LM358APE4 - Dual 700kHz Op Amp | Texas Instruments
MPN： LM358APE4 ✓ 啟用中LM358APE4 概覽
An operational amplifier is a voltage-gain device that uses differential input voltage to control an output voltage. Operational amplifiers belong to the analog amplifier hierarchy and are commonly used in voltage followers, noninverting amplifiers, summing circuits, comparators, filters, and current-control loops. A dual package provides two amplifiers in one device, reducing board area and simplifying multi-channel designs.
The LM358APE4 provides a 700 kHz gain-bandwidth product and a 0.3 V/us slew rate. Its supply current is specified at 0.7 mA typical, supporting power-conscious signal-processing designs. The dual push-pull output structure allows the amplifiers to source and sink output current, while the through-hole 8-DIP package supports conventional PCB assembly and socketed prototypes.
This part is identified as a general-purpose amplifier rather than a precision or high-speed device. Its bandwidth is adequate for audio-frequency signal conditioning, sensor interfaces, and low-to-moderate-frequency control loops. Design engineers should account for the finite gain-bandwidth product when selecting feedback resistors and should evaluate output-voltage swing against the selected supply voltage.
Typical uses include dual-channel sensor conditioning, current-to-voltage conversion, active filtering, differential input stages, and general instrumentation. Two independent amplifiers in one package are especially useful when both channels process related or complementary signals, such as an analog sensor pair or an excitation-and-measurement arrangement.
For a new PCB, use the standard 8-DIP footprint and observe the pin assignments shown in the manufacturer datasheet. Place input and feedback components close to their associated amplifier pins to minimize parasitic capacitance and feedback-loop instability. Decoupling capacitors should connect to a low-impedance ground plane with short return paths.
This page combines the LM358APE4 electrical characteristics, practical application guidance, drop-in alternatives, package details, and selection trade-offs into an engineering-focused resource for evaluating the dual operational amplifier in instrumentation, control, and analog signal-conditioning designs.

典型應用
LM358APE4 適用於 6 應用s: Dual-Channel Sensor Conditioning, Active Audio Filters, Industrial Control Loops, Current-to-Voltage Conversion, Data-Acquisition Signal Chains, Power-Supply Monitoring.
Dual-Channel Sensor Conditioning
The LM358APE4 fits dual sensor-conditioning channels because one 8-DIP package contains two general-purpose amplifiers with a 700 kHz gain-bandwidth product and a 0.3 V/us slew rate. The two channels can amplify low-bandwidth sensor outputs, buffer inputs, or form matched noninverting stages without adding a second package. Its 0.7 mA typical supply current supports low-power instrumentation, while the push-pull outputs provide active sourcing and sinking capability. Confirm that both sensor signals remain within the amplifier input common-mode range, keep feedback loops short, and decouple the supply close to pin 8.
推薦
Active Audio Filters
The LM358APE4 can implement first- and second-order active audio filters because its 700 kHz gain-bandwidth product and 0.3 V/us slew rate provide useful margin above typical audio-band control loops. Both amplifiers may form linked filter sections, or one section may provide gain while the other serves as a buffer. The general-purpose architecture is suitable for line-level signal conditioning when full rail-to-rail output is not required. Check the closed-loop gain against the gain-bandwidth limit and confirm that the output swing remains inside the load-dependent limits of the selected supply.
推薦
Industrial Control Loops
The LM358APE4 is suitable for industrial control and feedback functions that do not require the bandwidth of a high-speed amplifier. Its two channels can implement an error amplifier and a signal buffer, a transconductance stage and output driver, or paired feedback paths. The 700 kHz gain-bandwidth product supports many low-bandwidth control loops, and the 0.3 V/us slew rate limits how quickly the output can follow large steps. Compensation components should be calculated with actual load capacitance and feedback-node parasitics in mind, especially when driving long PCB traces or remote plant inputs.
推薦
Current-to-Voltage Conversion
The LM358APE4 can convert the voltage across a sense resistor into a measurable analog level when the signal bandwidth fits its 700 kHz gain-bandwidth product. One channel may perform the conversion while the other amplifies a reference or monitor signal. The dual push-pull output architecture is useful for driving an ADC input or downstream instrumentation stage. Choose resistor values that keep the differential input within the amplifier's common-mode and input ranges, minimize Kelvin routing where accuracy matters, and place the feedback network close to pins 2 and 3 to reduce sensitivity to parasitic capacitance.
推薦
Data-Acquisition Signal Chains
The LM358APE4 can condition multiple low-speed acquisition inputs by providing two independent amplifiers in a single 8-DIP package. Typical uses include differential input conversion, non-inverting gain stages, and anti-alias filter sections feeding an ADC. Its 700 kHz bandwidth and 0.3 V/us slew rate are appropriate for many kilohertz-to-hundreds-of-kilohertz measurement channels, provided the gain and settling requirements are checked. Use short traces, a continuous ground plane, and local supply bypassing to prevent channel-to-channel coupling and ensure stable operation with the ADC's acquisition characteristics.
推薦
Power-Supply Monitoring
The LM358APE4 can monitor a supply rail or scaled feedback node when its input and output ranges support the monitored voltage. One amplifier may buffer a divided supply signal, while the other provides gain or a comparison function for an overvoltage or undervoltage condition. The push-pull output permits direct drive of a logic input or analog measurement stage, subject to current and swing limits. Divide the monitored voltage to keep it inside the common-mode range, include hysteresis for switching applications, and verify the threshold against temperature and supply variation rather than relying only on nominal values.

主要差異化特點
- Two amplifiers in one through-hole package (對比LM358P)
- 650 kHz bandwidth margin over slow control stages (對比LM258AP)
- Direct pin-compatible sourcing path (對比RC4558)
設計說明
Route amplifier inputs, feedback resistors, and compensation components directly beneath their associated pins. Keep pin 4 connected to a low-impedance ground plane and place the supply bypass capacitor between pins 8 and 4 as close as practical. This arrangement minimizes parasitic feedback capacitance, which can turn an otherwise stable gain stage into an oscillator.
Do not assume that single-supply operation permits input or output signals to reach ground rail. Check the input common-mode range and output-swing limits at the intended supply voltage and load. For a mid-supply signal, bias the noninverting input near midrail and ensure the feedback network keeps both inputs within the permitted range.
Use a local supply-decoupling network sized to control impedance over the operating bandwidth rather than relying on long supply traces. Verify the regulator's output capacitance, ESR range, and transient response against the op-amp load. The LM358APE4's 0.7 mA typical supply current is low, but output-current transients and capacitive-load charging can still create local supply disturbance.
A 700 kHz gain-bandwidth product does not provide 700 kHz usable bandwidth at every closed-loop gain. Gain and bandwidth scale together, so high noise gain reduces the achievable signal bandwidth and can increase peaking. Check the closed-loop gain, feedback topology, capacitive load, and expected phase margin before using either channel in a high-Q filter or oscillator.
合規資訊
No explicit RoHS, REACH, lead-free, halogen-free, or conflict-minerals statement is identified for the exact LM358APE4 ordering code. The AEC-Q100 field is not applicable because this is a general-purpose operational amplifier rather than an automotive-qualified device.
