ADS1298IPAG datasheet by Texas Instruments

ADS1298IPAG Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the ADS1298IPAG?
  The ADS1298IPAG requires careful layout and placement to minimize noise and ensure optimal performance. TI recommends placing the device close to the electrodes, using a star-ground configuration, and separating analog and digital grounds.
• How do I optimize the gain settings for my specific application?
  The gain settings for the ADS1298IPAG depend on the specific application and electrode configuration. TI recommends using the device's built-in gain calibration feature and adjusting the gain settings based on the signal amplitude and noise floor.
• What is the best way to filter out noise and artifacts in the signal?
  The ADS1298IPAG has built-in filters, but additional filtering may be necessary to remove noise and artifacts. TI recommends using a combination of digital and analog filtering techniques, such as notch filters and low-pass filters, to remove specific frequency bands.
• How do I ensure electromagnetic compatibility (EMC) with the ADS1298IPAG?
  To ensure EMC, TI recommends using a shielded enclosure, keeping the device away from high-frequency sources, and using a common-mode choke to reduce electromagnetic interference.
• What is the recommended power-up sequence for the ADS1298IPAG?
  The recommended power-up sequence for the ADS1298IPAG is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This ensures proper device initialization and minimizes the risk of latch-up.
