LM358N Frequently Asked Questions (FAQs)

• What is the maximum power supply voltage for the LM358N?
  The maximum power supply voltage for the LM358N is ±18V or 36V total supply voltage.
• Can I use the LM358N as a comparator?
  While the LM358N can be used as a comparator, it's not the best choice due to its limited bandwidth and slew rate. A dedicated comparator like the LM339 or LM2901 is recommended for comparator applications.
• How do I reduce noise and oscillations in my LM358N circuit?
  To reduce noise and oscillations, ensure proper PCB layout, use decoupling capacitors, and add a capacitor (e.g., 10nF) between the output and the inverting input. You can also try adding a resistor (e.g., 1kΩ) in series with the output to reduce oscillations.
• What is the input impedance of the LM358N?
  The input impedance of the LM358N is typically around 2MΩ, but it can vary depending on the specific application and circuit configuration.
• Can I use the LM358N in a single-supply configuration?
  Yes, the LM358N can be used in a single-supply configuration. However, you'll need to ensure that the input signals are referenced to the midpoint of the supply voltage, and you may need to add voltage dividers or level shifters to accommodate the single supply voltage.
