REF3320AIDBZTG4 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a star-ground connection and a symmetrical layout to minimize noise and thermal gradients. Place the device close to the analog-to-digital converter (ADC) and use a solid ground plane to reduce noise coupling.
  • To ensure accurate voltage reference output, use a low-impedance power supply, decouple the input with a 10uF capacitor, and keep the output capacitor (COUT) between 10nF to 100nF. Also, minimize the distance between the REF3320AIDBZTG4 and the ADC input.
  • The thermal resistance (RθJA) of the REF3320AIDBZTG4 package is approximately 45°C/W. This is important to consider when designing the PCB layout and thermal management to ensure the device operates within its specified temperature range.
  • No, the REF3320AIDBZTG4 is a voltage reference device, not a voltage regulator. It is designed to provide a stable voltage reference, but it does not have the capability to regulate voltage or provide a high current output.
  • To ensure proper operation, power up the REF3320AIDBZTG4 after the power supply has stabilized, and power it down before the power supply is turned off. A soft-start circuit can be used to control the power-up sequence and prevent voltage overshoots.
