LM358PWG4 - Dual 700kHz Op Amp, 16V, TSSOP-8 | Texas Instruments
MPN: LM358PWG4 ✗ סוף ייצורLM358PWG4 סקירה
An operational amplifier is an analog signal-processing IC that compares its inverting and non-inverting inputs and amplifies the voltage difference between them. Within the broader semiconductor hierarchy, an op amp is an amplifier IC and part of the analog signal-conditioning family. The dual configuration in the LM358PWG4 places two general-purpose amplifiers in one package, reducing component count and board area in designs that need two similar signal-processing channels.
The key operating characteristics are a 700 kHz gain-bandwidth product, 0.3 V/us slew rate, and operation from 3 V to 32 V. The documented output-swing range extends from approximately ±1.5 V to ±16 V depending on supply conditions and load. Its general-purpose architecture makes it suitable for conventional amplifier, comparator, summing, and feedback applications where moderate bandwidth and broad supply compatibility are more important than rail-to-rail input or output operation.
The LM358 family is particularly useful when two independent channels can share a common supply. Because both amplifiers are in the same package, board designers can shorten supply routing and maintain symmetrical placement of the two channels. The 8-pin TSSOP package also supports compact PCB construction, although its narrow lead pitch requires careful assembly and adequate solder-joint inspection.
Typical uses include audio preamplification, sensor-signal conditioning, low-frequency active filters, comparators with pull-up resistors, and general instrumentation. In these applications, the 700 kHz bandwidth handles low- and mid-frequency signals, while the 0.3 V/us slew rate helps control distortion for moderate-amplitude signals. The broad 3 V to 32 V supply range also supports both low-voltage portable systems and higher-voltage industrial control systems.
Designers should evaluate output swing, input common-mode range, bias current, offset voltage, noise, and stability for the exact operating conditions before assigning gain or filter coefficients. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs should be biased so they remain in a defined common-mode state. The two channels are independent, but sharing a package does not guarantee matched behavior.
This product page combines the verified LM358PWG4 electrical and packaging characteristics with application guidance, replacement considerations, and practical selection criteria. It helps engineers identify where the dual 700 kHz amplifier, 3 V to 32 V supply capability, and compact TSSOP-8 package provide useful design advantages without overlooking rail-range or precision requirements.

יישומים טיפוסיים
LM358PWG4 מתאים עבור 6 יישוםs: Low-Frequency Audio Preamplification, Industrial Sensor Signal Conditioning, Active Audio and Control Filters, Open-Collector Comparator Interface, Portable Power and Battery Monitoring, Instrumentation and Measurement Front Ends.
Low-Frequency Audio Preamplification
The LM358PWG4 is suitable for two-channel audio preamplification because its 700 kHz gain-bandwidth product comfortably covers the audio band and its 0.3 V/us slew rate supports moderate-amplitude signals. Each amplifier can provide voltage gain, inversion, or mixing around a reference bias when the supply arrangement supports bipolar signals. The 8-TSSOP package saves board area, but designers should verify output swing, input bias current, channel noise, and distortion against the source impedance and signal level.
מומלץ
Industrial Sensor Signal Conditioning
The LM358PWG4 can condition low-bandwidth sensor signals using buffers, differential amplifiers, or active filters. Its 700 kHz gain-bandwidth product is adequate for many temperature, pressure, and position sensors, while the 3 V to 32 V supply range supports both compact instrumentation and higher-voltage control systems. The 0°C to +70°C grade must remain within the enclosure's environmental limits. High-impedance sensors also require attention to input bias current and common-mode headroom.
מומלץ
Active Audio and Control Filters
The dual LM358PWG4 implementation can form two second-order active-filter sections within a 700 kHz usable signal range. Its 0.3 V/us slew rate makes it more appropriate for low-frequency and moderate-amplitude signals than for high-slew waveform shaping. Because the two channels share a package but are not guaranteed to be perfectly matched, critical precision filters should include resistor matching and consider trim or calibration. Confirm noise, offset, and stability with the final component tolerances.
מומלץ
Open-Collector Comparator Interface
When the LM358PWG4 is used as an open-collector comparator, its output requires an external pull-up resistor to establish a logic-high level. This arrangement is useful for translating analog thresholds into digital control signals while operating from the amplifier's 3 V to 32 V supply range. The 0.3 V/us slew rate determines response speed, and the approximately ±1.5 V near-rail swing must be included in the logic-interface design. Account for input offset voltage when the switching threshold is critical.
מומלץ
Portable Power and Battery Monitoring
LM358PWG4 can amplify battery or power-rail voltages in portable monitoring circuits because its minimum specified supply voltage is 3 V and the dual package contains two independent channels. One channel may amplify a divided battery voltage while the other buffers a temperature or current-sensor signal. The 700 kHz gain-bandwidth product is more than adequate for slow monitoring signals. Actual suitability depends on the battery voltage, quiescent consumption, input common-mode range, and the output swing required by the downstream converter or display.
מומלץ
Instrumentation and Measurement Front Ends
The two channels in the LM358PWG4 can support excitation buffering, differential measurement, and output conditioning in general-purpose instrumentation. Its 700 kHz bandwidth accommodates many slow measurement systems, and the 3 V to 32 V supply range offers flexibility across laboratory and industrial equipment. For precision work, evaluate input offset voltage, input bias current, noise, and channel matching. The 0°C to +70°C specification limits uncontrolled environments, while LM2904PW may be preferable where a broader temperature range is needed.

הערות תכנון
Decouple each supply connection with a local ceramic capacitor and place the components directly beside the package power pins. For a single-supply circuit, treat the lower rail as ground and verify that the input and output signals remain inside the amplifier's common-mode and swing limits. With a 3 V supply, the approximately ±1.5 V near-rail output limitation can materially reduce usable signal range, so biasing or a higher supply voltage may be necessary.
Route each amplifier's feedback components close to its input and output pins, and keep the two channels physically separated where independent noise or heat is important. The TSSOP-8 lead pitch requires accurate pad geometry, adequate solder mask definition, and inspection of completed joints. Maintain a direct return path from each bypass capacitor to the appropriate ground pin, and avoid routing high-current or switching-node copper beneath the analog package.
Do not assume that the full 3 V to 32 V supply range is also a valid input or output range. Check the common-mode input range, output swing, offset voltage, bias current, and stability for the selected closed-loop gain. Also avoid leaving an unused amplifier input floating; bias it into a defined state so that input bias current does not move the unused output unpredictably. The two channels share a package but are not guaranteed to be perfectly matched.
מידע על תאימות
The available product information identifies LM358PWG4 as a Texas Instruments dual operational amplifier in an 8-TSSOP tube package but does not provide explicit compliance declarations. RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals status therefore remain unknown.
