ADS8345N Frequently Asked Questions (FAQs)

  • The recommended power-on 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 interference, keep the analog and digital grounds separate, use a solid ground plane, and keep the analog input signals 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 ADS8345N is 100 kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and other factors.
  • The ADS8345N outputs 16-bit data in two's complement format. The most significant bit (MSB) is the sign bit, and the remaining 15 bits represent the magnitude of the signal. You can use a microcontroller or FPGA to process the output data.
  • The REFOUT pin provides a buffered reference voltage output that can be used as a reference for other devices in the system. This can help to reduce noise and improve overall system performance.
