ADS8345EB 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 0.1uF and 10uF capacitors. Also, ensure that the analog input signal is properly filtered and buffered before connecting it to the ADS8345EB.
  • The maximum sampling rate of the ADS8345EB is 100kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input signal bandwidth, and other system-level factors.
  • The ADS8345EB 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 output data can be easily converted to two's complement format if required by the system.
  • The recommended clock frequency for the ADS8345EB is between 1MHz and 4MHz. A higher clock frequency can improve conversion accuracy, but it also increases power consumption and noise sensitivity. A lower clock frequency can reduce power consumption but may compromise conversion accuracy.
