LM148J/PB Frequently Asked Questions (FAQs)

  • The maximum power supply voltage for the LM148J/PB is ±18V.
  • Yes, the LM148J/PB can be used in a single-supply configuration, but the input common-mode voltage range is limited to VCC-2V to VCC+2V.
  • The input impedance of the LM148J/PB is typically around 2MΩ, but it can vary depending on the specific application and operating conditions.
  • While the LM148J/PB can be used as a comparator, it's not the best choice due to its relatively slow slew rate and limited bandwidth. A dedicated comparator like the LM339 would be a better option.
  • To reduce noise and oscillations, ensure proper PCB layout, use decoupling capacitors, and consider adding a noise-reducing capacitor (e.g., 10nF) between the output and the negative supply rail.
