ADS7947SRTET Frequently Asked Questions (FAQs)

  • The recommended layout and routing for the ADS7947SRTET involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the analog input traces. Additionally, it is recommended to use a 4-layer PCB with a dedicated analog power plane and a dedicated digital power plane.
  • To optimize the performance of the ADS7947SRTET in noisy environments, it is recommended to use a low-pass filter at the analog input, use a shielded cable for the analog input, and use a common-mode choke to reduce electromagnetic interference (EMI). Additionally, it is recommended to use a decoupling capacitor at the power supply pins and to use a low-noise power supply.
  • The maximum sampling rate of the ADS7947SRTET is 1 MSPS (million samples per second). However, the actual sampling rate may be limited by the system clock frequency and the conversion time of the ADC.
  • The ADS7947SRTET does not require calibration. It has an internal calibration circuit that calibrates the ADC during power-up. However, it is recommended to perform a system-level calibration to ensure the accuracy of the measurement system.
  • The power consumption of the ADS7947SRTET depends on the operating mode and the sampling rate. In normal operation, the power consumption is typically around 15 mW. In power-down mode, the power consumption is typically around 1 μW.
