LM358DGKRG4 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM358DGKRG4?
  The maximum power dissipation of the LM358DGKRG4 is 670mW, which is calculated based on the maximum junction temperature (150°C) and the thermal resistance from junction to ambient (125°C/W).
• Can I use the LM358DGKRG4 as a comparator?
  While the LM358DGKRG4 can be used as a comparator, it's not the best choice due to its limited slew rate (0.5V/μs) and bandwidth (1MHz). TI recommends using a dedicated comparator like the LM339 or LM2903 for comparator applications.
• How do I ensure stability when using the LM358DGKRG4 in a feedback loop?
  To ensure stability, make sure to follow proper PCB layout practices, use a bypass capacitor (e.g., 10nF) between the supply pins, and avoid using long wires or traces that can introduce parasitic inductance. Additionally, consider adding a compensation capacitor (e.g., 10pF) between the output and the inverting input.
• What is the input impedance of the LM358DGKRG4?
  The input impedance of the LM358DGKRG4 is typically around 2MΩ, but it can vary depending on the specific application and operating conditions. This is relatively low compared to other op-amps, so it's essential to consider the input impedance when designing your circuit.
• Can I use the LM358DGKRG4 in a single-supply configuration?
  Yes, the LM358DGKRG4 can be used in a single-supply configuration, but you'll need to ensure that the input common-mode voltage range is within the specified limits (typically 0V to VCC-1.5V). You may also need to add a voltage divider or level shifter to adjust the input signal to the correct voltage range.
