LM358FVM-GTR - Dual Ground-Sense Op Amp | ROHM Semiconductor
部品番号: LM358FVM-GTR ✗ 生産終了LM358FVM-GTR 概要
An operational amplifier is a voltage-gain element that compares its input signals and amplifies the difference between them. A dual operational amplifier contains two amplifier channels in one package, reducing component count and board area when a circuit requires two signal-processing paths. A ground-sense amplifier can accommodate input or output signals referenced to ground while operating from a single supply, making it useful in sensor, control, and general-purpose industrial electronics.
The LM358FVM family emphasizes low current consumption and a wide operating supply-voltage range. Its 3 V minimum single-supply operation supports low-energy systems, while operation up to 32 V provides additional headroom for industrial control voltages. Ground-sense input and output operation helps simplify designs that do not require rail-to-rail inputs or outputs. Two channels in the same package also allow related amplifier functions to share one physical footprint.
The -FVM package designation corresponds to the 8-pin MSOP outline identified for LM358FVM-GTR. A compact surface-mount package is useful in densely assembled control boards where two separate single-channel amplifiers would consume additional board area. The -GTR suffix identifies the tape-and-reel configuration used for automated assembly. Exact pin functions, electrical limits, stability recommendations, and decoupling requirements must be taken from the manufacturer datasheet before schematic capture or PCB release.
Typical uses include low-voltage sensor conditioning, industrial current or voltage monitoring, feedback networks in control systems, and general dual-amplifier signal processing. The wide supply range can simplify power architecture when a board contains both low-level sensor circuits and higher-voltage control signals, provided every connected node remains inside the device's absolute maximum and common-mode limits. For a new design, the manufacturer's NRND status makes this part primarily suitable for maintenance of an existing qualified design rather than broad new-product adoption.
Careful review of the datasheet pin description is essential because MSOP packages are compact and incorrect assignments can cause unstable operation or damage. Input and output bypassing, source and sink current, input bias behavior, output swing, common-mode range, and slew rate should all be checked against the intended operating points. The circuit should also be assessed at startup, shutdown, output short-circuit, and temperature extremes.
This product page combines the manufacturer's lifecycle notice with distributor package information, an eight-row technical specification set, application guidance, and replacement-oriented selection notes. It highlights both the useful attributes of the dual ground-sense amplifier and the practical limitation created by its not-recommended-for-new-designs status.

主な用途
LM358FVM-GTR の用途: 6 件s: Low-Voltage Sensor Conditioning, Industrial Voltage Monitoring, Control-System Feedback Amplifier, Battery-Powered Monitoring Circuit, Current-Sense Amplifier, General-Purpose Signal Conditioning.
Low-Voltage Sensor Conditioning
The LM358FVM-GTR fits dual-channel sensor-conditioning circuits that operate from a single supply between 3 V and 32 V. Its input ground-sense capability is useful when sensor outputs are referenced to ground rather than centered between two rails. The two channels can process related inputs, such as a sensor signal and a buffered reference, while the compact 8-pin MSOP preserves board area. Because the device is not recommended for new designs, engineers should verify offset, bias current, input common-mode limits, noise, and stability against the particular sensor source impedance before adopting it in a new platform.
おすすめ
Industrial Voltage Monitoring
A dual ground-sense operational amplifier can support industrial voltage-monitoring functions where inputs are referenced to ground and circuit voltages vary widely. The LM358FVM-GTR accepts a single supply from 3 V to 32 V and packages both channels in an 8-pin MSOP, allowing a compact implementation of an input buffer and companion measurement channel. Design work must include checking the common-mode input range, output swing, input bias current, and behavior at the highest monitored voltage. For new equipment, the part's NRND lifecycle status should be weighed against a currently supported amplifier.
おすすめ
Control-System Feedback Amplifier
The LM358FVM-GTR is suitable for two feedback or error-amplifier channels in a control board when the signal node is ground referenced and a single-supply power architecture is used. Its 3 V to 32 V operating range allows the same device family to interface with low-voltage sensing circuitry and higher-voltage control sections. Each channel must be stabilized for the selected gain, input and output capacitors must follow the manufacturer recommendations, and the output drive must remain within the specified limits. The compact MSOP-8 package also reduces the footprint compared with two separate single amplifiers.
おすすめ
Battery-Powered Monitoring Circuit
The low-current-consumption characteristic of the LM358FVM family makes the device relevant to battery-powered monitoring equipment operating from a 3 V to 32 V single supply. Two channels can share the same package when the design requires a monitored input and a buffered reference or threshold function. Power-budget calculations should include the quiescent current at the actual supply voltage, divider resistance, sensor standby current, and switching activity. Before using this NRND component in a new battery product, compare the total operating current and supply efficiency with a currently supported low-power dual amplifier.
おすすめ
Current-Sense Amplifier
The LM358FVM-GTR can amplify a ground-referenced current-sense signal in a compact two-channel instrumentation arrangement. Its input and output ground-sense characteristics avoid the need for a midpoint bias when the shunt voltage remains within the input common-mode range. A second channel may provide filtering, level conversion, or an independent monitor. The circuit should be evaluated for shunt impedance, amplifier bias current, offset error, output swing, and recovery after an overload. Direct-current accuracy also depends on the sense resistor and PCB layout rather than being guaranteed by the amplifier alone.
おすすめ
General-Purpose Signal Conditioning
The LM358FVM-GTR provides two general-purpose amplifier channels in one 8-pin MSOP for compact analog boards requiring buffering, gain, filtering, or comparison functions. Its single-supply operation from 3 V to 32 V is useful when a circuit includes ground-referenced signals and a conventional positive supply. Component selection for each topology must remain inside the input common-mode and output swing limits, and feedback networks should be calculated for the intended closed-loop gain. The NRND designation makes this choice most appropriate for continuity of an existing design or an approved maintenance program.

設計ノート
Use the LM358FVM package drawing and pin-description table before assigning PCB nets. The MSOP-8 footprint is compact, so route input, output, supply, and ground connections to avoid long traces and unintended coupling. Keep the two input and output nodes associated with each channel physically separate, place decoupling close to the supply pins, and connect the ground reference using a short return path.
Do not infer full rail-to-rail behavior from the single-supply and ground-sense descriptions. Verify input common-mode limits, output swing, input bias current, output drive, and absolute maximum ratings at the actual 3 V to 32 V operating range. Also check whether a selected channel topology requires external bias compensation, because incorrect bias can introduce offset error even when the signal itself is ground referenced.
Budget the amplifier's actual quiescent current at the selected supply voltage together with divider, sensor, and load currents. Low current consumption is a family-level advantage, but the precise value and temperature dependence must be taken from the manufacturer datasheet. For battery-powered equipment, calculate the average and peak current over the operating duty cycle, and verify startup behavior across the full supply range.
For current-sense and sensor applications, keep the high-impedance input route short and isolate it from output and switching nodes. Place sense-resistor or source components so their parasitic resistance does not create an unintended gain error. A solid ground plane, symmetrical input routing, and controlled output feedback placement can reduce offset pickup and improve repeatability. Confirm whether the exposed thermal feature requires a copper pad and thermal-via pattern.
