ADS1191IPBS Frequently Asked Questions (FAQs)

  • The ADS1191IPBS is a high-impedance device, so it's essential to keep the analog signal traces short and away from digital signal traces. Place the device close to the electrodes, and use a ground plane to minimize noise. Refer to the TI application note 'ADS1191 Layout and Placement Guidelines' for more information.
  • The ADS1191IPBS has a programmable gain amplifier (PGA). To optimize the gain, start with the default gain setting and adjust based on your signal amplitude. Use the device's internal calibration to ensure accurate gain settings. Refer to the TI application note 'ADS1191 PGA Gain Optimization' for more information.
  • The ADS1191IPBS has a built-in notch filter for 50/60 Hz noise rejection. Additionally, use a low-pass filter (e.g., RC filter) to remove high-frequency noise. Implement a digital filter (e.g., FIR filter) in your microcontroller to further reduce noise and interference.
  • Follow proper PCB design and layout guidelines to minimize electromagnetic radiation. Use shielding, grounding, and filtering to reduce electromagnetic interference (EMI). Ensure that your system meets the relevant EMC standards (e.g., IEC 60601-1-2).
  • Use a low-ESR capacitor (e.g., 10 μF) close to the device's power pins to decouple the power supply. Add a 100 nF capacitor in parallel to filter high-frequency noise. Ensure that the power supply is well-regulated and has a low noise floor.
