ADS7822E/2K5 datasheet by Texas Instruments

ADS7822E/2K5 Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the ADS7822E/2K5?
  The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly.
• How do I ensure accurate conversions with the ADS7822E/2K5?
  To ensure accurate conversions, make sure to follow the recommended analog input signal conditioning, use a stable reference voltage, and minimize noise on the analog input lines.
• What is the maximum sampling rate of the ADS7822E/2K5?
  The maximum sampling rate of the ADS7822E/2K5 is 200 kHz, but this can be affected by the clock frequency, conversion mode, and other factors. Refer to the datasheet for more information.
• Can I use the ADS7822E/2K5 with a 3.3V supply voltage?
  Yes, the ADS7822E/2K5 can operate with a 3.3V supply voltage, but the analog input range will be limited to 0-2.5V. Consult the datasheet for more information on operating the device at 3.3V.
• How do I handle the digital output data from the ADS7822E/2K5?
  The ADS7822E/2K5 outputs 12-bit digital data in a serial format. You can use a microcontroller or FPGA to receive and process the data. Make sure to follow the recommended data formatting and timing requirements.
