LM358ADG4 datasheet by Texas Instruments

LM358ADG4 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM358ADG4?
  The maximum power dissipation of the LM358ADG4 is 670mW, which is calculated based on the maximum junction temperature (150°C) and the thermal resistance (θJA) of the package.
• Can I use the LM358ADG4 as a comparator?
  While the LM358ADG4 can be used as a comparator, it's not the best choice due to its relatively slow slew rate (0.5V/μs) 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 LM358ADG4 in a feedback loop?
  To ensure stability, make sure to add a capacitor (typically 10-100nF) between the output and the inverting input to compensate for the op-amp's internal capacitance. Additionally, ensure the feedback loop has a gain of less than 1 at the frequency of interest.
• What is the input impedance of the LM358ADG4?
  The input impedance of the LM358ADG4 is typically around 2MΩ, but it can vary depending on the specific application and operating conditions.
• Can I use the LM358ADG4 in a single-supply configuration?
  Yes, the LM358ADG4 can be used in a single-supply configuration, but you'll need to ensure the input common-mode voltage is within the specified range (VCC-1.5V to VCC-0.5V). You may also need to add a voltage divider or level shifter to adjust the input voltage.
