ADS7823E/2K5 Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures proper device operation and prevents latch-up.
  • To ensure accurate conversions, ensure that the analog input voltage is within the specified range, the reference voltage is stable, and the clock frequency is within the recommended range. Also, ensure proper PCB layout and decoupling to minimize noise and interference.
  • The CAL pin is used for calibration purposes. It allows the user to calibrate the device's internal reference voltage to improve accuracy. The CAL pin should be connected to a capacitor to ground for proper operation.
  • Yes, the ADS7823E/2K5 can be used in a ratiometric configuration, where the reference voltage is derived from the analog input signal. This can be useful in applications where the input signal is proportional to the reference voltage.
  • The BUSY signal indicates when the device is busy with a conversion. The BUSY signal should be monitored to ensure that the device is not accessed during a conversion. The BUSY signal can be used to synchronize the microcontroller with the ADC's conversion process.
