ADS7843IDBQRQ1 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VREF, and then the clock signal. This ensures proper initialization of the device.
  • The BUSY signal goes high during conversion and remains high until the conversion is complete. The host should wait for BUSY to go low before accessing the data.
  • The maximum frequency of the clock signal is 3.25 MHz. Exceeding this frequency may result in incorrect conversions or device malfunction.
  • The gain of the ADC can be configured using the GAIN pin. A logic high on the GAIN pin sets the gain to 1, while a logic low sets the gain to 2.
  • The CAL pin is used for calibration of the ADC. It should be tied to VREF or VCC/2 depending on the application requirements.
