Product details
Overview
LMV358Q1MA/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 operation in automotive and industrial signal conditioning. 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 sensing and buffering in battery-powered ADAS sensors and body control modules.
For engineers reviewing the LMV358Q1MA/NOPB datasheet, LMV358Q1MA/NOPB pinout, LMV358Q1MA/NOPB application, or LMV358Q1MA/NOPB equivalent, this AEC-Q100 Grade 1 qualified device supports design-in for automotive temperature-critical analog front-ends, low-power sensor interfaces, and cost-sensitive industrial I/O modules where rail-to-rail output swing and ground-sensing capability are required.
Technical Context
The LMV358Q1MA/NOPB implements a bipolar-input, bipolar-output stage architecture optimized for low-voltage operation, eliminating crossover distortion while maintaining compatibility with legacy LM358 functionality. Its input stage accepts common-mode voltages down to −0.2 V (enabling true ground-referenced sensing), and its output stage drives within 10 mV of V+ and 65 mV of V− under 10-kΩ load.
It operates across −40°C to +125°C with guaranteed 2.7-V and 5-V performance, features 50 dB minimum CMRR and PSRR over full common-mode range, and achieves stable unity-gain operation with up to 200 pF capacitive load 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. |
| Gain-Bandwidth Product | 1 MHz - enables stable closed-loop gain ≥10 at 100 kHz for anti-aliasing and active filtering. |
| Slew Rate | 1 V/µs - ensures ≤1 µs settling for 1-V step inputs, suitable for medium-speed sensor signal conditioning. |
| Input Offset Voltage | 1.7 mV (max) - limits DC error to <±2 mV in unity-gain buffer configurations at room temperature. |
| Supply Current (per amp) | 210 µA (typ) - allows dual-amplifier operation on <500 µA total, critical for always-on automotive subsystems. |
| 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). |
| Input Common-Mode Range | −0.2 V to V+ − 0.8 V - permits direct connection of grounded transducer outputs without level-shifting. |
Pinout & Package
LMV358Q1MA/NOPB is packaged in an 8-pin SOIC (D package), 4.90 mm × 3.91 mm body size, with standard dual-opamp pinout compatible with industry-layout conventions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load; rail-to-rail capable; requires no pull-up/pull-down for default operation. |
| 2 | IN− A | Inverting input, channel A - high-impedance node; bias current ≤250 nA (max) at 25°C. |
| 3 | IN+ A | Noninverting input, channel A - accepts signals from −0.2 V to V+ − 0.8 V; includes ground reference. |
| 4 | V− | Negative supply terminal - connects to GND in single-supply use; must be decoupled locally with 0.1 µF ceramic. |
| 5 | IN+ B | Noninverting input, channel B - electrically identical to Pin 3; enables independent second signal path. |
| 6 | IN− B | Inverting input, channel B - matched to Pin 2; supports differential or inverting configurations for second channel. |
| 7 | OUT B | Amplifier B output - fully independent of OUT A; shares same rail-to-rail drive capability and load specs. |
| 8 | V+ | Positive supply terminal - accepts 2.7–5.5 V; thermal resistance RθJA = 207.9°C/W (SOIC D). |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358QDRQ1 | Same silicon, SOIC-8 tape-and-reel packaging (no lead finish specification); identical electrical specs and AEC-Q100 Grade 1 rating. | No functional difference; differs only in packaging format and reel quantity - suitable for automated SMT lines requiring tape feed. | Select LMV358QDRQ1 when high-volume pick-and-place assembly is required; LMV358Q1MA/NOPB preferred for prototyping and low-MOQ orders. |
| MCP6022-E/SN | Higher 10 MHz GBW, 2.2 V/µs slew rate, but higher 1 mA supply current; not AEC-Q100 qualified; wider 2.7–6.0 V supply range. | Better for high-speed filtering or driving heavier capacitive loads (>1 nF); unsuitable for automotive safety-critical modules due to lack of qualification. | Choose MCP6022-E/SN only for non-automotive industrial designs needing higher bandwidth and accepting higher power; LMV358Q1MA/NOPB remains optimal for AEC-Q100-compliant systems. |
Compared with LMV358QDRQ1, LMV358Q1MA/NOPB offers identical performance in a lead-free, RoHS-compliant SOIC package with matte tin lead finish - ideal for hand-soldering and evaluation.

FAQ
What is the maximum operating temperature for LMV358Q1MA/NOPB?
The LMV358Q1MA/NOPB is rated for continuous operation from −40°C to +125°C ambient temperature and is AEC-Q100 Grade 1 qualified. All electrical specifications - including input offset voltage, CMRR, and output swing - are guaranteed across this full range, making it suitable for under-hood and powertrain applications where thermal stress is severe. The device's SOIC package has a junction-to-ambient thermal resistance of 207.9°C/W.
Does LMV358Q1MA/NOPB support true single-supply operation with input signals at ground?
Yes. LMV358Q1MA/NOPB features an input common-mode voltage range extending to −0.2 V (below ground) and up to V+ − 0.8 V, enabling direct interfacing with grounded sensors such as thermistors, RTDs, and current-sense shunts without level-shifting circuitry. This ground-sensing capability is maintained across the full −40°C to +125°C temperature range and is explicitly specified in the datasheet's DC characteristics tables.
What is the output drive capability of LMV358Q1MA/NOPB at 3.3 V supply?
At V+ = 3.3 V and V− = 0 V, LMV358Q1MA/NOPB delivers rail-to-rail output swing of V+ − 10 mV (3.29 V) and V− + 65 mV (0.065 V) into a 10-kΩ load. Short-circuit current is rated at ±40 mA (sinking) and +5 to +60 mA (sourcing), allowing direct driving of moderate-impedance loads like ADC reference buffers, LED indicators, or small MOSFET gates without external boost stages.
Is LMV358Q1MA/NOPB pin-compatible with standard LM358 packages?
No. While LMV358Q1MA/NOPB shares the same functional pinout (SOIC-8) as LM358, it is not a drop-in replacement due to differences in input stage architecture, rail-to-rail output behavior, and guaranteed low-voltage operation. LM358 requires ≥5 V supply and exhibits crossover distortion; LMV358Q1MA/NOPB operates down to 2.7 V and eliminates crossover distortion. Layout reuse is possible, but circuit validation - especially for input biasing and output loading - is required.
What packaging and lead finish does LMV358Q1MA/NOPB use?
LMV358Q1MA/NOPB is supplied in an 8-pin SOIC (D package) with matte tin (Sn) lead finish, RoHS-compliant and lead-free per JEDEC J-STD-609. The package measures 4.90 mm × 3.91 mm and is qualified for reflow soldering per J-STD-020. The "/NOPB" suffix explicitly denotes lead-free, halogen-free construction - critical for automotive and industrial compliance requirements.
