LM318H/NOPB Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM318H/NOPB?
  The maximum power dissipation of the LM318H/NOPB is 1.4W, which is dependent on the ambient temperature and the thermal resistance of the package.
• Can I use the LM318H/NOPB as a comparator?
  While the LM318H/NOPB 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 (1MHz). A dedicated comparator like the LM339 or LM2901 would be a better option.
• How do I ensure stability when using the LM318H/NOPB in a feedback loop?
  To ensure stability, make sure to follow proper compensation techniques, such as adding a capacitor in parallel with the feedback resistor to reduce the gain at high frequencies. Additionally, ensure that the feedback loop has a sufficient phase margin (>45°) to prevent oscillations.
• What is the input impedance of the LM318H/NOPB?
  The input impedance of the LM318H/NOPB is typically around 2MΩ, which is relatively high. However, this can vary depending on the specific application and operating conditions.
• Can I use the LM318H/NOPB in a single-supply configuration?
  Yes, the LM318H/NOPB can be used in a single-supply configuration, but it's essential to ensure that the input common-mode voltage range is within the specified limits (typically 2V to VCC-2V). Additionally, the output voltage swing may be reduced in single-supply operation.
