Product details
Overview
LMV358MMX 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 210 µA supply current per amplifier - enabling precision signal conditioning in space-constrained portable electronics. Its input common-mode range includes ground and output swings to within 10 mV of V+ and 65 mV of V− at 10 kΩ load.
For engineers reviewing the LMV358MMX datasheet, LMV358MMX pinout, LMV358MMX application, or LMV358MMX equivalent, this page provides verified electrical parameters, SOIC-8 package mapping, automotive-grade alternatives, and real-world use cases in battery-powered sensor interfaces, active filtering, and low-voltage analog front-ends - all grounded in TI's SNOS012K revision K (August 2020) production data.
Technical Context
The LMV358MMX employs a bipolar input stage and rail-to-rail output stage fabricated on TI's submicron BiCMOS process, delivering improved noise performance (39 nV/√Hz at 1 kHz) and higher output drive versus CMOS-input op-amps. It eliminates crossover distortion through internal biasing architecture, ensuring clean zero-crossing behavior in unity-gain buffers.
Designed as a drop-in low-voltage upgrade to LM358, it maintains functional compatibility while extending operation down to 2.7 V and guaranteeing performance across −40°C to +125°C. Input common-mode voltage range spans −0.2 V to V+−0.8 V, supporting direct ground-referenced sensing in single-supply configurations.

Pinout & Package
LMV358MMX is supplied in an 8-pin SOIC package (body size 4.90 mm × 3.91 mm), 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 enables full utilization of supply headroom. |

| 3 | IN+ A | Noninverting input for channel A - accepts signals from −0.2 V to V+−0.8 V, including ground-referenced sensors. |
| 4 | V− | Negative supply terminal - connects to GND in single-supply mode; must be decoupled with 0.1-µF ceramic capacitor. |
| 5 | IN+ B | Noninverting input for channel B - electrically isolated from channel A; supports independent signal paths. |
| 6 | IN− B | Inverting input for channel B - identical electrical characteristics to pin 2; enables matched dual-channel feedback networks. |

FAQ
What is the maximum operating temperature for LMV358MMX?
The LMV358MMX is rated for continuous operation from −40°C to +125°C under recommended conditions (Section 7.4 of SNOS012K). This industrial temperature range is ensured across its full 2.7–5.5 V supply range and applies to both DC and AC specifications, making it suitable for under-hood automotive accessories or factory-floor sensors where ambient heat exceeds 85°C.
Does LMV358MMX support true single-supply operation with input signals at ground?
Yes. The LMV358MMX features an input common-mode voltage range that includes V− (ground) - specified as −0.2 V to V+−0.8 V. This allows direct connection of ground-referenced sources like thermistors or current-sense resistors without external level-shifting circuitry, simplifying design and reducing component count in single-supply systems.
Can LMV358MMX drive capacitive loads directly?
The LMV358MMX is stable driving up to 200 pF in unity-gain configuration (Section 8.3.1). For heavier loads (e.g., LCD bias lines or long cables), TI recommends adding a series isolation resistor (e.g., 620 Ω) between the output and capacitive load to preserve phase margin - verified in Figure 8-3 and Figure 8-4 of the datasheet.
What is the typical input bias current of LMV358MMX at 5 V supply?
At V+ = 5 V and TA = 25°C, the LMV358MMX exhibits a typical input bias current of 15 nA (Section 7.9). This low value minimizes voltage error across high-impedance feedback networks - for example, a 100-kΩ resistor contributes only 1.5 mV offset, well within the 7-mV typical VOS specification.
Is LMV358MMX pin-compatible with LM358?
Yes - LMV358MMX uses the same SOIC-8 pinout as LM358 (pin 1 = OUT A, pin 2 = IN− A, etc.), enabling drop-in replacement in existing designs. However, LMV358MMX operates down to 2.7 V (vs. LM358's 3 V minimum) and guarantees rail-to-rail output swing, offering improved dynamic range in low-voltage systems without layout changes.
