REF5050AIDGKT datasheet by Texas Instruments

REF5050AIDGKT Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the REF5050AIDGKT to minimize noise and ensure optimal performance?
  It is recommended to place the REF5050AIDGKT close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is supplying, and to use a solid ground plane and decoupling capacitors to minimize noise and ensure optimal performance.
• How do I ensure the REF5050AIDGKT is properly bypassed and decoupled to prevent noise and oscillations?
  To ensure proper bypassing and decoupling, use a 10uF to 22uF ceramic capacitor between the VIN pin and GND, and a 100nF to 1uF ceramic capacitor between the VOUT pin and GND, placed as close to the REF5050AIDGKT as possible.
• What is the maximum capacitive load that the REF5050AIDGKT can drive?
  The REF5050AIDGKT can drive up to 10nF of capacitive load, but it is recommended to limit the capacitive load to 1nF to 4.7nF for optimal performance and stability.
• How do I handle the power-up and power-down sequencing of the REF5050AIDGKT to prevent damage or incorrect operation?
  It is recommended to power up the REF5050AIDGKT after the input voltage (VIN) has reached a stable level, and to power down the REF5050AIDGKT before the input voltage drops below the minimum operating voltage.
• What is the thermal derating of the REF5050AIDGKT, and how does it affect the maximum operating temperature?
  The REF5050AIDGKT has a thermal derating of 2.5mW/°C above 25°C, which means the maximum operating temperature is reduced by 2.5°C for every 1mW of power dissipation above 25°C.
