ADS8344N/1K Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the analog input signal. This sequence helps prevent latch-up and ensures proper device operation.
  • 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 0.1uF and 10uF capacitors. Also, consider using a separate analog ground plane and connecting it to the digital ground plane at a single point.
  • The maximum sampling rate of the ADS8344N/1K is 100kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and other factors. Consult the datasheet and application notes for more information.
  • The ADS8344N/1K outputs data in straight binary format. The most significant bit (MSB) is the sign bit, and the remaining bits represent the magnitude of the conversion result.
  • The REFOUT pin provides a buffered reference voltage output that can be used as a reference for other devices in the system. Connect a 0.1uF capacitor from REFOUT to GND to filter the reference voltage and reduce noise.
