Product details

Overview

LMV358SG-13 from Diodes Incorporated is a dual, rail-to-rail output operational amplifier optimized for low-voltage (2.7V–5.5V) general-purpose applications. It delivers 1 MHz gain-bandwidth, 1 V/µs slew rate, 190 µA typical supply current per amplifier, and operates across –40°C to +125°C. It serves as a cost-effective signal conditioning and buffering IC in portable sensor interfaces and battery-powered analog front-ends.

For engineers reviewing the LMV358SG-13 datasheet, LMV358SG-13 pinout, LMV358SG-13 application, or LMV358SG-13 equivalent, key selection criteria include rail-to-rail output swing (V₊ – 10 mV / V_– + 10 mV at 10 kΩ), input common-mode range extending to ground (–0.2 V to V₊ – 0.8 V), and guaranteed 2.7V/5V operation with low quiescent current.

Technical Context

The LMV358SG-13 integrates two independent CMOS op-amps in a single SO-8 package, each featuring rail-to-rail output stage architecture enabling full dynamic range utilization near supply rails. Its input stage supports common-mode voltage down to –0.2 V, allowing direct interfacing with grounded sensors and single-supply ADC drivers.

It employs a unity-gain stable internal compensation scheme delivering 1 MHz GBWP and 60° phase margin with 200 pF capacitive load. The device eliminates crossover distortion and achieves 50–65 dB CMRR over 0 V to 4.0 V input common-mode range, supporting precision DC-coupled amplification in noisy environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	2.7 V to 5.5 V - Enables direct use with Li-ion, 3.3 V, and 5 V logic rails without level-shifting.
Gain-Bandwidth Product	1 MHz - Supports stable closed-loop gain up to 10× at 100 kHz for anti-aliasing and active filtering.
Slew Rate	1 V/µs - Limits large-signal settling time to ≤1 µs for 1 V step, suitable for moderate-speed signal conditioning.
Input Offset Voltage	1.7–7 mV (typ) - Defines DC error budget in precision gain stages; drift of 5 µV/°C impacts thermal stability.
Rail-to-Rail Output Swing	V₊ – 10 mV / V_– + 10 mV @ 10 kΩ - Maximizes usable output voltage range in single-supply systems.
Input Common-Mode Range	–0.2 V to V₊ – 0.8 V - Allows input signals referenced to ground or negative bias without clipping.
Quiescent Current	190 µA typ (both amps) - Enables ultra-low-power operation in always-on sensor nodes and wearables.

Pinout & Package

LMV358SG-13 is housed in an SO-8 (Small Outline-8) surface-mount package with standard 1.27 mm pitch, JEDEC MS-012AC compliant outline, and green (halogen/antimony-free) molding compound.

Pin/Terminal	Circuit Role	Design Meaning
1	OUTA	Amplifier A output - Drives loads up to 10 kΩ while maintaining rail-to-rail swing.
2	INA–	Inverting input of Amp A - High-impedance node (10 nA bias current); requires matched trace impedance for noise rejection.
3	INA+	Non-inverting input of Amp A - Accepts signals from –0.2 V to V₊ – 0.8 V; enables ground-referenced sensor inputs.
4	V–	Negative supply (GND in single-supply config) - Shared return path for both amplifiers; must be low-impedance.
5	INB+	Non-inverting input of Amp B - Independent channel; identical electrical specs to INA+.
6	INB–	Inverting input of Amp B - Supports differential or inverting configurations without crosstalk degradation.
7	OUTB	Amplifier B output - Fully independent output stage; no shared loading effects with OUTA.
8	V+	Positive supply - Supplies both amplifiers; decoupling capacitor required within 1 cm of pin 8.

Key Features

Feature	Design Value
Rail-to-rail output swing	Delivers >99% of supply rail range at 10 kΩ load, preserving dynamic range in 3.3 V systems.
Guaranteed 2.7 V operation	Ensures functional performance down to single-cell Li-ion (2.7 V cutoff), eliminating brownout failures.
–40°C to +125°C operating range	Supports under-hood automotive, industrial control, and outdoor IoT deployments without derating.
Crossover distortion elimination	Enables clean small-signal amplification near zero-crossing points in audio and sensor AC paths.
Green RoHS-compliant packaging	SO-8 package uses halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb).

