ADC128S052QCMTX/NOPB datasheet by Texas Instruments

ADC128S052QCMTX/NOPB Frequently Asked Questions (FAQs)

• What is the recommended input impedance for the ADC128S052?
  The recommended input impedance for the ADC128S052 is 1 kΩ to 10 kΩ. This ensures proper signal attenuation and prevents signal reflections.
• How do I handle the ADC's clock signal?
  The ADC128S052 requires a clock signal between 1 MHz to 50 MHz. It's recommended to use a clock signal with low jitter and a stable frequency to ensure accurate conversions.
• What is the purpose of the VREF pin?
  The VREF pin sets the reference voltage for the ADC. It's recommended to connect VREF to a stable voltage source, such as a voltage regulator or a bandgap reference, to ensure accurate conversions.
• How do I handle the ADC's power-on reset (POR) sequence?
  The ADC128S052 has a power-on reset (POR) sequence that ensures the device is properly initialized. It's recommended to follow the POR sequence outlined in the datasheet to ensure proper device operation.
• What is the maximum sampling rate of the ADC128S052?
  The maximum sampling rate of the ADC128S052 is 50 kSPS (kilosamples per second). However, the actual sampling rate may be limited by the system's clock frequency and the ADC's conversion time.
