ADS8321E/250 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, ensure that the analog input signal is properly terminated and filtered to prevent aliasing.
  • The maximum sampling rate of the ADS8321E/250 is 250 kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and other system-level factors.
  • The ADS8321E/250 outputs 16-bit data in a binary two's complement format. The most significant bit (MSB) is the sign bit, and the remaining 15 bits represent the magnitude of the input signal. You can use a microcontroller or FPGA to process and convert the output data as needed.
  • The typical power consumption of the ADS8321E/250 is around 15 mW at a supply voltage of 5V and a sampling rate of 250 kSPS. However, the actual power consumption may vary depending on the system's clock frequency, analog input signal, and other factors.
