ADS1213E datasheet by Texas Instruments

ADS1213E Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the ADS1213E?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the ADS1213E close to the analog input sources to minimize noise. Additionally, decoupling capacitors should be placed as close as possible to the device's power pins.
• How do I optimize the ADC's performance for my specific application?
  Optimizing the ADC's performance requires careful consideration of the input signal, clock frequency, and gain settings. TI provides an ADC Performance Calculator tool to help engineers optimize the ADS1213E's performance for their specific application.
• What is the effect of temperature on the ADS1213E's accuracy and performance?
  The ADS1213E's accuracy and performance can be affected by temperature. TI provides temperature coefficients for the device's offset and gain errors, which can be used to correct for temperature-related errors. Additionally, the device's internal temperature sensor can be used to monitor temperature and adjust the ADC's performance accordingly.
• How do I handle EMI and RFI interference when using the ADS1213E?
  To minimize EMI and RFI interference, TI recommends using a shielded enclosure, keeping the analog input signals away from digital signals, and using a common-mode filter or ferrite bead on the analog input lines. Additionally, the ADS1213E's internal digital filter can be used to reject high-frequency noise.
• What is the recommended power-up sequence for the ADS1213E?
  TI recommends powering up the ADS1213E in the following sequence: VDD, AVDD, and then DVDD. This sequence helps to ensure that the device's internal voltage regulators are properly initialized and that the ADC is powered up correctly.
