Product details
Overview
LMV358M from Texas Instruments is a dual, low-voltage (2.7 V to 5.5 V), rail-to-rail output operational amplifier optimized for space-constrained, cost-sensitive applications. It delivers 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier at 25°C - enabling precision signal conditioning in battery-powered and single-supply systems such as HVAC sensor interfaces and portable media player audio stages.
For engineers reviewing the LMV358M datasheet, LMV358M pinout, LMV358M application, or LMV358M equivalent, key selection criteria include its guaranteed operation from –40°C to +125°C, rail-to-rail output swing (e.g., within 100 mV of rails at 2.7 V with 10 kΩ load), input offset voltage ≤7 mV (typ), and SOIC-8 package compatibility with legacy LM358 footprints while supporting lower supply voltages.
Technical Context
The LMV358M implements a complementary-input-stage architecture enabling rail-to-rail output swing without crossover distortion, critical for accurate low-voltage signal reconstruction. Its input stage operates down to ground, supporting single-supply configurations where the common-mode input range must include 0 V.
Designed for 2.7 V–5.5 V operation, it maintains stable unity-gain performance (1 MHz bandwidth, 60° phase margin) across temperature and load conditions, including capacitive loads up to 1 nF - verified via TI's stability characterization with 2 kΩ and 100 kΩ resistive loads and varying CL.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 5.5 V - enables direct integration into 3.3 V and 5 V systems without level-shifting or LDO overhead |
| Unity-Gain Bandwidth | 1 MHz - supports audio-band amplification and sensor signal conditioning up to ~100 kHz closed-loop |
| Slew Rate | 1 V/μs - ensures <1% THD for 10 kHz sine waves at 2 VPP output swing under 10 kΩ load |
| Input Offset Voltage | ≤7 mV (typ) at 25°C - limits DC error in precision gain stages and active filters requiring <10 mV baseline accuracy |
| Rail-to-Rail Output | Swings within 100 mV of VCC+ and GND at 2.7 V/10 kΩ - preserves dynamic range in low-voltage ADC driver and comparator reference circuits |

| Operating Temperature | –40°C to +125°C - qualified for industrial motor control feedback loops and automotive cabin HVAC modules |
Pinout & Package
LMV358M is packaged in an 8-pin SOIC (D package), 4.90 mm × 6.00 mm body size with standard 1.27 mm pitch - compatible with automated SMT assembly and legacy LM358 PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier A output | Drives external load or next-stage input; rail-to-rail swing supports full-scale ADC interfacing |
| 2 (1IN–) | Amplifier A inverting input | Accepts feedback network or inverted signal path; high-impedance node (<250 nA bias current) |
| 3 (1IN+) | Amplifier A noninverting input | Receives reference or sensor signal; common-mode range includes GND for single-supply use |
| 4 (GND) | Negative supply terminal | System ground return; must be low-impedance to minimize noise coupling between amplifiers |
| 5 (2IN+) | Amplifier B noninverting input | Independent signal path input; identical electrical specs to Pin 3 |
| 6 (2IN–) | Amplifier B inverting input | Supports differential configuration or independent gain stage; shares same bias current spec as Pin 2 |
| 7 (2OUT) | Amplifier B output | Second independent output channel; enables dual-sensor buffering or stereo audio preamp |
| 8 (VCC+) | Positive supply terminal | Single 2.7–5.5 V rail powers both amplifiers; decoupling capacitor required near Pin 8 |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| LMV358A | Upgraded version: lower input offset voltage (1.8 mV max vs 7 mV typ), improved PSRR (65 dB min), and enhanced ESD robustness (2.5 kV HBM). | Preferred for precision sensor front-ends requiring <2 mV DC error; not necessary for general-purpose buffering. | Select LMV358A when tighter DC specs or higher reliability in handling ESD-prone environments is required. |
| MCP6022 | Higher bandwidth (10 MHz), lower input bias current (1 pA), but higher supply current (1 mA per amp) and narrower supply range (2.7–6 V). | Better suited for high-speed filtering or photodiode transimpedance; overkill for basic signal conditioning. | Choose MCP6022 only if >1 MHz closed-loop bandwidth or femtoampere-level input leakage is mandatory. |
Compared with LMV358A and MCP6022, the LMV358M offers the optimal balance of cost, low-voltage operation, and proven industrial temperature reliability - making it ideal for volume consumer and industrial applications where 1 MHz bandwidth and sub-1 mA total supply current are sufficient.

FAQ
What is the maximum operating supply voltage for LMV358M?
The absolute maximum supply voltage for LMV358M is 5.5 V. Operation beyond this risks permanent damage. The recommended operating range is 2.7 V to 5.5 V, with full electrical specifications guaranteed across this span - including rail-to-rail output swing and 1 MHz bandwidth at both 2.7 V and 5 V supplies.
Does LMV358M support true rail-to-rail input?
No, LMV358M does not feature rail-to-rail input. Its common-mode input voltage range extends to GND (0 V) but only up to VCC – 1.2 V at 25°C. However, the output swings rail-to-rail - within 100 mV of both VCC+ and GND under typical 10 kΩ load conditions - making it ideal for single-supply output stages.
Can LMV358M replace LM358 in existing designs?
Yes, LMV358M is pin-compatible with LM358 in SOIC-8 packages and offers identical pinout and footprint. It improves upon LM358 by supporting lower supply voltages (2.7 V vs 3 V minimum), delivering rail-to-rail output (vs limited swing), and operating across –40°C to +125°C - with no PCB changes required for most legacy designs.
What is the thermal resistance (RθJA) of LMV358M in SOIC-8 package?
The junction-to-ambient thermal resistance (RθJA) for LMV358M in the D (SOIC-8) package is 207.9°C/W, as specified in TI's SLOS263Y datasheet Section 6.6. This value assumes standard JEDEC 2-layer board conditions and guides thermal design for continuous operation at elevated ambient temperatures.
Is LMV358M suitable for driving capacitive loads?
LMV358M is stable with capacitive loads up to 1 nF when driving 2 kΩ or higher resistive loads, as confirmed by TI's stability characterization (Figures 6-6 through 6-9). For loads >100 pF, adding a small series resistor (e.g., 10–50 Ω) at the output is recommended to maintain phase margin above 45° and prevent peaking or oscillation.
