LM358PWRG3 - Dual 16V 700kHz Op Amp | Texas Instruments
MPN: LM358PWRG3 ✓ Hoạt độngLM358PWRG3 Tóm tắt
An operational amplifier is a high-gain, differential-input analog IC used to amplify voltage differences. In its broader hierarchy, an operational amplifier belongs to the amplifier-IC and analog-signal-chain categories. A dual op amp integrates two amplifier channels into one package, allowing a design to use both channels for related tasks such as signal conditioning, buffering, filtering, or feedback control. The LM358PWRG3 combines that two-channel architecture with a compact TSSOP-8 footprint.
The identified part is a standard, general-purpose device rather than a rail-to-rail precision amplifier. Its stated 700 kHz gain-bandwidth product supports applications where the closed-loop bandwidth is substantially lower after accounting for the selected noise gain. The 16 V maximum supply rating places the device in the single-supply operating class shown by the product listing. Tape-and-reel packaging supports automated pick-and-place and high-density PCB assembly.
The dual-channel organization can reduce component count when a board needs two related amplifier functions. One channel might condition a sensor output while the other provides buffering or active feedback, although the final circuit must satisfy the device's input, output, common-mode, stability, and load requirements described in the manufacturer datasheet. The 8-TSSOP package offers a smaller board area than an SOIC-8 package, but its lead pitch requires careful component placement and assembly planning.
Typical application areas include transducer signal conditioning, low-frequency closed-loop control, analog sensor interfaces, active filters, and general buffer or gain stages. In a sensor interface, the op amp may amplify a small differential signal before downstream conversion. In a filter, its gain and bandwidth behavior participate in setting the transfer function. In a feedback-control circuit, the dual package can support related signal paths without requiring two separate single-channel packages.
Designers should follow the manufacturer datasheet for the complete electrical limits, pin assignments, common-mode range, output-swing limits, input-bias-current behavior, noise characteristics, and recommended operating conditions. Decoupling and layout decisions should be based on the intended circuit topology, especially when the amplifier drives capacitive loads or operates close to supply rails. PCB signal-return paths should remain short and preserve a low-impedance ground connection.
This page combines the exact package and headline device information with practical selection guidance, verified source links, an explicit data-completeness assessment, and engineering-focused application notes. It also distinguishes pin-compatible alternatives from broader functional equivalents so engineers can make a replacement decision without assuming that similar amplifier performance guarantees footprint, bias, stability, or operating-range compatibility.

Ứng dụng tiêu biểu
LM358PWRG3 phù hợp cho 6 Áp dụngs: Sensor Signal Conditioning, Active Filtering, Low-Frequency Feedback Control, Transducer Interface, Power-Supply Monitoring, General Analog Buffering.
Sensor Signal Conditioning
The LM358PWRG3 can condition low-frequency sensor signals using one of its two general-purpose amplifier channels while the second channel supports a related feedback, buffer, or filtering function. Its 700 kHz gain-bandwidth product provides useful closed-loop bandwidth for many slow sensor signals, and the 8-TSSOP package helps reduce board area. The design must verify the sensor's output range against the amplifier's input limits, common-mode range, and output-swing requirements. Supply decoupling, grounding, and feedback stability should follow the manufacturer datasheet.
Được đề xuất
Active Filtering
The LM358PWRG3 is appropriate for first- and second-order active-filter stages operating at low frequencies when its 700 kHz gain-bandwidth product provides adequate closed-loop bandwidth and loop gain. Two channels can implement a state-variable filter, buffer an RC network, or form separate filtering stages. Component tolerances and amplifier gain-bandwidth behavior directly affect the intended response, so verify stability and frequency response in simulation. The 16 V maximum supply rating must also be reconciled with the required signal swing and internal operating range.
Được đề xuất
Low-Frequency Feedback Control
The two amplifier channels in LM358PWRG3 can support a compact low-frequency feedback-control circuit, such as an analog error amplifier paired with a monitoring or drive buffer. The 700 kHz gain-bandwidth product is generally relevant to slow control loops rather than high-bandwidth servo systems. Validate the closed-loop response against the amplifier open-loop behavior, load, output-swing capability, and phase margin. Thermal and supply checks are also necessary if the amplifier drives a load that changes significantly with temperature.
Được đề xuất
Transducer Interface
A resistive or bridge-based transducer can use an LM358PWRG3 channel to amplify a small differential voltage while the other channel buffers a reference or supports output conditioning. The dual 8-TSSOP implementation reduces the number of amplifier packages on a compact analog board. Because the LM358PWRG3 is a general-purpose device, the engineer should verify input offset voltage, input bias current, common-mode range, and output swing for the actual transducer output. A sensor-specific amplifier may be preferable when those parameters dominate the design.
Được đề xuất
Power-Supply Monitoring
LM358PWRG3 can monitor a supply-related voltage and buffer or amplify the result for comparison or control circuitry. One channel may monitor a divided supply node, while the other channel buffers a reference-derived signal or drives an analog threshold. The device's 16 V maximum supply rating is a primary design boundary, and the monitored node must remain within the applicable input and common-mode limits. For production power systems, verify the amplifier's operating-temperature grade and behavior at the minimum available supply voltage.
Được đề xuất
General Analog Buffering
The LM358PWRG3 can implement voltage buffers, unity-gain followers, and basic gain stages where two channels reduce package count and PCB congestion. Its 700 kHz gain-bandwidth product suits low-frequency buffering, while the 8-TSSOP footprint supports compact surface-mount layouts. Buffer performance must be checked for capacitive loading, output swing, input common-mode range, and stability. The two channels should also be considered for different voltage-domain requirements only after confirming that each channel's common-mode and output limits are acceptable.

Ghi chú thiết kế
Place the LM358PWRG3 close to the signals it handles and maintain a low-impedance ground reference. The 8-TSSOP lead pitch requires assembly-capable pad spacing and careful orientation; pin 1 identification should follow the package marking and manufacturer pinout. Keep high-current return paths away from sensitive input and feedback traces, and route each feedback connection directly to its associated output and input pins.
Use the 16 V maximum supply rating as an absolute design boundary rather than a recommended operating target. Confirm the actual supply range, input common-mode range, and output-swing limits from the manufacturer datasheet. Add local supply bypassing with the capacitance and placement recommended for the operating frequency, and verify that startup or load transients cannot push the device outside its stated supply limits.
Do not assume that every LM358-family amplifier is a drop-in substitute solely because it is described as equivalent. Confirm package dimensions, pin numbering, supply range, bias current, common-mode limits, output swing, temperature grade, and stability for the exact suffix. The 700 kHz gain-bandwidth product also does not guarantee the same usable bandwidth in every feedback topology because noise gain and loading affect the closed-loop response.
Avoid long, high-impedance input and feedback traces, particularly when the source resistance is high. Keep sensitive nodes physically separated from clocked or switching signals and route them over a continuous ground plane where practical. If driving a capacitive load, consult the manufacturer guidance for isolation or compensation because excessive capacitive loading can reduce stability and cause oscillation.
