LM358DG4 datasheet by Texas Instruments

LM358DG4 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM358DG4?
  The maximum power dissipation of the LM358DG4 is 670mW, which is calculated based on the package thermal resistance and the maximum junction temperature.
• Can I use the LM358DG4 as a comparator?
  While the LM358DG4 can be used as a comparator, it's not the best choice due to its relatively slow slew rate (0.5V/us) and limited bandwidth (1.2MHz). A dedicated comparator like the LM339 or LM2901 would be a better option.
• How do I ensure stability when using the LM358DG4 in a feedback loop?
  To ensure stability, make sure to add a capacitor (typically 10-100nF) between the output and the inverting input to prevent oscillations. Additionally, ensure that the feedback loop has a gain of less than 1 at the frequency of interest.
• What is the input impedance of the LM358DG4?
  The input impedance of the LM358DG4 is typically around 2MΩ, but it can vary depending on the specific application and operating conditions.
• Can I use the LM358DG4 in a single-supply configuration?
  Yes, the LM358DG4 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. You may also need to add a voltage divider or level shifter to adjust the input signal levels.
