ADS8344EB/2K5 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the analog input signal. This ensures proper operation and prevents damage to the device.
  • To minimize noise and ensure accurate conversions, keep the analog input traces short and away from digital traces, use a solid ground plane, and decouple the power supplies with capacitors. Additionally, use a low-ESR capacitor for the AVCC pin.
  • The maximum sampling rate of the ADS8344EB/2K5 is 100 kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and other factors.
  • The ADS8344EB/2K5 outputs data in binary format. The most significant bit (MSB) is the sign bit, and the remaining bits represent the magnitude of the converted value.
  • The REFOUT pin provides a buffered reference voltage output that can be used as a reference for other devices in the system. Connect a 0.1 μF capacitor from REFOUT to GND to filter the reference voltage.
