ADS8344EB Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the analog input voltage. This ensures proper device operation and prevents latch-up.
  • To minimize noise and ensure accurate conversions, keep analog and digital traces separate, use a solid ground plane, and place decoupling capacitors close to the device. Also, use a low-impedance analog power supply and avoid running digital traces near the analog input pins.
  • The maximum sampling rate of the ADS8344EB is 100 kSPS. However, the actual achievable sampling rate may be limited by the system's analog bandwidth, noise, and other factors.
  • The ADS8344EB outputs 16-bit data in a binary two's complement format. The most significant bit (MSB) is the sign bit, and the remaining 15 bits represent the magnitude of the converted value.
  • The REF199 is an external voltage reference that provides a stable 2.048V reference voltage to the ADS8344EB. Connect the REF199 between the VREF pin and GND, and decouple it with a 10uF capacitor to ensure a stable reference voltage.