Applications

Active Filter Stage

Portable Sensor Interface

Use Scenario: Second-order Sallen-Key low-pass filter in handheld medical pulse oximeter front-end.

IC Role / Device Role / Timing Role: Dual op-amp implements unity-gain buffer + filter integrator; one section buffers photodiode current-to-voltage conversion, the other shapes frequency response.

Use Scenario: Signal conditioning for MEMS accelerometer in battery-powered predictive maintenance sensor node.

IC Role / Device Role / Timing Role: Amplifies ±200 mV differential output to 0–3.3 V single-ended range; second amplifier provides reference bias and offset trimming.

Use Value: Input common-mode range including ground allows direct connection to unbuffered MEMS outputs; 190 µA total quiescent current extends battery life beyond 2 years at 1 Hz sampling.

Low-Voltage Power Monitor

Industrial Analog Output Driver

Use Scenario: Battery voltage supervision circuit in smart lock controller using 2× AA alkaline cells (1.0–3.2 V range).

IC Role / Device Role / Timing Role: Configured as comparator with hysteresis (using Amp A) and reference generator (Amp B as voltage follower on resistive divider).

Use Value: Guaranteed 2.7 V operation ensures reliable trip-point detection down to 2.7 V; rail-to-rail output drives microcontroller GPIO directly without pull-up.

Use Scenario: 4–20 mA loop transmitter output stage in factory automation PLC module.

IC Role / Device Role / Timing Role: One amplifier acts as current-sense feedback integrator in Howland current source topology; second provides V/I conversion scaling.

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
LMV358M8G-13	Same die, MSOP-8 package (3.0 × 3.0 mm vs SO-8's 4.9 × 6.0 mm); 203 °C/W θ_JA vs 150 °C/W.	Better thermal performance in high-density layouts; smaller footprint but tighter soldering tolerance.	Select for space-constrained PCBs where thermal dissipation is managed via copper pour or airflow.
TSV912IDT	Higher GBWP (8 MHz), lower V_OS (1.5 mV max), but 550 µA supply current; same SO-8 footprint.	Superior AC performance and DC accuracy, but 2.9× higher power draw limits battery use.	Select when bandwidth or offset sensitivity outweighs quiescent current constraints, e.g., in active anti-aliasing filters.

Compared with LMV358M8G-13, LMV358SG-13 offers lower thermal resistance in larger SO-8 packages for higher ambient temperature reliability; versus TSV912IDT, it trades bandwidth and offset for 65% lower supply current-critical for multi-year battery operation.

FAQ

What is the maximum capacitive load the LMV358SG-13 can drive without instability?

The LMV358SG-13 is unity-gain stable up to 200 pF capacitive load, as verified by phase margin ≥60° in the datasheet. Driving >200 pF requires external isolation resistor (e.g., 10–100 Ω in series with output) to maintain stability, especially in cable-driven or long-trace applications.

Does LMV358SG-13 support true single-supply operation with input signals at ground potential?

Yes. Its input common-mode voltage range extends to –0.2 V (below ground) and up to V₊ – 0.8 V, enabling direct connection of ground-referenced sensors (e.g., thermistors, bridge transducers) without level-shifting circuitry or negative supply rails.

How does the 190 µA typical supply current scale across temperature and supply voltage?

Supply current remains stable across –40°C to +125°C and 2.7–5.5 V supply range: 190–340 µA (typ) at +25°C, rising to ≤600 µA over full temperature range. This predictable increase supports accurate battery-life modeling in wide-temperature deployments.

Can LMV358SG-13 replace legacy LM358 in existing designs?

Yes-with caveats. LMV358SG-13 offers rail-to-rail output and lower supply current but has different input offset voltage (1.7–7 mV vs LM358's 2–7 mV) and reduced output drive into low impedances (<2 kΩ). Verify loop stability and DC error margins before drop-in replacement.
