ADS7822EB/2K5 Frequently Asked Questions (FAQs)

  • 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.
  • The ADS7822 outputs data in a 16-bit, 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.
  • The REFOUT pin provides a buffered reference voltage output that can be used as a reference for other devices in the system. It is internally connected to the internal reference voltage generator.
  • Yes, the ADS7822 can be used with an external reference voltage. The REFIN pin can be connected to an external reference voltage source, and the internal reference voltage generator can be disabled by connecting the REFIN pin to a voltage between 2.5V and 5.5V.
  • The maximum sampling rate of the ADS7822 is 200 kHz. However, the actual sampling rate may be limited by the system's clock frequency and the conversion time of the ADC.
