ADS7828E/250G4 datasheet by Texas Instruments

ADS7828E/250G4 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the ADS7828E/250G4?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures proper device operation and prevents latch-up.
• How do I ensure accurate conversions with the ADS7828E/250G4?
  To ensure accurate conversions, make sure to follow the recommended analog input signal range, use a stable reference voltage, and minimize noise on the analog input lines. Also, ensure the device is operated within the recommended temperature range.
• What is the purpose of the CAL pin on the ADS7828E/250G4?
  The CAL pin is used for calibration purposes. It allows the user to calibrate the device's internal voltage reference, ensuring accurate conversions. The CAL pin should be connected to a 10kΩ resistor to GND for normal operation.
• Can I use the ADS7828E/250G4 in a multiplexed configuration?
  Yes, the ADS7828E/250G4 can be used in a multiplexed configuration. However, it's essential to ensure that the analog input signals are properly multiplexed and that the device is properly configured for multiplexed operation.
• What is the maximum sampling rate of the ADS7828E/250G4?
  The maximum sampling rate of the ADS7828E/250G4 is 250 kSPS (kilosamples per second). However, the actual sampling rate may vary depending on the specific application and system requirements.
