ADM238LARZ Frequently Asked Questions (FAQs)

  • A good layout and routing practice is to keep the analog and digital grounds separate, use a solid ground plane, and keep the signal traces short and away from noise sources. Also, use a low-ESR capacitor for the VCC pin and a 0.1uF capacitor for the AVCC pin.
  • The ADM238LARZ requires a single 5V power supply. Ensure that the power supply is clean and regulated. Power sequencing is not critical, but it's recommended to power up the VCC pin before the AVCC pin.
  • The ADM238LARZ can achieve a maximum data transfer rate of 230.4 kbps in asynchronous mode and 1 Mbps in synchronous mode.
  • Use the TXRDY and RXRDY pins to monitor the FIFO status. Implement a FIFO management scheme to ensure that data is not overwritten or lost. Use the FIFO interrupts to trigger data transmission and reception.
  • Use a shielded cable for the serial interface, add EMI filters or ferrite beads to the power supply lines, and consider using a ground plane or shielding for the PCB. Also, ensure that the ADM238LARZ is properly decoupled and bypassed.
