LMV358SG-13 Visão geral
A rail-to-rail output operational amplifier is a type of operational amplifier (OP-Amp) whose output voltage can approach both supply rails, unlike traditional amplifier topologies whose swing is limited to 1.5-2 V below each rail. Within the broader hierarchy, this device belongs to the linear amplifier family, which sits under integrated circuits and power management/analog signal chain categories. Rail-to-rail capability enables designs to maximize dynamic range in low-voltage single-supply systems such as battery-powered portable equipment.
Key features include a 1 MHz gain-bandwidth product, 1 V/µs slew rate, low-voltage 2.7 V to 5.5 V single-supply operation, and CMOS input architecture suitable for general-purpose signal conditioning. The LMV321/LMV358/LMV324 family from which this part derives was designed to effectively reduce cost and footprint at low voltage levels, with the SG-13 suffix indicating 8-SOIC package and 13-inch reel quantity. This makes the part especially attractive for high-volume consumer and industrial designs.
Internally the device uses CMOS input stages that support low input bias current and a common-mode range that includes the negative rail, while the output stage is designed to swing within millivolts of either rail. Compared with bipolar-input rail-to-rail op amps, the LMV358 family typically delivers lower input bias current at the cost of slightly higher input-referred voltage noise.
Typical applications include portable consumer electronics, battery-powered sensor interfaces, signal conditioning for ADC front-ends, general-purpose active filters, headphone driver stages, and transducer pre-amplification. The dual-channel configuration allows space-efficient implementation of difference amplifiers, instrumentation front-ends, or dual-pole Sallen-Key filters.
When designing with this part, ensure input common-mode voltage stays within the specified range, place a 0.1 µF decoupling capacitor close to the supply pin, and verify output drive capability against the load. The rail-to-rail output stage requires minimum output current loading to maintain linearity near the rails.

Aplicações típicas
LMV358SG-13 é adequado para 6 aplicaçãos: Battery-Powered Sensor Signal Conditioning, Active Audio Signal Filtering, ADC Front-End Buffer and Driver, Portable Consumer Electronics, Industrial Control Loop Driver, General-Purpose Comparator and Threshold Detector.
Battery-Powered Sensor Signal Conditioning
The LMV358SG-13 fits battery-powered sensor signal conditioning because it operates from a single 2.7 V to 5.5 V supply and provides rail-to-rail output swing, maximizing dynamic range on low-voltage rails. With 1 MHz GBW and 1 V/µs slew rate, it handles transducer outputs from thermistors, photodiodes, and strain gauges without saturation. The dual channel allows simultaneous conditioning of two sensors or implementation of a difference amplifier with the second channel. Compared to the legacy LM358, the LMV358SG-13 consumes less quiescent current and supports true 3.3 V single-supply operation typical of Li-ion battery-powered IoT nodes.
Recomendado
Active Audio Signal Filtering
For low-frequency audio active filter designs the LMV358SG-13 provides 1 MHz of gain-bandwidth product that comfortably supports Sallen-Key and multiple-feedback topologies up to tens of kHz. Rail-to-rail output prevents clipping when filter output approaches supply rails at high input amplitudes, improving THD performance. The dual channel enables stereo two-pole filtering or single-channel four-pole cascades without a second IC. Estimated quiescent current around 0.5 mA per channel keeps thermal load low for portable headphone and line-driver stages.
Recomendado
ADC Front-End Buffer and Driver
The LMV358SG-13 suits ADC front-end buffering because its rail-to-rail output allows full-scale drive of single-supply ADCs operating from 3.3 V or 5 V without loss of codes near the rails. The 1 MHz GBW is sufficient to settle 12-bit SAR converters at sample rates up to approximately 100 kSPS. Low input bias current from the CMOS input stage is compatible with high-impedance sensor sources. The dual configuration supports simultaneous buffering of two ADC channels or a buffered input plus reference buffer with one chip.
Recomendado
Portable Consumer Electronics
The LMV358SG-13 fits portable consumer designs including handheld toys, remote controls, and personal care products where the part must operate from 2 AA cells or a single Li-ion cell. Its 2.7 V minimum supply voltage enables operation down to battery end-of-life, extending usable runtime. Rail-to-rail output preserves dynamic range at low battery voltages where the legacy LM358 would clip. Low cost at volume pricing around $0.13 per unit at 2500-piece reel makes it attractive for cost-sensitive consumer SKUs.
Recomendado
Industrial Control Loop Driver
For industrial 4-20 mA current loop receivers and 0-10 V signal conditioning, the LMV358SG-13 provides dual rail-to-rail channels that interface to 5 V industrial supply rails. The wide operating temperature range of -40 °C to +85 °C supports factory-floor and outdoor enclosure environments. The 1 MHz GBW handles industrial control bandwidths up to tens of kHz with substantial margin. Two channels in one 8-SOIC package reduce PCB area and bill-of-materials count for transmitter and receiver circuits.
Recomendado
General-Purpose Comparator and Threshold Detector
The LMV358SG-13 functions as a low-cost threshold detector and comparator when used in open-loop configuration, with rail-to-rail input common-mode range when input signals approach supply rails. The 1 V/µs slew rate delivers millisecond response times suitable for battery voltage monitoring, charge-termination detection, and alarm threshold circuits. Dual channels support window comparator topologies monitoring both over- and under-voltage conditions. Operating from 2.7 V enables single-cell Li-ion direct monitoring without a separate reference.

Notas de projeto
Place a 0.1 µF X7R ceramic decoupling capacitor within 5 mm of the V+ pin (pin 8) to the V- pin (pin 4). For mixed-signal boards sharing a digital supply, add a ferrite bead and 10 µF bulk capacitor to isolate analog and digital rails. The LMV358SG-13 draws modest quiescent current (typically ~0.5 mA per channel), so total supply current for both channels stays around 1 mA, allowing small bypass capacitors to be used without high inrush handling. Estimated: based on typical CMOS op-amp IDD values; consult datasheet for min/max bounds at temperature extremes.
Route input traces away from noisy digital or switching traces. Keep feedback network traces short to minimize parasitic capacitance that can degrade phase margin at high closed-loop gains. The 8-SOIC package has standard 1.27 mm pin pitch, so standard SOIC-8 land patterns apply. For high-impedance CMOS inputs, guard rings around the input traces reduce leakage and noise pickup, especially in high-temperature or contaminated PCB environments.
Do not exceed the absolute maximum supply voltage of 6.5 V or apply input voltages beyond the supply rails. The CMOS input stage has limited ESD protection compared to bipolar-input op amps, so add external ESD diodes for hot-plug or human-touch interfaces. Avoid driving large capacitive loads (>1 nF) directly without a series isolation resistor, which can cause instability due to the output stage's limited phase margin. The rail-to-rail output stage needs minimum load current (~1 kΩ to either rail) to maintain specified linearity near the rails.
The 8-SOIC package has thermal resistance theta_JA around 150 °C/W, giving a thermal margin of approximately 0.7 W at 85 °C ambient. Power dissipation in this op amp is dominated by quiescent current times supply voltage, plus load current times rail-to-rail swing. Estimated: 1 mA total IDD × 5 V = ~250 mW quiescent, leaving headroom for ~400 mW of load dissipation at 85 °C ambient. No heatsink required for typical sensor-conditioning loads.
