An operational amplifier is an analog signal-conditioning IC that compares two input voltages and amplifies their difference. The LM358 family belongs to the operational-amplifier hierarchy within analog amplifier ICs. Each of the two LM358 amplifier channels can support common-mode input operation near ground, making the device suitable for single-supply systems that measure, buffer, amplify, or control signals referenced to 0 V.
The LM358APWE4 combines a typical slew rate of 0.3 V/us with a 700 kHz gain-bandwidth product. Its typical input-offset voltage is 2 mV, while the documented maximum offset is 5 mV. Typical input-offset current is 2 nA and typical input-bias current is 15 nA. A typical supply-current drain of 0.7 mA supports low-power analog signal chains, although the exact operating-current limit should be checked against the manufacturer datasheet for the selected supply voltage.
Each channel is internally frequency compensated and supports a common-mode input range that includes ground. The 32 V differential input rating defines the maximum voltage permitted between the two input terminals. In practical signal-conditioning circuits, these characteristics make the LM358 suitable for noninverting and inverting amplifiers, voltage followers, cross-coupled instrumentation stages, active filters, comparators, and low-frequency closed-loop control loops.
The LM358APWE4 is particularly appropriate for industrial control, sensor-interface, audio, and embedded measurement systems operating from a single supply. Its ground-referenced common-mode capability simplifies designs that sense low-voltage sensor outputs without a negative supply. The two independent channels can also be used together for differential amplification, active filtering, or a general-purpose analog front end.
Circuit design should preserve adequate output-voltage headroom under load and account for input bias-current error at high source impedance. Decoupling capacitors should be placed close to the supply pins, and sensitive analog traces should remain away from switching nodes. Because the two channels share supply pins, their total supply-current demand and thermal dissipation must be considered together.
This page combines package and electrical characteristics, practical application guidance, design checks, and pin-compatible alternatives. It is intended to help engineers evaluate whether the LM358APWE4 fits a new design or an existing 8-TSSOP analog board before committing to a footprint and supply configuration.

Single-Supply Sensor Signal Conditioning
The LM358APWE4 fits low-voltage sensor front ends because its common-mode input range includes ground and its typical input-bias current is 15 nA. Place one channel in a non-inverting configuration and use the other for filtering or gain stage. The 700 kHz typical gain-bandwidth product supports moderate-bandwidth measurements, while 0.3 V/us typical slew rate helps preserve large-signal behavior. Check the bias-current error against the sensor output impedance, and use the manufacturer datasheet to select gain that preserves adequate phase margin.

Industrial Control and Actuator Interfaces
The LM358APWE4 is useful in industrial control circuits that amplify sensor errors and drive control inputs referenced to a single supply. Its 32 V differential input rating and common-mode operation extending to ground suit many 0-to-5 V and 0-to-12 V control signals. The typical 0.7 mA supply-current drain keeps quiescent demand relatively low. For actuator drivers, however, confirm output-current capability and output-voltage swing; the op amp should normally drive a buffer stage rather than a high-current load directly.
추천
Audio Preamplifier and Buffering
The LM358APWE4 can provide moderate-bandwidth gain and impedance buffering for line-level audio control or auxiliary signal paths. Its 0.3 V/us typical slew rate is adequate for many low-frequency audio functions, while the dual configuration allows independent gain or buffer channels. The 700 kHz bandwidth should not be confused with full audio-bandwidth performance across every gain setting; verify closed-loop stability and distortion with the selected feedback network. Avoid designs requiring rail-to-rail output swing unless those conditions are explicitly confirmed by the datasheet.
추천
Active Filtering and Analog Signal Conditioning
The two internally compensated channels of the LM358APWE4 can implement first- and second-order active filters around low-frequency or audio-band signals. The 700 kHz typical gain-bandwidth product leaves frequency headroom above many practical filter corners, although component tolerances and op-amp limitations determine the achievable response. Use the manufacturer application guidance and spice model to validate gain, phase margin, and output swing. Keep the two channels' grounding and decoupling layout symmetrical when they process related signals.
추천
Embedded Measurement Front Ends
The LM358APWE4 is suitable for embedded systems that need low-cost analog amplification before an ADC, particularly when the measured signal is referenced to ground. A 700 kHz typical gain-bandwidth product supports sensor and control-loop bandwidths well below its unity-gain limit. The typical 2 mV input-offset voltage and 15 nA input-bias current must be included in the overall accuracy calculation. For precision systems, select resistor networks with suitable matching and consider a lower-offset amplifier when the sensor output is very small.
추천
Power-Supply Feedback and Monitoring Circuits
The LM358APWE4 can monitor a power rail, amplify the difference between a feedback node and a reference, and provide an error signal to a controller. Its common-mode range that includes ground supports low-voltage feedback nodes, and the 32 V differential input rating covers applications where the two inputs are separated by a larger voltage. The typical 0.7 mA supply-current drain is useful in low-power monitoring. Ensure the input pair never exceeds the differential rating, and use resistor dividers to protect inputs outside the amplifier's normal common-mode range.

설계 노트
Estimated: using the typical 0.7 mA supply-current drain, the LM358APWE4 power dissipation is approximately PD = VS × 0.7 mA. This is 3.5 mW at 5 V and 8.4 mW at 12 V. Use the datasheet's worst-case supply current for thermal margin, especially when both amplifier channels are active. Add a local bypass capacitor from V+ to V- close to pins 8 and 4 to maintain a low-impedance supply path.
Route the two supply pins directly to the supply and ground planes, placing the bypass capacitor at the device rather than at the power-source connector. Keep feedback resistors and non-inverting inputs away from switching-node copper. Because both channels share the same supply pins, a disturbance from either channel's output can couple through the package; route sensitive amplifier A and amplifier B outputs in opposite directions when practical.
The LM358 is not rail-to-rail at its output, and its input common-mode range should not be assumed to extend to the positive supply. Verify output swing and input common-mode limits against the actual signal and supply voltages in the manufacturer datasheet. Also observe the 32 V differential input limit and use resistor attenuation whenever the differential input could exceed that rating during fault conditions.
For high-impedance sensors, the 15 nA typical input-bias current can create a voltage error equal to the bias current multiplied by the effective source impedance. Add a compensation resistor when practical and keep the input node physically small. At higher closed-loop gains, verify phase margin with the actual resistor and capacitor values because the 700 kHz typical gain-bandwidth product does not guarantee stability for every feedback network.
