LM358PWR datasheet by Texas Instruments

LM358PWR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM358PWR?
  The maximum power dissipation of the LM358PWR is 670mW, which is calculated based on the package thermal resistance and the maximum junction temperature.
• Can I use the LM358PWR as a comparator?
  Yes, the LM358PWR can be used as a comparator, but it's not recommended due to its limited bandwidth and slew rate. It's better suited for amplifying small signals.
• How do I ensure stability when using the LM358PWR in a feedback loop?
  To ensure stability, make sure to add a capacitor (typically 10nF to 100nF) between the output and the inverting input to prevent oscillations. Also, ensure the feedback loop has a sufficient phase margin.
• What is the input impedance of the LM358PWR?
  The input impedance of the LM358PWR is typically around 2MΩ, but it can vary depending on the specific application and operating conditions.
• Can I use the LM358PWR in a single-supply configuration?
  Yes, the LM358PWR can be used in a single-supply configuration, but you'll need to ensure the input signal is biased around the midpoint of the supply voltage to maintain a linear output.
