LM358ADE4 - Dual General-Purpose Op Amp | Texas Instruments
料号： LM358ADE4 ✓ 量产中LM358ADE4 概述
An operational amplifier is an analog integrated circuit that uses high open-loop gain and negative feedback to amplify a voltage difference between its input terminals. In the broader hierarchy, an operational amplifier is a linear amplifier and analog signal-processing IC used within instrumentation, control, sensor, communications, and power-management systems. The LM358 family is associated with two amplifiers per package, making it useful where board area or component count matters.
The LM358ADE4 provides a 700 kHz gain-bandwidth product, a 0.3 V/us slew rate, and two amplifier circuits in an 8-SOIC package. The wide SOIC body measures 0.154 inches, or 3.90 mm, in width according to the part listing. These characteristics suit moderate-bandwidth analog signals rather than demanding high-speed waveform or video applications. Each internal amplifier can be configured independently for standard inverting, non-inverting, summing, and feedback-based signal-conditioning circuits.
The 8-SOIC package provides widely separated input, output, and power connections on a conventional surface-mount footprint. Its dual-channel architecture reduces the number of packages needed when two independent gain stages, two comparators, or mixed analog functions are required. The device is identified by Texas Instruments as an industry-standard dual operational amplifier, supporting design familiarity and straightforward board-level integration where the LM358 family is already qualified in the design.
Typical uses include low-frequency sensor amplification, industrial control signals, audio preamplification, power-supply feedback loops, active filters, and general instrumentation. Two amplifiers in one package can also support comparator-style operation when saturation and switching behavior are acceptable. Because the gain-bandwidth product is 700 kHz, the device is better suited to modest signal bandwidth than precision audio or communications paths requiring substantially faster amplifiers.
Design the surrounding feedback network to establish the intended closed-loop gain and bandwidth. Check output swing, input common-mode range, supply voltage, offset, input bias current, and output-current requirements in the manufacturer datasheet before finalizing the circuit. Place input and output components close to their associated pins, maintain a quiet supply path, and check that the selected SOIC footprint, pin orientation, and tube ordering code match the assembly process.
This product page combines the exact ordering information, package characteristics, operating bandwidth, pin-compatible family alternatives, and practical design guidance needed to plan an LM358ADE4-based analog circuit before component sourcing and PCB layout.

典型应用
LM358ADE4 适用于 6 应用s: Industrial Sensor Signal Conditioning, Audio Preamplification, Power-Supply Feedback and Control, Active Filters and Integrators, Data Acquisition and Instrumentation, Portable and Battery-Powered Controls.
Industrial Sensor Signal Conditioning
The LM358ADE4 fits low- and medium-bandwidth industrial sensor conditioning because its two 700 kHz amplifier circuits can amplify, invert, or buffer two related channels in one 8-SOIC package. A typical implementation places one amplifier in a non-inverting configuration and the other in an inverting stage for gain and filtering. The 0.3 V/us slew rate supports moderate signal transitions, but the designer must confirm input common-mode range, offset, bias current, and output swing against the sensor and supply voltages. Decoupling capacitors should be located close to the power pins, and sensitive feedback resistors should be positioned to minimize parasitic pickup.
推荐
Audio Preamplification
LM358ADE4 can provide modest-bandwidth audio preamplification when the source impedance, required gain, and output loading are compatible with a 700 kHz gain-bandwidth product. Its two amplifiers allow a balanced preamplifier, mixer, or buffered input architecture in one 8-SOIC package. The 0.3 V/us slew rate is adequate for many lower-frequency audio paths but can become a limiting factor at high level and frequency. According to the Texas Instruments LM358 datasheet, input offset, bias current, noise, common-mode range, and output swing should be checked before selecting feedback and coupling components.
推荐
Power-Supply Feedback and Control
The LM358ADE4 is useful in power-supply feedback, error-amplifier, and slow control loops because it combines two amplifiers with a 700 kHz gain-bandwidth product. One channel can perform error comparison while the other shapes compensation or provides an auxiliary buffered signal. The 8-SOIC package supports conventional surface-mount assembly, while the 0.3 V/us slew rate suits moderate control-loop dynamics. Before using the device in a compensation path, confirm the loop crossover frequency, output swing, supply range, and stability behavior against the manufacturer electrical-characteristics tables.
推荐
Active Filters and Integrators
LM358ADE4 can implement active low-pass, high-pass, band-pass, and integrator stages because its 700 kHz gain-bandwidth product provides useful bandwidth above typical low-frequency filter requirements. Two amplifiers in one 8-SOIC package simplify two-pole filter or cascaded single-pole arrangements. The 0.3 V/us slew rate influences large-signal behavior, while input offset and bias current can affect precision at the lowest frequencies. Keep input bias paths and feedback components close to the relevant pins, verify resistor values against the datasheet gain equations, and simulate the complete closed-loop response.
推荐
Data Acquisition and Instrumentation
The LM358ADE4 is appropriate for moderate-bandwidth instrumentation stages that require two amplifiers but do not need rail-to-rail inputs or outputs. Common uses include sensor buffering, excitation-return amplification, and signal conditioning before an ADC. Its 700 kHz gain-bandwidth product allows useful closed-loop bandwidth at practical gains, while the dual 8-SOIC package reduces board area. The design must account for the input common-mode range relative to the sensor output, offset across the required temperature range, and the ADC input range. Add local supply bypassing and maintain a quiet reference return to avoid converting switching noise into measurement error.
推荐
Portable and Battery-Powered Controls
LM358ADE4 can support low-frequency control and signal-shaping functions in portable equipment where a dual amplifier package saves board area. The two channels can handle independent gain or comparator-like stages, provided the application's saturation and recovery behavior are acceptable. Its 700 kHz gain-bandwidth product is well above many control-signal frequencies, and the 0.3 V/us slew rate helps avoid slew-limited control responses. Confirm the minimum supply voltage, quiescent-current impact, common-mode range, and output drive against the battery voltage. A dedicated low-power alternative may be preferable when battery life dominates every other design consideration.

关键差异点
- Two general-purpose amplifiers are integrated in one 8-SOIC package （对比 LM2904PWR)

- A 700 kHz gain-bandwidth product supports moderate-bandwidth signal conditioning （对比 LM2904PWR)
设计说明
Do not treat every LM358 ordering suffix as mechanically interchangeable with LM358ADE4. The target uses an 8-SOIC tube configuration, while related codes may use a different package, temperature grade, or delivery format. Compare the manufacturer package drawing, pin table, operating-temperature rating, and supply range before substitution. In particular, verify that any 8-SOIC alternative uses the same pin numbering and exposed-pad arrangement, if present.
Place the input, feedback, and compensation components close to the associated LM358ADE4 pins to minimize parasitic capacitance and feedback-loop area. Keep both amplifier channels' ground returns short and connect them to a low-impedance ground plane. Supply bypassing should be located near the device, and analog signal traces should remain away from switching nodes and high-current return paths. These layout practices are especially important because the device's 700 kHz gain-bandwidth product can couple unwanted board noise into higher-gain stages.
Validate the entire analog signal path against the LM358ADE4 common-mode and output-swing limits before selecting amplifier gain. A 0.3 V/us slew rate is often adequate for low-frequency signals but can limit large-signal behavior even when the closed-loop bandwidth appears sufficient. Use the manufacturer electrical-characteristics curves to select the usable output amplitude and frequency combination, and provide local bypassing to minimize supply ripple coupled into the amplifier output.
