TL1963ADCQR Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TL1963ADCQR to minimize noise and ensure optimal performance?
  It is recommended to follow a star-grounding scheme, keep the analog and digital grounds separate, and place the device close to the analog signal sources. Additionally, ensure that the device is placed away from high-current carrying traces and noisy components.
• How do I ensure the TL1963ADCQR is properly calibrated for accurate ADC conversions?
  The TL1963ADCQR has an internal calibration circuit that is enabled by default. However, it is recommended to perform an external calibration using an external voltage reference and a calibration resistor to ensure accurate ADC conversions.
• What is the maximum clock frequency that can be used with the TL1963ADCQR?
  The TL1963ADCQR can operate with clock frequencies up to 20 MHz. However, it is recommended to use a clock frequency of 10 MHz or less to ensure optimal performance and minimize jitter.
• How do I handle overvoltage conditions on the analog input pins of the TL1963ADCQR?
  The TL1963ADCQR has internal overvoltage protection on the analog input pins. However, it is recommended to use external protection circuitry, such as voltage-limiting resistors and diodes, to prevent damage from overvoltage conditions.
• What is the recommended power-up sequence for the TL1963ADCQR?
  The recommended power-up sequence is to first apply the analog power supply (AVDD), followed by the digital power supply (DVDD), and then the clock signal. This ensures that the device powers up correctly and minimizes the risk of latch-up.
