LM358PE4 - Dual 700 kHz Op Amp, 8-PDIP | Texas Instruments
부품 번호: LM358PE4 ✓ 활성LM358PE4 개요
An operational amplifier is a voltage-feedback analog IC that uses differential input voltage to produce an amplified output voltage. Operational amplifiers belong to the amplifier hierarchy, support precise closed-loop operation when paired with external resistors, and are widely used in industrial controls, sensor interfaces, audio electronics, and power-management systems. The LM358PE4 belongs to the industry-standard LM358 family and combines two amplifiers in one package.
Key electrical characteristics include a typical input offset voltage of 300 µV, a low 0.7 mA supply-current drain that is independent of supply voltage, and a common-mode input voltage range that includes ground. These features suit battery-powered, sensor-driven, and single-supply circuits where low cost, ground-referenced inputs, and two amplifiers in one package are important. The device also supports high differential input voltage capability for cost-sensitive applications.
The LM358PE4 uses a bipolar voltage-feedback architecture and is specified for general-purpose analog signal processing. Its 700 kHz gain-bandwidth product makes it suitable for low-frequency audio, control, and instrumentation tasks rather than high-speed precision applications. With a 0.3 V/µs slew rate, it can produce larger output transitions more slowly than modern rail-to-rail CMOS amplifiers, so designers should check bandwidth, output swing, and stability requirements before increasing closed-loop gain.
Typical applications include two-channel sensor conditioning, low-frequency active filters, audio preamplification, comparators, and industrial control interfaces. In each case, the two amplifiers can process independent signals or form a cascaded signal chain. Stable operation also requires suitable bypassing, careful grounding, and output-load consideration because the LM358PE4 is not a rail-to-rail-input or rail-to-rail-output device.
For single-supply designs, bias the non-inverting input above ground and use decoupling close to the supply pins. Check the common-mode and output-voltage limits against the actual signal range, and avoid relying on output saturation as a precise comparator function. Prototype the gain, slew rate, and capacitive-load behavior before committing a high-volume design.
This page combines the manufacturer specifications, package and pin information, supported alternatives, application guidance, and design notes needed to evaluate the LM358PE4. It also organizes replacement and selection questions around the verified 8-PDIP footprint, 700 kHz bandwidth, 0.3 V/µs slew rate, and 36 V maximum total supply capability.

일반적인 애플리케이션
LM358PE4 적합 용도: 6 애플리케이션s: Dual-Channel Sensor Conditioning, Industrial Control and Actuator Interfaces, Low-Frequency Active Filters, Audio Preamplification, Battery-Powered Monitoring Circuits, Comparator and Threshold Circuits.
Dual-Channel Sensor Conditioning
The LM358PE4 fits two independent sensor-signal conditioning paths because it integrates two amplifiers in one 8-PDIP package. Its 700 kHz gain-bandwidth product supports low- to mid-band instrumentation signals, while the common-mode input range that includes ground simplifies conditioning for sensors referenced to 0 V. Each channel can use standard resistor feedback to establish gain and filtering. The design should provide supply bypassing close to the device and keep the input common-mode voltage within the specified range. Because the output does not swing fully rail to rail, leave output headroom for the sensor interface and downstream converter.
추천
Industrial Control and Actuator Interfaces
The LM358PE4 is useful in industrial control interfaces that require low-frequency error amplification, current-to-voltage conversion, or actuator-drive stages. Its 0.3 V/µs slew rate is appropriate for moderate signal transitions, and the 3 V to 32 V total supply range supports both lower-voltage logic-side circuits and higher-voltage industrial rails when the remaining device limits are respected. Two amplifiers can form a cascaded control path or serve separate feedback and drive functions. Maintain low-impedance grounding, protect inputs from transients, and verify the output current and voltage swing before driving loads.
추천
Low-Frequency Active Filters
The LM358PE4 can implement first- and second-order low-frequency active filters in audio, measurement, and control systems. Its 700 kHz gain-bandwidth product provides ample closed-loop bandwidth for filters below the audio range, while two amplifiers allow a Sallen-Key stage or two independent channels. Stable operation depends on correct resistor ratios, suitable capacitor tolerances, and keeping source and load impedances within the amplifier's capabilities. Avoid designs that require rail-to-rail output swing, and check the resulting filter response across temperature because bipolar input-offset and bias-current behavior can shift the operating point.
추천
Audio Preamplification
The LM358PE4 is appropriate for modest audio preamplification when a bipolar general-purpose amplifier and low cost are priorities. The two amplifiers can provide independent left and right channels, and the 700 kHz gain-bandwidth product comfortably covers conventional audio-band signal paths. Its common-mode range includes ground, which simplifies single-supply operation with a mid-supply signal bias. Designers should account for the 0.3 V/µs slew rate during large transients and avoid driving low-impedance headphones directly. Add input attenuation or a buffer when source impedance is high or distortion requirements are stringent.
추천
Battery-Powered Monitoring Circuits
The LM358PE4 can serve low-frequency monitoring and alarm functions in battery-powered equipment because its typical supply-current drain is 0.7 mA and is independent of supply voltage. Two internal amplifiers can compare a sensor signal with a threshold and buffer the result without requiring two packages. The common-mode input range includes ground simplifies battery-rail sensing, although output swing and input limits must be checked at the minimum supply voltage. Use a stable reference for thresholds, maintain adequate bypass capacitance, and account for input-offset voltage in low-current sensor systems where a few hundred microvolts can affect the decision point.
추천
Comparator and Threshold Circuits
The LM358PE4 can perform basic threshold detection when its open-loop behavior is intentionally used and the output operating limits are respected. The two amplifiers allow one channel to sense a sensor threshold while the other buffers or amplifies the result. The 700 kHz bandwidth and 0.3 V/µs slew rate are more than adequate for slow thresholds, and the common-mode range that includes ground helps with single-supply sensing. A dedicated comparator may be preferable when low propagation delay, rail-to-rail inputs, or an open-drain output is required. Confirm output saturation levels and avoid using the op amp as a precision comparator without characterization.

설계 노트
Place the supply bypass capacitor close to the positive supply pin and keep the ground return path short and low impedance. The LM358PE4 is a through-hole device, but the surrounding high-frequency loop still requires a compact layout. Avoid routing long traces beside noisy switching nodes, and place input and feedback components so their connections remain short. Confirm the physical orientation and pin numbering against the manufacturer pin-description table before fabrication.
Do not assume rail-to-rail input or output behavior. Although the common-mode input range includes ground, the operating input range and output swing remain constrained, particularly at low supply voltages. For a single 5 V supply, bias the signal above ground and calculate the maximum signal excursion before selecting feedback resistors. Also check output current and capacitive-load limits when driving long cable or ADC input networks.
Use the 700 kHz gain-bandwidth product to calculate the usable closed-loop bandwidth at the intended noise gain. As closed-loop gain increases, bandwidth decreases, while the 0.3 V/µs slew rate sets a separate full-power-bandwidth limit. Add compensation for capacitive loads when necessary and keep feedback loops physically compact. Validate stability with the actual source impedance, load, and cable because the open-loop response of the package and board can affect the result.
Estimate dissipation from the actual supply voltage, output voltage, and load current before release. The formula is P = (VIN - VOUT) × ILOAD plus the small supply-current contribution. A 12 V input, 5 V output, and 10 mA load produces an estimated 70 mW regulator loss, while the same conditions at 100 mA produce approximately 700 mW. Apply the estimate using those stated input values and verify the resulting junction temperature against the device limits.
