LM358MX - Dual Operational Amplifier | Texas Instruments
MPN： LM358MX ✓ 啟用中LM358MX 概覽
What is an operational amplifier? An operational amplifier is an analog active device that amplifies the difference between two input voltages while using feedback to control gain and bandwidth. A dual operational-amplifier package contains two amplifier channels and is classified as an amplifier IC within the broader semiconductor hierarchy. LM358-family devices are often considered for sensor conditioning, signal buffering, and low-frequency analog control, but the precise suitability of LM358MX for a particular application depends on verified specifications such as input common-mode range, output swing, supply current, offset voltage, slew rate, and noise.
The available data does not identify the MPN suffix, package drawing, pin configuration, or ordering details. The LM358 suffix commonly denotes an SOIC-8-style variant, but that package identification is not present in the supplied verified records and therefore requires confirmation. The absence of verified data also prevents a reliable comparison with related LM358, LM2902, or competing dual-amplifier variants.
Typical design evaluation should begin with the manufacturer's LM358MX datasheet and pinout. Review the recommended operating conditions, absolute maximum ratings, electrical characteristics, common-mode range, output-swing limits, and stability requirements. Confirm the exposed or non-exposed package dimensions and the PCB land pattern rather than relying on the MPN suffix alone.
Applications commonly investigated for a dual operational amplifier include DC signal conditioning, transducer interfaces, active filtering, and low-frequency analog signal chains. These uses remain provisional until the LM358MX electrical limits, package geometry, and temperature ratings are verified. This page intentionally distinguishes confirmed sourcing information from engineering claims that still require datasheet confirmation.
This page provides a structured place to compare the MPN, assess unavailable datasheet fields, identify same-family drop-in options, and review practical selection questions. For a production decision, use the manufacturer datasheet and current authorized-distributor inventory rather than inferred suffix data. The verified records were retrieved on 2026-10-29, but the underlying web-search operation returned a timeout and no component-specific result.

典型應用
LM358MX 適用於 6 應用s: Industrial Sensor Signal Conditioning, Active Low-Frequency Filtering, Transducer Interface Amplifier, Battery-Powered Monitoring Circuit, Audio and Communication Buffering, Embedded Control Feedback Network.
Industrial Sensor Signal Conditioning
The LM358MX can be evaluated as the amplifier in an industrial sensor-conditioning stage that converts a low-level sensor voltage into a signal suitable for an ADC. A dual amplifier also allows one channel to condition the sensor while the other handles a reference or gain stage. This use is provisional because the supplied records do not verify the LM358MX input common-mode range, offset voltage, input bias current, output swing, or supply limits. Confirm those ratings in the manufacturer datasheet and ensure the sensor output remains inside the linear operating region over the complete process range. Temperature drift, electrical noise, and the ADC input range should also be reviewed before production release.
推薦
Active Low-Frequency Filtering
LM358MX may be considered for an active low-frequency filter in a control, instrumentation, or embedded measurement system. The two channels can implement a second-order section or separate low-pass and high-pass functions, provided the verified unity-gain bandwidth, slew rate, and phase-margin behavior are adequate. The available source record contains no LM358MX bandwidth or stability information, so this application requires datasheet confirmation. Calculate resistor tolerances, capacitor tolerances, and expected gain error against the target filter response. Prototype the complete filter because amplifier noise, offset, loading, and supply variation can change attenuation and phase characteristics.
推薦
Transducer Interface Amplifier
A dual operational amplifier can be used to build a transducer interface with differential sensing and an output stage. LM358MX is a candidate only if its verified input bias current, offset voltage, common-mode capability, and output swing support the transducer and excitation arrangement. The supplied records did not return those ratings, and they did not identify the exact package pinout, so engineers must not finalize a schematic or PCB from family-level assumptions. Check offset drift, noise, supply rejection, and behavior near the ends of the input range. The same datasheet revision used for the drop-in decision should also be used for production inspection and change control.
推薦
Battery-Powered Monitoring Circuit
LM358MX may fit a battery-powered monitoring circuit that conditions a sensor or compares a divided battery voltage against a threshold. Such designs benefit from a low supply voltage, but the actual LM358MX operating range and quiescent current were not included in the supplied records, so battery-life calculations cannot be completed from this page. Verify the minimum supply voltage, quiescent current, output swing, and whether the input common-mode range covers the battery’s useful discharge interval. Consider output behavior during shutdown and ensure that a rail-to-rail input signal does not create an unintended load or false measurement.
推薦
Audio and Communication Buffering
The LM358MX can be evaluated for low-frequency audio or communication buffering when the required signal bandwidth and output loading are modest. The dual configuration can buffer two channels, although the verified records provide no noise, slew-rate, output-current, or distortion data for LM358MX. Before using it in an audio path, confirm output swing, drive capability, noise, and channel-to-channel behavior under the actual load. Avoid assuming that a family member’s published characteristic applies automatically to every ordering suffix. PCB layout should keep the amplifier feedback paths short, provide local supply decoupling, and keep sensitive high-impedance inputs away from switching and digital return currents.
推薦
Embedded Control Feedback Network
LM358MX may be used in an embedded feedback or comparator-based control network around a microcontroller or processor. One channel can amplify an error signal while the other can provide an auxiliary buffer, but the common-mode and output-range requirements depend on the rail voltages and analog signal levels. The supplied evidence does not verify those LM358MX limits, the pinout, or the package land pattern, so this use remains a design candidate rather than a released configuration. Verify startup behavior, stability around the intended feedback network, and whether the output can reach the logic threshold reliably. Use the official datasheet pin table and electrical characteristics during schematic review.

主要差異化特點

- Explicit unavailable-data handling improves release traceability (對比LM358P)
設計說明
Do not release the PCB footprint until the exact LM358MX orderable code, package drawing, pin numbering, and terminal dimensions have been checked against the manufacturer datasheet. The supplied records contain no verified package data. Compare the land pattern mechanically with the selected manufacturer drawing, including body width, lead span, lead pitch, seating plane, and any exposed thermal pad. Confirm the pin-1 orientation and pin functions directly from the pin table. A suffix-based assumption is not sufficient because related LM358 order codes can use different package options.
Validate the complete power-supply operating region before designing around LM358MX. The verified records do not establish minimum or maximum supply voltage, quiescent current, input common-mode range, or output swing. At the system level, verify startup behavior, supply tolerance, output load, current consumption, and behavior during supply transitions. If the input signal can approach ground or the output must reach a logic threshold, explicitly check the datasheet limits rather than assuming rail-to-rail operation.
A same-family MPN is not automatically a drop-in replacement. For every proposed alternative, compare pin assignment, package dimensions, supply limits, common-mode range, output swing, offset voltage, bias current, bandwidth, slew rate, noise, temperature grade, and qualification status. Record these comparisons against controlled datasheet revisions. LM358P is particularly important to verify because related order codes may not use the same package. Any substitution must also be confirmed for lifecycle status, markings, and authorized-channel availability.
Use a layout that minimizes feedback-loop area and keeps input nodes away from digital and switching-current paths. Place the required bypass capacitors at the device power pins according to the manufacturer datasheet and follow the specified ground and return arrangement. For high-impedance sensor inputs, guard or shield sensitive traces where appropriate, keep leakage-producing board surfaces in mind, and avoid routing beneath potentially noisy power paths. The exact capacitor values and grounding arrangement must follow the verified application guidance for LM358MX.
