REF3112AIDBZR datasheet by Texas Instruments

REF3112AIDBZR Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the REF3112AIDBZR?
  The REF3112AIDBZR requires careful layout and placement to ensure optimal performance. It is recommended to place the device close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is providing a reference voltage to, and to use a solid ground plane to minimize noise and radiation.
• How do I ensure the REF3112AIDBZR is stable and accurate over temperature?
  To ensure stability and accuracy over temperature, it is recommended to use a bypass capacitor (e.g., 10nF) between the VOUT pin and GND, and to keep the device away from heat sources and high-power components. Additionally, the device should be operated within its specified temperature range (-40°C to 125°C).
• What is the recommended input voltage range for the REF3112AIDBZR?
  The recommended input voltage range for the REF3112AIDBZR is 4.5V to 18V. Operating the device outside of this range may affect its performance and accuracy.
• How do I handle the power-up and power-down sequences for the REF3112AIDBZR?
  It is recommended to power up the REF3112AIDBZR after the input voltage has reached its nominal value, and to power down the device before the input voltage drops below 4.5V. This ensures that the device is properly initialized and avoids any potential latch-up or damage.
• What is the typical start-up time for the REF3112AIDBZR?
  The typical start-up time for the REF3112AIDBZR is around 10ms, but this can vary depending on the input voltage, temperature, and other factors. It is recommended to wait for at least 10ms after power-up before using the reference voltage.
