ADS8548SRGCT Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The datasheet provides a recommended layout and routing guide, but it's also recommended to consult with a PCB design expert to ensure optimal performance.
  • To optimize performance in a noisy environment, ensure proper grounding, use a low-pass filter on the analog input, and consider using a shielded enclosure. Additionally, use a high-quality power supply and decouple the power pins with capacitors. It's also recommended to use a common-mode filter on the analog input.
  • The maximum sampling rate of the ADS8548SRGCT is 500 kSPS. However, the actual achievable sampling rate may be limited by the system's clock frequency, analog input bandwidth, and other system-level factors.
  • The ADS8548SRGCT has an internal calibration circuit that can be enabled through the CAL pin. The calibration process involves shorting the CAL pin to the analog input, and then applying a known voltage to the input. The device will then adjust its internal gain and offset to optimize performance.
  • The power consumption of the ADS8548SRGCT varies depending on the operating mode and sampling rate. In normal operation, the device consumes around 35 mW. In power-down mode, the device consumes around 10 μW.
