ADS8548SPM 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. Also, use short and direct traces for the analog inputs and outputs, and avoid crossing digital and analog signals.
  • To minimize noise, use a low-noise power supply, decouple the power pins with 0.1uF and 10uF capacitors, and use a quiet analog ground plane. Also, keep the analog inputs away from digital signals and use shielding if necessary.
  • The ADS8548SPM can achieve a maximum sampling rate of 500 kSPS, but this may vary depending on the specific application and system design. Consult the datasheet and application notes for more information.
  • Calibration involves adjusting the offset and gain of the ADC. Use the internal calibration feature or an external calibration signal to adjust the offset and gain. Consult the datasheet and application notes for specific calibration procedures.
  • The ADS8548SPM has a typical power consumption of 35 mW at 3.3V and 500 kSPS. To reduce power consumption, use the power-down mode, reduce the sampling rate, or use a lower supply voltage. Consult the datasheet for more information.
