LM248N Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the LM248N is dependent on the package type and ambient temperature. For the DIP8 package, the maximum power dissipation is 500mW at 25°C. For the SO8 package, it is 320mW at 25°C. Refer to the thermal characteristics section of the datasheet for more information.
  • While the LM248N is an op-amp, it can be used as a comparator in certain applications. However, it is not recommended as it is not optimized for comparator operation. The LM248N has a relatively slow slew rate and may not provide the desired performance in high-speed comparator applications. STMicroelectronics offers dedicated comparator products, such as the LM2903, that are better suited for comparator applications.
  • The input impedance of the LM248N is typically around 2MΩ, but it can vary depending on the specific application and operating conditions. This is not explicitly stated in the datasheet, but it can be inferred from the input bias current and common-mode input impedance specifications.
  • Yes, the LM248N can be used in a single-supply configuration. However, the input common-mode voltage range is limited to within 2V of the positive supply rail, and the output voltage swing is reduced when operating from a single supply. Refer to the application notes and design guidelines in the datasheet for more information on single-supply operation.
  • The noise performance of the LM248N is characterized by its input voltage noise density and input current noise density. The datasheet specifies these parameters as 10nV/√Hz and 0.5pA/√Hz, respectively, at 1kHz. However, the actual noise performance may vary depending on the specific application and operating conditions.
