ADS1158IRTCT Frequently Asked Questions (FAQs)

  • The ADS1158 datasheet recommends a 4-layer PCB with a solid ground plane, and placing the device close to the analog signal sources to minimize noise. Additionally, it's recommended to use a separate analog ground plane and to keep digital and analog traces separate.
  • To optimize the ADC's performance, consider the following: choose the correct gain setting, adjust the sampling rate, and select the appropriate input range. Additionally, ensure proper PCB layout, minimize noise, and use a stable reference voltage.
  • The ADS1158 can handle input voltages up to ±VREF (typically 4.096V or 2.048V), but it's recommended to keep the input voltage within ±VREF/2 to ensure accurate conversions.
  • The ADS1158 does not require calibration, as it has an internal calibration circuit that ensures accurate conversions. However, it's recommended to perform a system-level calibration to account for any external component tolerances or PCB layout effects.
  • The ADS1158's performance is affected by temperature, with a typical temperature coefficient of ±1 ppm/°C. Ensure that the device operates within the recommended temperature range (-40°C to 125°C) for optimal performance.
