ADC1175-50CIJM datasheet by Texas Instruments

ADC1175-50CIJM Frequently Asked Questions (FAQs)

• What is the recommended input impedance for the ADC1175?
  The recommended input impedance for the ADC1175 is 1 kΩ to 10 kΩ. This ensures proper signal attenuation and prevents signal reflections.
• How do I handle the ADC1175's high-speed clock output?
  The ADC1175's high-speed clock output requires proper termination and routing to prevent signal degradation and electromagnetic interference (EMI). Use a 50-Ω termination resistor and route the clock signal as a differential pair to minimize signal degradation.
• What is the maximum sampling rate for the ADC1175?
  The maximum sampling rate for the ADC1175 is 50 MSPS (mega-samples per second). However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and digital output data rate.
• How do I optimize the ADC1175's power consumption?
  To optimize the ADC1175's power consumption, use the lowest possible clock frequency, reduce the analog input bandwidth, and use the power-down mode when not in use. Additionally, consider using a lower supply voltage (e.g., 1.8 V instead of 3.3 V) if possible.
• What is the ADC1175's latency, and how does it affect my system design?
  The ADC1175's latency is approximately 10 clock cycles. This means that there is a delay between the analog input signal and the corresponding digital output data. System designers should consider this latency when designing their system's timing and synchronization.
