ADS8345NB 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 ensure accurate conversions, it is recommended to keep the analog input traces short and away from digital traces, use a solid ground plane, and decouple the power supplies with capacitors.
  • The maximum sampling rate of the ADS8345NB is 100 kSPS. However, the actual sampling rate may be limited by the system's clock frequency and the conversion time of the ADC.
  • The ADS8345NB outputs 16-bit data in a serial format. The output data is in two's complement format, with the most significant bit (MSB) first. The data is clocked out on the SDO pin during the SCLK falling edge.
  • The REF pin is the reference voltage input for the ADC. It should be connected to a stable voltage reference source, such as a voltage regulator or a bandgap reference. The recommended reference voltage range is 2.5 V to 5.5 V.
