ADS1294CZXGR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended layout and routing guide in the ADS1294CZXGR Evaluation Module User's Guide (SLAU445). It's essential to follow this guide to ensure optimal performance and minimize noise coupling.
  • The gain settings depend on the input signal amplitude and the desired dynamic range. TI provides a gain calculator tool (ADS1294 Gain Calculator) to help determine the optimal gain settings. Additionally, the datasheet provides guidelines for selecting the gain based on the input signal range.
  • The ADS1294CZXGR has a built-in programmable gain amplifier and a low-pass filter. However, additional filtering may be necessary to remove noise and interference. TI recommends using a combination of analog and digital filtering techniques, such as using a notch filter to remove power line noise and a digital filter to remove high-frequency noise.
  • To ensure EMC, follow proper PCB design and layout practices, such as separating analog and digital grounds, using shielding, and minimizing loop areas. Additionally, use EMI filters and ferrite beads to reduce electromagnetic radiation. TI provides guidelines for EMC design in the ADS1294CZXGR datasheet and application notes.
  • The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD). This ensures that the analog circuitry is powered up before the digital circuitry, which helps to prevent latch-up and ensures proper device operation.
