REF3333AIDBZRG4 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a star-grounded layout with a solid ground plane, and placing the REF3333AIDBZRG4 close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is supplying. Additionally, keep the input and output traces short and separate to minimize noise and coupling.
  • To ensure stability and accuracy over temperature, it is recommended to decouple the input pin (VIN) with a 10uF capacitor, and use a low-ESR output capacitor (COUT) of at least 10uF. Additionally, keep the device away from heat sources and ensure good airflow around the device.
  • The REF3333AIDBZRG4 can supply up to 10mA of output current. However, it is recommended to limit the output current to 5mA or less to ensure optimal performance and accuracy.
  • Yes, the REF3333AIDBZRG4 can be used as a reference voltage for multiple devices, but it is recommended to buffer the output voltage with an op-amp or a dedicated buffer IC to prevent loading and ensure accuracy.
  • It is recommended to power up the REF3333AIDBZRG4 after the input voltage (VIN) has reached its nominal value, and to power down the device before the input voltage drops below its minimum specified value. This ensures that the device starts up and shuts down correctly and prevents any potential damage.
