ADS1192IRSMT datasheet by Texas Instruments

ADS1192IRSMT Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the ADS1192IRSMT?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the ADS1192IRSMT close to the electrodes or sensors to minimize noise and interference. A dedicated analog ground plane is also recommended to separate analog and digital grounds.
• How do I optimize the ADS1192IRSMT's performance for my specific application?
  Optimization involves selecting the right gain, sampling rate, and filter settings based on the application's requirements. TI provides a development kit and software tools to help with this process. Additionally, consulting the application notes and seeking support from TI's engineers can be helpful.
• What is the best way to drive the ADS1192IRSMT's clock input?
  The clock input should be driven by a low-jitter, high-frequency clock source (e.g., a crystal oscillator or a clock generator). A clock frequency of 4.096 MHz or 2.048 MHz is recommended, and the clock signal should be routed close to the ADS1192IRSMT to minimize noise.
• How do I handle the ADS1192IRSMT's power-up and power-down sequences?
  The ADS1192IRSMT requires a specific power-up and power-down sequence to ensure proper operation. The recommended sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock input. During power-down, the sequence should be reversed.
• What are the key considerations for electromagnetic compatibility (EMC) when using the ADS1192IRSMT?
  To ensure EMC, it's essential to follow proper PCB layout and design practices, such as separating analog and digital circuits, using shielding, and minimizing loop areas. Additionally, the ADS1192IRSMT's digital outputs should be properly terminated, and the device should be placed in a shielded enclosure if necessary.
