ADS1191IPBSR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the ADS1191IPBSR close to the analog signal sources to minimize noise. Additionally, it's recommended to keep the analog and digital grounds separate and connect them at a single point.
  • To optimize performance in a noisy environment, use a low-pass filter at the input, keep the analog signal paths short, and use shielding or guarding to reduce electromagnetic interference (EMI). Additionally, consider using a common-mode choke or a ferrite bead to filter out high-frequency noise.
  • The maximum input voltage range for the ADS1191IPBSR is ±6.144V, but it's recommended to keep the input voltage within ±5V to ensure optimal performance and prevent damage to the device.
  • Calibration involves adjusting the offset and gain of the ADC to match the specific application requirements. Texas Instruments provides a calibration procedure in the datasheet, which involves applying a known input voltage and adjusting the offset and gain registers accordingly.
  • The power consumption of the ADS1191IPBSR is typically around 13.5mW at 2.5V and 10ksps. To reduce power consumption, consider using the device's power-down mode, reducing the sampling rate, or using a lower supply voltage.
