LM358PWRG4 datasheet by Texas Instruments

LM358PWRG4 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM358PWRG4?
  The maximum power dissipation of the LM358PWRG4 is 670mW, which is calculated based on the package thermal resistance and the maximum junction temperature.
• Can I use the LM358PWRG4 as a comparator?
  While the LM358PWRG4 is an op-amp, it can be used as a comparator in a pinch. However, it's not the best choice due to its limited bandwidth and slew rate. A dedicated comparator like the LM339 would be a better choice.
• How do I ensure stability when using the LM358PWRG4 in a feedback loop?
  To ensure stability, make sure to follow proper PCB layout practices, use a low-ESR capacitor for decoupling, and consider adding a compensation capacitor in the feedback loop if necessary. Also, ensure that the gain and phase margins are sufficient to prevent oscillations.
• What is the input impedance of the LM358PWRG4?
  The input impedance of the LM358PWRG4 is typically around 2MΩ, but it can vary depending on the specific application and operating conditions.
• Can I use the LM358PWRG4 in a single-supply configuration?
  Yes, the LM358PWRG4 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 external resistors to set the output voltage to the desired level.
