LMP7708MM/NOPB Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the LMP7708MM/NOPB is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.
  • To ensure stability, it's recommended to use a compensation capacitor (CC) between the output and the inverting input pins. The value of CC depends on the gain and bandwidth requirements of the application. A good starting point is to use a 10pF to 22pF capacitor.
  • To minimize noise and EMI, it's recommended to use a star-ground configuration, keep the input and output traces short and symmetrical, and avoid running digital signals near the analog signals. Additionally, use a ground plane and decouple the power supplies with 0.1uF and 10uF capacitors.
  • While the LMP7708MM/NOPB can be used as a comparator, it's not the most suitable device for this application. The device is optimized for linear operation, and its output stage is not designed for high-speed switching. For comparator applications, a dedicated comparator IC is recommended.
  • The input bias current of the LMP7708MM/NOPB is typically around 1pA. To minimize the effect of input bias current, use a high-impedance input source, and consider using a bias current cancellation technique, such as a current mirror or a super-beta input stage.
