LM358FVJ-E2 - Dual Ground-Sense Op Amp | ROHM Semiconductor
N.º da peça: LM358FVJ-E2 ✗ Fim de vidaLM358FVJ-E2 Visão geral
An operational amplifier is a voltage amplifier with high open-loop gain, negative feedback, and high input impedance. Used as a non-inverting or inverting amplifier, it can amplify a differential input voltage while presenting a high impedance to the source. The dual-channel configuration of the LM358FVJ-E2 provides two amplifiers in one package, reducing board area in circuits that need more than one gain stage.
The ROHM product page identifies the device as a ground-sense operational amplifier, and distributor information describes it as a standard general-purpose amplifier with two circuits. Its stated 3 V to 32 V operating range supports both low-voltage systems and higher-voltage industrial signal chains when the complete circuit, including input and output limits, is designed accordingly. The -E2 ordering code identifies the specified supplier packaging configuration.
Ground-sense operation is important when a measured signal is referenced close to ground or where the input source has low voltage headroom. The amplifier should be configured with suitable feedback, decoupling, and output-voltage headroom. Because this page does not reproduce the complete electrical characteristic table, designers should verify offset voltage, input bias current, output swing, slew rate, noise, and common-mode behavior against the current ROHM datasheet before production release.
Typical uses include low-level signal conditioning, current-sense amplifier sections, sensor interfaces, feedback networks, analog control loops, and general dual-amplifier boards. The 8-TSSOP-BJ package is particularly useful for compact industrial, instrumentation, and embedded-control assemblies where two independent amplifier channels are required without allocating two separate packages.
Start the design by confirming the pin mapping for the exact FVJ and -E2 ordering codes. Place the supply-decoupling capacitor close to the device, maintain a defined ground reference, and review output-swing limits against the expected signal range. The product page marks LM358FVJ-E2 as not recommended for new designs, so it is primarily appropriate for existing designs, controlled maintenance, and previously qualified production programs.
This product summary combines the manufacturer product designation, distributor package and supply-range information, lifecycle status, application guidance, and a conservative review of what engineers must confirm before releasing a new PCB. It supports faster sourcing and design triage while directing critical decisions back to the official manufacturer documentation.

Aplicações típicas
LM358FVJ-E2 é adequado para 6 aplicaçãos: Ground-Referenced Sensor Signal Conditioning, Current-Sense Amplifier Front End, Industrial Feedback Control Loop, Low-Level Analog Signal Amplification, Instrumentation Buffering, Embedded Analog Interface Board.
Ground-Referenced Sensor Signal Conditioning
The LM358FVJ-E2 fits ground-referenced sensing circuits because ROHM identifies it as a ground-sense operational amplifier and provides two channels in one 8-TSSOP-BJ package. One channel can amplify a sensor signal referenced to ground, while the other can provide feedback, level conditioning, or an additional measurement path. The stated 3 V to 32 V operating range supports multiple supply architectures, but the design must remain within the datasheet input common-mode and output-swing limits. Confirm offset, noise, bias current, and stability requirements before using the device for high-accuracy measurements.
Current-Sense Amplifier Front End
A dual ground-sense amplifier can support a current-measurement front end by amplifying the small voltage developed across a sense resistor and then providing a second channel for filtering or offset-related conditioning. The LM358FVJ-E2 operates from 3 V to 32 V and offers two amplifier circuits in a compact 8-TSSOP-BJ package. Input bias current and offset must be checked against the shunt resistance, while output swing must remain compatible with the downstream converter or controller. Stable feedback-network layout is essential to preserve the intended gain and bandwidth.
Industrial Feedback Control Loop
The LM358FVJ-E2 is suitable as an error amplifier in an industrial analog-control loop where two channels can be assigned to a main control function and a feedback or monitoring path. Its dual-circuit organization reduces the number of amplifier packages required on a compact controller board, and its 3 V to 32 V supply range accommodates many 24 V-class control environments when the detailed operating limits permit it. Validate common-mode range, output current, slew rate, and stability at the intended gain. The not-for-new-design status should be checked against the product qualification plan.
Low-Level Analog Signal Amplification
For low-level voltage amplification, the LM358FVJ-E2 provides two standard general-purpose amplifier channels that can be configured as inverting or non-inverting stages using external resistors. Its ground-sense orientation makes it particularly relevant to signals referenced close to the system ground, while the 8-TSSOP-BJ package helps minimize board area. Verify input offset voltage, input bias current, noise, open-loop gain, and output swing against the signal amplitude and source impedance. Use short feedback paths and a stable reference plane to minimize offset and sensitivity to layout parasitics.
Instrumentation Buffering
The LM358FVJ-E2 can contribute to instrumentation circuits where two amplifier channels are needed for buffering or gain stages around sensors and measurement inputs. Its 3 V to 32 V operating range provides flexibility for laboratory and process-control equipment, while the compact dual TSSOP outline supports denser analog boards. Ground-referenced source signals must remain inside the input common-mode range, and the output must have enough swing for the receiver. Review noise and offset when driving a high-impedance back end, and avoid using the generic dual amplifier as a precision instrumentation amplifier without careful offset, bias-current, and drift analysis.
Embedded Analog Interface Board
The LM358FVJ-E2 can provide general analog interface functions on an embedded-control board, including signal amplification, actuator feedback, threshold conditioning, and dual-channel sensing. Two channels in an 8-TSSOP-BJ package reduce routing overhead compared with two separate amplifier packages, while the broad 3 V to 32 V supply range can simplify architecture selection. Place supply bypassing near the pins, maintain a low-impedance ground return, and verify logic-interface levels through the output swing. For new embedded platforms, confirm lifecycle approval and consider a dual amplifier explicitly marketed for new designs.

Notas de projeto
Treat the 8-TSSOP-BJ outline as a fixed PCB footprint and verify it against the current package drawing before releasing artwork. Place the supply-decoupling capacitor adjacent to the power and ground pins, provide a short and low-impedance ground return, and route the two channels to minimize shared copper resistance. If the two amplifier sections carry different signals, keep their feedback components and traces physically separated to reduce crosstalk and parasitic feedback.
Do not assume that every LM358-family ordering code is mechanically interchangeable. The FVJ package identifier, 8-TSSOP-BJ outline, -E2 ordering suffix, pin orientation, and exposed or lead-frame details must all be checked before substitution. Also confirm the input common-mode range and output swing at the actual 3 V to 32 V operating conditions; a valid supply voltage alone does not guarantee linear operation.
Use short, direct feedback paths and keep high-impedance input nodes away from switching nodes, inductors, and the supply-decoupling return. For sensor interfaces, use a quiet ground reference and avoid routing the input beside ground-current paths. Evaluate stability with the actual resistive and capacitive loads, and include the output-load limits from the manufacturer datasheet when driving cables, ADC front ends, or capacitive loads.
Informações de conformidade
ROHM marks the LM358FVJ-E2 as not recommended for new designs. RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals status must be confirmed from the current manufacturer product documentation.
