ADS8321EB/2K5 datasheet by Texas Instruments

ADS8321EB/2K5 Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the ADS8321EB/2K5?
  The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the analog input signal. This ensures proper device operation and prevents latch-up.
• How do I optimize the layout for the ADS8321EB/2K5 to minimize noise and ensure accurate conversions?
  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.
• What is the maximum sampling rate I can achieve with the ADS8321EB/2K5?
  The maximum sampling rate of the ADS8321EB/2K5 is 100kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and other factors.
• How do I handle the output data from the ADS8321EB/2K5? Is it in binary or two's complement format?
  The ADS8321EB/2K5 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.
• What is the purpose of the CAL pin on the ADS8321EB/2K5, and how do I use it?
  The CAL pin is used for calibration and self-test. It can be used to initiate a self-test sequence, which checks the ADC's internal circuitry and provides a calibration value for optimal performance.
