LM358DR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM358DR?
  The maximum power dissipation of the LM358DR is 670mW, which is calculated based on the package thermal resistance and the maximum junction temperature.
• Can I use the LM358DR as a comparator?
  While the LM358DR can be used as a comparator, it's not the best choice due to its relatively slow slew rate and limited bandwidth. A dedicated comparator like the LM339 or LM2901 would be a better option.
• How do I ensure stability when using the LM358DR in a feedback loop?
  To ensure stability, make sure to add a compensation capacitor (typically 10-100pF) between the output and the inverting input, and adjust the gain and bandwidth of the amplifier to prevent oscillations.
• What is the input impedance of the LM358DR?
  The input impedance of the LM358DR is typically around 2MΩ, but it can vary depending on the specific application and operating conditions.
• Can I use the LM358DR in a single-supply configuration?
  Yes, the LM358DR can be used in a single-supply configuration, but you'll need to ensure that the input signals are referenced to the midpoint of the supply voltage, and that the output voltage swing is limited to avoid clipping.
