC-Q100 Grade 1 (−40°C to +125°C) and Pb-free matte tin finish. | Required for under-hood automotive applications requiring extended temperature operation. | Select LMV358QDR when junction temperature may exceed 85°C or RoHS exemption is not needed. |
| MCP6022-E/SN | CMOS input (1 pA bias current), lower VOS (250 µV max), but only 1 MHz GBWP and no AEC-Q100 qualification. | Suitable for high-impedance sensor interfaces where bias current dominates error, but not for automotive use. | Choose MCP6022-E/SN only for non-automotive, high-Z source applications needing ultra-low input current. |
Compared with LMV358Q3MAX/NOPB, LMV358QDR offers wider temperature coverage at identical cost and footprint, while MCP6022-E/SN trades automotive qualification and bipolar noise performance for femtoampere input bias - making LMV358Q3MAX/NOPB optimal for cost-sensitive, Grade 3 automotive signal chains.

FAQ
What is the operating temperature range for LMV358Q3MAX/NOPB?
The LMV358Q3MAX/NOPB is qualified to AEC-Q100 Grade 3, specifying reliable operation from −40°C to +85°C ambient temperature. This range covers most cabin-mounted automotive electronics and industrial portable equipment, though it does not extend to under-hood environments requiring Grade 1 (−40°C to +125°C). Full electrical characteristics are ensured across this range per TI's SNOS012K datasheet.
Does LMV358Q3MAX/NOPB support true single-supply operation with input signals at ground?
Yes. The LMV358Q3MAX/NOPB features an input common-mode voltage range that includes ground (−0.2 V to V+ − 0.8 V), allowing direct connection of ground-referenced sensors or DAC outputs without level-shifting circuitry. This capability is confirmed in Section 7.4 (Recommended Operating Conditions) and Figure 7-14 (CMRR vs Input Common-Mode Voltage) of the official datasheet.
Can LMV358Q3MAX/NOPB drive a 1000-pF capacitive load stably?
No - LMV358Q3MAX/NOPB is characterized for stable unity-gain operation up to 200 pF capacitive load (Section 8.3.1). Driving 1000 pF directly risks oscillation due to phase margin degradation. For heavier loads, TI recommends using resistive isolation (e.g., 620 Ω in series with output) or the feed-forward compensation network shown in Figure 8-5 of the datasheet to restore stability without sacrificing DC accuracy.
What is the maximum output current capability of LMV358Q3MAX/NOPB?
The LMV358Q3MAX/NOPB provides ±40 mA continuous output current (sourcing and sinking) per amplifier, as specified in Section 7.9 (5-V DC Electrical Characteristics) under "Output Short Circuit Current". At room temperature and 5 V supply, typical sourcing current reaches 40 mA before limiting, and sinking current exceeds 10 mA - sufficient for driving LEDs, small relays, or ADC input capacitance with margin.
Is LMV358Q3MAX/NOPB pin-compatible with standard LM358 variants?
Yes - LMV358Q3MAX/NOPB uses the industry-standard SOIC-8 pinout (pin 1 = OUT A, pin 2 = IN– A, etc.), matching LM358, LM358DR, and LMV358-N variants. However, note that LMV358Q3MAX/NOPB operates down to 2.7 V and features rail-to-rail output, whereas LM358 requires ≥3 V and has limited output swing - so direct substitution is electrically safe but may require verification of supply voltage and load interface conditions.
