LMP91200MTX/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout for the LMP91200MTX/NOPB involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the analog signal sources. Additionally, it's recommended to use a 4-layer PCB with a dedicated analog power plane and a dedicated digital power plane.
  • The gain resistor values for the LMP91200MTX/NOPB depend on the desired gain and the input signal range. A good starting point is to use the gain resistor calculation formula provided in the datasheet, and then adjust the values based on the specific application requirements.
  • The maximum input voltage that the LMP91200MTX/NOPB can handle is ±25V. However, it's recommended to limit the input voltage to ±20V to ensure optimal performance and to prevent damage to the device.
  • To filter out noise and interference, it's recommended to use a low-pass filter or a band-pass filter at the input stage, and to use a shielded cable or a twisted pair cable to connect the sensor to the LMP91200MTX/NOPB. Additionally, using a common-mode filter or a differential filter can help to reduce electromagnetic interference (EMI).
  • The recommended power-up sequence for the LMP91200MTX/NOPB is to first apply the analog power supply (AVDD), followed by the digital power supply (DVDD), and then the input signals. This ensures that the device is properly initialized and configured before the input signals are applied.
