REF3330AIDCKTG4 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a star-ground connection, with the REF3330AIDCKTG4 placed close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is referencing. Additionally, use a low-impedance power supply, and keep the device away from high-current or high-frequency signals.
  • Use a low-ESR capacitor (e.g., 10 μF) between the VCC and GND pins, and a smaller capacitor (e.g., 100 nF) between the VCC and BYPASS pins. This helps to filter out noise and ensure a stable voltage supply.
  • The REF3330AIDCKTG4 has a typical start-up time of 10 ms. Ensure that your system's power-on sequence allows for this start-up time before using the voltage reference output.
  • The REF3330AIDCKTG4 has built-in protection against input voltage transients and brownout conditions. It can withstand input voltage drops to 1.5 V without affecting the output voltage reference. However, it's still recommended to use a voltage supervisor or reset circuit to ensure a clean power-on sequence.
  • The REF3330AIDCKTG4 has a typical temperature coefficient of 2 ppm/°C. This means that the output voltage reference will change by approximately 2 ppm (parts per million) for every 1°C change in temperature. This can be important to consider in high-precision applications.
