ADC14155CISQ/NOPB datasheet by Texas Instruments

ADC14155CISQ/NOPB Frequently Asked Questions (FAQs)

• What is the recommended input impedance for the ADC14155?
  The recommended input impedance for the ADC14155 is 1 kΩ to 10 kΩ. This ensures proper signal attenuation and prevents signal reflections.
• How do I optimize the ADC's performance for high-frequency signals?
  To optimize the ADC's performance for high-frequency signals, use a low-pass filter at the input to remove high-frequency noise, and ensure the input signal is properly terminated to prevent signal reflections.
• What is the maximum sampling rate I can achieve with the ADC14155?
  The maximum sampling rate of the ADC14155 is 14.4 MSPS (mega-samples per second). However, this rate may vary depending on the specific application and system design.
• How do I handle metastability issues in the ADC14155?
  To handle metastability issues, use a synchronizer or a metastable state detector to detect and correct metastable states. You can also use a clock domain crossing (CDC) circuit to synchronize the clock domains.
• What is the power consumption of the ADC14155?
  The power consumption of the ADC14155 varies depending on the operating mode and sampling rate. In normal operation, the power consumption is typically around 35 mW at 14.4 MSPS. In power-down mode, the power consumption is around 1.5 mW.
