LM358DE4 - 700kHz Dual Op Amp, 16V | Texas Instruments
料号： LM358DE4 ✓ 量产中LM358DE4 概述
An operational amplifier, or op amp, is a high-gain differential amplifier that uses negative feedback to amplify the difference between two input voltages. The LM358 belongs to the broader hierarchy of operational amplifier, analog amplifier IC, and semiconductor. Its dual-channel architecture provides two amplifiers in one package, reducing board area when two related analog functions are required. Unlike precision rail-to-rail amplifiers, the LM358 uses bipolar transistor circuitry and is therefore especially familiar in supply-voltage-oriented industrial, instrumentation, and control designs.
Key characteristics include two amplifier circuits, a 700 kHz gain-bandwidth product, and a 16 V maximum supply identified by the manufacturer-oriented product information. The 8-SOIC package uses eight terminals in a rectangular surface-mount gull-wing format. Its dual-channel organization is useful for signal conditioning, buffering, current sensing, analog measurement, filtering, and precision-control circuits where two amplifiers share the same supply and ground references.
The 700 kHz gain-bandwidth product makes the LM358 suitable for general-purpose closed-loop amplifier stages operating at low-to-moderate signal frequencies. In a non-inverting configuration, closed-loop bandwidth depends on the selected feedback network rather than the open-loop gain-bandwidth product alone. The bipolar implementation also supports operation from a single positive supply, allowing input and output signals to be referenced toward ground in many industrial and embedded analog circuits.
Typical applications include sensor-signal conditioning, transducer buffering, active filtering, low-side current sensing, analog control loops, and general measurement boards. Two channels can implement differential signal conditioning, active filters, comparator-style threshold conditioning with suitable feedback arrangements, or independent amplifier stages sharing the same supply. The SOIC package is also convenient for prototype boards and production assemblies that use conventional surface-mount footprints.
Design attention should focus on input common-mode range, output swing, load capability, and stability with the selected feedback network. Decoupling capacitors should be placed close to the supply pins, and sensitive analog traces should be kept away from switching nodes. Because the device is not rail-to-rail at its inputs and outputs, verify signal levels against the operating supply before using it in low-voltage battery systems.
This page organizes the LM358DE4 specifications, pin and package information, application guidance, and pin-compatible alternatives into one engineering-focused reference. It also provides practical selection criteria for comparing the standard LM358 family with alternate dual-amplifier implementations before committing a PCB footprint to production.

典型应用
LM358DE4 适用于 6 应用s: Sensor Signal Conditioning, Low-Side Current Sensing, Active Analog Filters, Transducer Buffering, Precision Control Loops, Analog Measurement Front Ends.
Sensor Signal Conditioning
LM358DE4 suits sensor-signal conditioning because its two amplifier channels can amplify or filter related sensor outputs while sharing an 8-SOIC package. The 700 kHz gain-bandwidth product is appropriate for general-purpose conditioning of comparatively slow industrial and instrumentation signals. One channel can provide gain while the other performs filtering or buffering. Because the device is not rail-to-rail, verify that the sensor voltage and conditioned output remain within the allowed common-mode and output-swing ranges.
Low-Side Current Sensing
A low-side current-shunt amplifier is a practical LM358DE4 application because the device supports two independent general-purpose amplifier channels. One channel can amplify the small shunt voltage, while the second can add filtering or amplify a related sensor. The 700 kHz gain-bandwidth product supports bandwidths suitable for many measurement loops rather than high-speed signal instrumentation. Confirm the shunt common-mode voltage, required output range, and stability of the selected gain configuration.
Active Analog Filters
LM358DE4 can implement active low-pass, high-pass, or band-pass filter stages where economical dual-channel analog conditioning is useful. Its 700 kHz gain-bandwidth product provides useful bandwidth for general-purpose control and measurement systems, and the second channel can form another filter pole. Component tolerances and the op amp's finite gain and bandwidth determine the final response, so simulate the closed-loop network and check stability across the intended load and signal range.
Transducer Buffering
LM358DE4 works as a transducer buffer when a sensor produces a signal that requires isolation from a higher-impedance measurement or ADC input stage. The 700 kHz bandwidth is more than adequate for many temperature, pressure, position, and level sensors with limited bandwidth. Using two channels can buffer two complementary or redundant sensor outputs. Check the input bias current, offset voltage, input common-mode range, and capacitive loading because the selected sensor impedance can materially affect amplifier accuracy.
Precision Control Loops
LM358DE4 can serve as an error amplifier in general-purpose industrial control loops where a 700 kHz gain-bandwidth product and dual-channel packaging are useful. One channel may amplify an error signal while the other buffers a reference or feedback measurement. The bipolar amplifier architecture is compatible with conventional control-system signal levels. Confirm loop stability, output drive, supply headroom, and allowable input common-mode voltage; compensation components may need adjustment when replacing another dual amplifier.
Analog Measurement Front Ends
LM358DE4 is applicable to analog measurement boards requiring signal gain, reference buffering, and channel conditioning in one compact 8-SOIC package. Its two channels can process complementary outputs, implement a differential measurement front end, or combine amplification and filtering. The 700 kHz gain-bandwidth product supports many slow industrial measurement channels, while the 16 V maximum supply accommodates conventional laboratory and control voltages. Validate offset, bias current, output swing, and accuracy across the required temperature range.

设计说明
The LM358DE4 is specified for a maximum 16 V supply and is not a rail-to-rail input or output device. Keep signal amplitudes inside the permitted common-mode and output-swing regions, especially in 5 V systems. Place a small bypass capacitor close to each supply terminal and provide adequate decoupling between the two amplifier sections so supply ripple does not degrade measurement accuracy.
Use the manufacturer pin-description table when laying out the 8-SOIC footprint. Keep the two amplifier channels functionally separated where one channel handles a sensitive sensor and the other drives a switching or higher-current stage. Route output pins away from input and reference traces to reduce parasitic feedback, and place the feedback resistors close to the relevant amplifier inputs.
Do not assume that every part marketed as an LM358 equivalent has identical input bias current, offset voltage, common-mode range, output swing, noise, or temperature limits. For LM2904, MC1458, LMV358, and NE5532 substitutions, verify the exact orderable package suffix and recalculate gain stability. High source impedances can also create input-bias-current errors that are insignificant in ordinary voltage-source circuits.
The 700 kHz gain-bandwidth product makes closed-loop bandwidth dependent on the selected noise gain. Avoid excessive gain at frequencies where the amplifier cannot deliver the required phase margin, and add an isolating resistor when driving capacitive loads. If both channels share a sensor reference, check crosstalk through common supply impedance and use local decoupling rather than relying on a distant bulk capacitor.
