LM358N Visão geral
An operational amplifier is an amplifier IC that uses high open-loop gain to amplify the difference between its non-inverting and inverting inputs. In feedback configurations, the LM358N can provide voltage gain, buffering, filtering, summing, and current-control functions. It belongs to the hierarchy of operational amplifier, analog amplifier, analog IC, and semiconductor.
The verified product information identifies the LM358-N as a dual, 32 V, 1 MHz op amp. The LM358N package is listed by distributors as an 8-pin mini-DIP or 8-pin PDIP package, depending on the manufacturer source. Because the supplied data does not include every electrical limit, several detailed parameters remain marked as data-needed rather than inferred.
Each internal amplifier is designed for general-purpose signal conditioning. The device is suitable for industrial control, sensor interfaces, audio and communication circuits, power-control loops, transducers, and low-frequency analog signal chains. Its dual architecture reduces the number of IC packages required when two independent amplifier functions are needed.
The most important design consideration is supply and input/output range. The 32 V maximum device rating does not mean every circuit should operate at 32 V. Designers must verify the selected manufacturer version, common-mode range, output swing, input bias behavior, noise, slew rate, and thermal limits before finalizing a design. The verified sources do not provide a complete, unified parameter table for this page.
This page combines the verified manufacturer and distributor references, package references, and cross-reference search results with practical engineering guidance. It is intended to help engineers locate the datasheet, assess compatibility, and plan a validation review before purchasing or substituting LM358N.

Aplicações típicas
LM358N é adequado para 6 aplicaçãos: Industrial Sensor Signal Conditioning, Audio Preamplification, Power-Control Feedback Loops, Low-Frequency Active Filters, Data Acquisition Buffering, Communication Interface Circuits.
Industrial Sensor Signal Conditioning
LM358N fits many industrial sensor-conditioning stages because it contains two independent, internally frequency-compensated amplifiers in one 8-pin DIP package. One channel can amplify or buffer a sensor output while the second channel can provide gain, level shifting, or an active-filter function. The verified source identifies approximately 1 MHz nominal gain-bandwidth performance and single-supply operation as key family characteristics. Before choosing the device, verify input bias current, offset voltage, common-mode range, output swing, and noise against the sensor impedance and supply voltage. In high-impedance sensor circuits, input bias current can dominate the design even when the signal bandwidth is low.
Recomendado
Audio Preamplification
LM358N can be used for general-purpose audio preamplification and active audio signal conditioning when the design operates within the amplifier's supply and signal-range limits. Its dual architecture allows one channel to provide voltage gain and the other to buffer or perform a companion filtering function. The verified material identifies a 32 V device rating and approximately 1 MHz bandwidth, but does not provide the exact noise, slew-rate, input-voltage, or output-swing limits for the selected supplier. Check those specifications in the exact manufacturer datasheet, especially for low-noise microphone paths or designs requiring large output swing.
Recomendado
Power-Control Feedback Loops
LM358N is appropriate for many low-frequency power-control and feedback loops where two independent amplifier channels simplify current sensing, error amplification, or actuator drive. The approximately 1 MHz nominal gain-bandwidth figure provides useful context for loop-bandwidth planning, while the internally frequency-compensated architecture simplifies ordinary closed-loop amplifier use. Engineers must still verify input common-mode range, output swing, supply current, and stability behavior for the selected manufacturer variant. A feedback loop also requires checking startup, saturation recovery, noise, and the sensor or power-stage transfer function rather than relying only on the bandwidth number.
Recomendado
Low-Frequency Active Filters
LM358N can implement low-frequency active filters, integrators, and signal-shaping networks when the target frequencies are well below its approximately 1 MHz nominal gain-bandwidth performance. The two amplifiers may be used as a cascaded filter, buffer-plus-filter arrangement, or paired stage in a multi-pole network. Component tolerances, op-amp input bias current, output loading, and supply headroom strongly affect the realized response. The supplied data does not state the exact noise or input-current limits, so high-impedance filter designs should be validated against the specific manufacturer datasheet and the actual source impedance.
Recomendado
Data Acquisition Buffering
LM358N can buffer medium-impedance analog signals in data-acquisition systems and provide gain before or after an external analog-to-digital converter. The dual package helps implement two buffered channels or a gain-plus-buffer arrangement. The verified 1 MHz nominal bandwidth is sufficient for many slow industrial-control signals, but it does not guarantee precision ADC performance: offset, bias current, settling, common-mode range, output swing, and noise must be evaluated for the actual sample rate and source impedance. Use short traces, suitable bypassing, and an ADC input network selected for the converter's acquisition requirements.
Recomendado
Communication Interface Circuits
LM358N is suitable for many low-frequency communication-interface support circuits, such as receive-path amplification, threshold detection, line-driver interfacing, and impedance buffering. Its dual architecture can combine a receive amplifier with a transmit or control amplifier in one DIP package. The verified family description supports operation from a single supply over a wide voltage range, which is useful in embedded systems. The device is not automatically a high-speed communications part: compare the approximately 1 MHz bandwidth, slew rate, input and output ranges, noise, and supply requirements with the interface standard and cable or network timing.

Notas de projeto
The verified sources identify a 32 V device rating but do not provide a complete operating-region table for the exact LM358N orderable part. Before applying a supply voltage, verify the selected manufacturer's absolute maximum and recommended operating ratings. Keep the signal within the common-mode input range and ensure the output can swing far enough for the load; do not interpret the 32 V rating as permission to use any input or output voltage at 32 V.
Place the device and its decoupling network close to the relevant analog and power pins. Use the exact manufacturer-recommended supply-bypass arrangement and maintain short ground returns. Because the verified sources do not provide a unified recommended capacitor value or layout drawing, treat capacitor selection as a datasheet-dependent step. For high-gain or high-impedance circuits, reduce parasitic capacitance and leakage, and keep sensitive input nodes away from switching and power-conversion paths.
Do not substitute LM324 for LM358N without redesigning the circuit: LM324 is a four-amplifier device rather than a dual LM358N, and the supplied comparison material explicitly warns that they are not pin-compatible in the general case. Likewise, verify the manufacturer logo and exact ordering suffix because STMicroelectronics, onsemi, Texas Instruments, Motorola, NXP, and other sources use LM358-family markings with potentially different specifications and documentation.
Informações de conformidade
The supplied web results do not provide verified compliance statements for the exact LM358N manufacturer variant. Compliance must be confirmed using the selected manufacturer's current product documentation.
