Typical Applications
LM358DR is suitable for 6 applications: Sensor Signal Conditioning, Active Filters, Battery-Powered Devices, Industrial Control, Audio Preamplifiers, Power Supply Control.
Sensor Signal Conditioning
The LM358DR is ideal for amplifying small sensor signals, such as thermocouples or photodiodes, due to its low input bias current and wide supply range. It can operate from a single 5V supply, making it suitable for portable instrumentation. The dual channels allow simultaneous conditioning of two sensors, and its 700 kHz bandwidth is sufficient for most sensor frequencies. The output can drive an ADC directly, simplifying the interface.
Recommended
Active Filters
The LM358DR can be used in active filter circuits, such as low-pass or high-pass filters, for audio and control applications. Its 700 kHz gain bandwidth product allows filter cutoff frequencies up to a few hundred kHz. The dual op-amp configuration enables second-order filters with a single IC. The wide supply voltage range supports both 5V and ±15V systems. For higher-order filters, multiple LM358DRs can be cascaded.
Recommended
Battery-Powered Devices
With a quiescent current of only 500 µA per amplifier, the LM358DR is well-suited for battery-powered devices like portable meters and wireless sensors. It can operate down to 3V, allowing direct connection to lithium-ion batteries. The low power consumption extends battery life, while the dual channels provide flexibility for multiple functions. The SOIC-8 package is compact, saving board space in handheld designs.
Recommended
Industrial Control
The LM358DR is used in industrial control systems for signal conditioning, current sensing, and motor control loops. Its wide supply range (up to 32V) allows direct operation from 24V industrial buses. The robust design includes short-circuit protection and internal frequency compensation. The dual channels can handle both feedback and control signals. Its 0°C to 70°C temperature range covers most industrial environments.
Recommended
Audio Preamplifiers
The LM358DR can serve as a simple audio preamplifier for microphone or line-level signals. Its 700 kHz bandwidth is adequate for voice and basic audio, though not for high-fidelity music. The low distortion and wide output swing make it suitable for headphone drivers. The dual channels enable stereo preamplification. For better audio quality, consider the NE5532, but the LM358DR offers a cost-effective solution for basic audio.
Recommended
Power Supply Control
The LM358DR is commonly used in power supply feedback loops, such as in linear regulators and switching converters. Its high gain and wide bandwidth allow precise voltage regulation. The dual channels can implement both voltage and current control. The wide supply range matches the input voltages of many power supplies. The low offset voltage ensures accurate regulation.

Key Differentiators
- Industry-standard dual op-amp with proven reliability (vs LM358MX)
- Wide supply voltage range (3V to 32V) (vs LM2904DR)
- Low quiescent current (500 µA per amp) (vs NE5532)
Design Notes
For single-supply operation, connect pin 4 (V-) to ground and pin 8 (V+) to the positive supply. Bypass each supply pin with a 0.1 µF ceramic capacitor placed as close to the IC as possible. For dual-supply operation, use ±15V supplies and bypass both rails. The LM358DR can operate from a single 3V supply, but ensure the output swing is within the common-mode range.
Keep the feedback loop short and direct to minimize parasitic capacitance. For high-impedance inputs, guard traces to reduce leakage currents. Use a ground plane to reduce noise. The SOIC-8 package has a thermal resistance of approximately 158°C/W, so for high-power applications, provide adequate copper area for heat dissipation.
The LM358DR output cannot swing fully to the supply rails; it typically swings to within 1.5V of the positive rail and 20mV of the negative rail. Do not exceed the absolute maximum supply voltage of 32V. Also, the input common-mode range includes ground, but not the positive rail. For accurate DC measurements, use precision resistors in the feedback network.
Compliance Information
