LM248D Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the LM248D is dependent on the package type and ambient temperature. For the SOIC package, the maximum power dissipation is 1.4W at 25°C ambient temperature.
  • To ensure stability in a unity-gain buffer configuration, it's recommended to add a 10-22 ohm resistor in series with the output and a 10-100nF capacitor from the output to ground to prevent oscillations.
  • To minimize noise and EMI, it's recommended to keep the input and output traces short and away from each other, use a ground plane, and decouple the power supply with a 10uF capacitor.
  • While the LM248D can be used as a comparator, it's not recommended due to its relatively slow slew rate and limited bandwidth. A dedicated comparator like the LM339 or LM2901 is a better choice for comparator applications.
  • To protect the LM248D from overvoltage and ESD damage, it's recommended to add a 5-10V zener diode or a transient voltage suppressor (TVS) diode across the power supply lines, and use ESD protection devices such as diodes or resistors on the input lines.
