Product details
Overview
LMV358Q1MAX/NOPB from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier designed for low-voltage (2.7 V to 5.5 V), single-supply applications in automotive and industrial systems. 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+ −10 mV / V− +65 mV at 10 kΩ) - enabling precision signal conditioning in battery-powered ADAS sensors and engine control modules.
For engineers reviewing the LMV358Q1MAX/NOPB datasheet, LMV358Q1MAX/NOPB pinout, LMV358Q1MAX/NOPB application, or LMV358Q1MAX/NOPB equivalent, this page provides verified technical context, AEC-Q100 Grade 1 qualification status, SOIC-8 package mapping, real-world design meaning of key specs, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The LMV358Q1MAX/NOPB implements a bipolar-input, rail-to-rail output op-amp architecture optimized for low-voltage operation. Its input stage supports common-mode voltage down to −0.2 V (enabling ground-referenced sensing), while its output stage achieves V+ −10 mV high-side and V− +65 mV low-side swing into 10 kΩ loads - critical for maximizing dynamic range in 3.3 V or 5 V systems.
It operates across −40°C to +125°C with guaranteed performance at both 2.7 V and 5 V supply rails, features no crossover distortion, and maintains 60° phase margin with 200 pF capacitive load - confirming stable unity-gain follower operation without external compensation in typical sensor interface circuits.
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 nominal 3.3 V/5 V rails without brownout. |
| Gain-Bandwidth Product | 1 MHz - enables stable closed-loop gain up to ~100× at 10 kHz for anti-aliasing or sensor amplification. |
| Slew Rate | 1 V/µs - sufficient for <1 µs settling to 0.1% on 1 V step inputs, suitable for medium-speed data acquisition. |
| Input Offset Voltage | 1.7 mV (max) - introduces ≤0.17% error in unity-gain buffer with 1 V input; no trimming required for cost-sensitive designs. |
| Supply Current (per amp) | 210 µA (typ) - draws only 420 µA total for dual-channel operation, extending battery life in always-on modules. |
| Rail-to-Rail Output Swing | V+ −10 mV / V− +65 mV @ 10 kΩ - delivers >99% of full-scale output range in 3.3 V systems, minimizing headroom loss. |
| Input Common-Mode Range | −0.2 V to V+ − 0.8 V - allows direct DC coupling of 0 V-referenced transducer signals without level-shifting. |
Pinout & Package
LMV358Q1MAX/NOPB is housed in an 8-pin SOIC package (body size 4.90 mm × 3.91 mm), optimized for automated assembly and thermal reliability in automotive PCBs. The package meets JEDEC MS-012 standards and supports infrared reflow profiles.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream ADC input or active filter stage; rail-to-rail swing ensures full utilization of 12-bit+ converter range. |
| 2 | IN– A | Inverting input for channel A - used in transimpedance or differential configurations; matched bias current minimizes offset error with feedback resistor. |
| 3 | IN+ A | Non-inverting input for channel A - accepts ground-referenced sensor outputs (e.g., thermistor divider) without level shift. |
| 4 | V− | Negative supply terminal - connected to system GND in single-supply operation; must be low-impedance to suppress noise coupling. |
| 5 | IN+ B | Non-inverting input for channel B - enables dual-sensor monitoring (e.g., dual temperature channels) with shared supply and layout efficiency. |
| 6 | IN– B | Inverting input for channel B - supports independent gain setting per channel; pin-compatible with LM358 layouts for drop-in replacement. |
| 7 | OUT B | Amplifier B output - isolates second signal path from channel A; prevents crosstalk in mixed-signal routing. |
| 8 | V+ | Positive supply terminal - accepts 3.3 V or 5 V regulated rail; decoupling capacitor (100 nF) required within 5 mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C operation in automotive powertrain and chassis systems, with full traceability and failure analysis reporting. |

| Rail-to-rail output with ground-sensing input | Enables true single-supply operation from 0 V to V+, removing need for biasing networks in low-voltage sensor front-ends. |
| 200 pF capacitive load tolerance | Stable unity-gain operation into typical ADC input capacitance or long PCB traces without external isolation resistors. |
| Low 210 µA supply current per amplifier | Reduces thermal load in sealed ECUs and extends runtime in battery-backed diagnostic modules beyond 10 years. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358DR | Commercial-grade (non-AEC-Q100); identical electrical specs but rated only to 125°C (not qualified for automotive use). | Approved for industrial automation and consumer electronics; not permitted in ASIL-B or higher automotive subsystems. | Select LMV358DR only for non-automotive designs where AEC-Q100 compliance is unnecessary and cost is primary driver. |
| MCP6022-E/SN | Higher 10 MHz GBW, lower 25 µV VOS, but 1 mA supply current - 4.8× higher quiescent power than LMV358Q1MAX/NOPB. | Suitable for high-precision, high-speed applications (e.g., active filters above 100 kHz); unsuitable for ultra-low-power battery systems. | Choose MCP6022-E/SN when bandwidth or offset accuracy outweighs power constraints; avoid when >500 µA total supply budget applies. |
Compared with LMV358Q1MAX/NOPB, LMV358DR lacks automotive qualification documentation and stress-test validation, while MCP6022-E/SN trades 4.8× higher supply current for 10× greater bandwidth and 68× lower offset - making LMV358Q1MAX/NOPB optimal for cost-sensitive, thermally constrained automotive signal chains requiring AEC-Q100 assurance.

FAQ
What is the AEC-Q100 qualification status of LMV358Q1MAX/NOPB?
LMV358Q1MAX/NOPB is AEC-Q100 Grade 1 qualified, certified for operation from −40°C to +125°C with full stress testing including HTOL, TC, UHAST, and ESD per JESD22 standards. This qualification is documented in TI's official AEC-Q100 report for the LMV358-N-Q1 family and applies directly to LMV358Q1MAX/NOPB as a SOIC-8 variant.
Does LMV358Q1MAX/NOPB support true single-supply operation with input signals at ground potential?
Yes. LMV358Q1MAX/NOPB features an input common-mode voltage range extending to −0.2 V (below ground) and up to V+ − 0.8 V, enabling direct connection of 0 V-referenced sources like thermistor dividers or bridge sensors without level-shifting circuitry - a key advantage over legacy LM358 in low-voltage designs.
What is the maximum capacitive load LMV358Q1MAX/NOPB can drive without oscillation?
LMV358Q1MAX/NOPB is specified to remain stable driving up to 200 pF in unity-gain follower configuration, as verified in TI's SNOS012K datasheet Figure 7-23 (Gain and Phase vs Capacitive Load). For loads exceeding 200 pF, TI recommends adding a 10–100 Ω isolation resistor between output and capacitance.
How does the supply current of LMV358Q1MAX/NOPB compare to standard LM358 in automotive applications?
LMV358Q1MAX/NOPB draws 210 µA per amplifier (420 µA total), versus ~1.5 mA per amplifier for LM358 - a 72% reduction. This enables longer battery backup in always-on modules and reduces thermal load in sealed ECUs, directly supporting modern automotive low-power architecture requirements.
Is LMV358Q1MAX/NOPB pin-compatible with industry-standard LM358 SOIC-8 footprints?
Yes. LMV358Q1MAX/NOPB uses the same SOIC-8 (D) package as LM358, with identical pinout: Pin 1 = OUT A, Pin 2 = IN– A, Pin 3 = IN+ A, Pin 4 = V−, Pin 5 = IN+ B, Pin 6 = IN– B, Pin 7 = OUT B, Pin 8 = V+. This allows direct drop-in replacement in existing LM358 layouts without PCB revision.
