ADS7841EB datasheet by Texas Instruments

ADS7841EB Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the ADS7841EB?
  The recommended power-up sequence is to apply VCC first, followed by VREF, and then the analog input signal. This ensures proper operation and prevents damage to the device.
• How do I optimize the analog input signal range for the ADS7841EB?
  The ADS7841EB has a fixed gain of 1, so the analog input signal range should be optimized to match the full-scale range of the ADC (0 to VREF). Use an external amplifier or attenuator if necessary to adjust the signal level.
• What is the purpose of the CAL pin on the ADS7841EB?
  The CAL pin is used for calibration purposes. It allows the user to calibrate the ADC's offset and gain errors. Connecting CAL to VREF or GND sets the calibration mode, and the device adjusts its internal calibration registers accordingly.
• How do I handle the EOC (End of Conversion) signal in my design?
  The EOC signal is an active-low output that indicates the end of a conversion cycle. It can be used to trigger the next conversion or to synchronize with other system components. Ensure that your design properly handles the EOC signal to avoid data loss or corruption.
• What is the maximum sampling rate of the ADS7841EB?
  The maximum sampling rate of the ADS7841EB is 200 kHz. However, the actual sampling rate may be limited by the system's clock frequency, conversion time, and other factors. Consult the datasheet and application notes for more information.
