ADS1298IPAG Frequently Asked Questions (FAQs)

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
