ADCS7478AIMFE/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments provides a layout and routing guide in the application note 'AN-1515: A 14-Bit, 125 MSPS ADC Layout and Routing Guidelines' which provides detailed recommendations for optimal performance.
  • The ADCS7478AIMFE/NOPB has an internal calibration feature that can be used to improve accuracy. Refer to the datasheet section 'Calibration' for details on how to perform calibration. Additionally, Texas Instruments provides an application note 'AN-1516: Calibration and Testing of the ADCS7478' that provides more information on calibration and testing.
  • The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD). This ensures that the analog circuitry is powered up before the digital circuitry. Refer to the datasheet section 'Power-Up Sequence' for more information.
  • The clock input to the ADCS7478AIMFE/NOPB should be a low-jitter, high-frequency clock signal. Texas Instruments recommends using a clock signal with a frequency of at least 10 times the sampling frequency. Additionally, the clock signal should be routed close to the ADC to minimize noise and jitter. Refer to the datasheet section 'Clock Input' for more information.
  • The output data bus of the ADCS7478AIMFE/NOPB should be driven using a low-impedance driver, such as a buffer or a logic gate, to ensure proper signal integrity. Texas Instruments recommends using a driver with an output impedance of less than 50 ohms. Refer to the datasheet section 'Digital Output' for more information.
