ADS8344NB 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 internal biasing and prevents latch-up.
  • To minimize noise and interference, keep the analog and digital grounds separate, use a solid ground plane, and keep the analog input traces short and away from digital signals. Also, use a low-pass filter on the analog input to reduce high-frequency noise.
  • The maximum sampling rate of the ADS8344NB is 100 kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and other factors.
  • The ADS8344NB 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 analog input signal.
  • The REF199 is an internal voltage reference that provides a stable 2.5V reference voltage for the ADC. This reference voltage is used to determine the full-scale range of the ADC and ensures accurate conversions.
