ADS5463HFG/EM datasheet by Texas Instruments

ADS5463HFG/EM Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the ADS5463HFG/EM?
  The recommended power-up sequence is to apply the analog supply voltage (AVDD) first, followed by the digital supply voltage (DVDD) and then the clock signal. This ensures proper initialization of the device.
• How do I optimize the analog input impedance for the ADS5463HFG/EM?
  To optimize the analog input impedance, use a low-impedance source, such as a buffer amplifier, and ensure that the input signal is properly terminated. Additionally, consider using a differential input configuration to reduce common-mode noise.
• What is the maximum clock frequency that can be used with the ADS5463HFG/EM?
  The maximum clock frequency for the ADS5463HFG/EM is 650 MSPS. However, the actual clock frequency may be limited by the specific application and system requirements.
• How do I handle the output data format of the ADS5463HFG/EM?
  The ADS5463HFG/EM outputs 14-bit data in a binary two's complement format. The output data can be processed using a FIFO or a processor, and may require formatting and scaling depending on the specific application.
• What is the typical power consumption of the ADS5463HFG/EM?
  The typical power consumption of the ADS5463HFG/EM is around 1.2 W at 650 MSPS, with a 1.8 V analog supply voltage and a 1.2 V digital supply voltage. However, actual power consumption may vary depending on the specific application and operating conditions.
