REF5040AIDRG4 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a star-ground configuration, with the REF5040AIDRG4 placed close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is supplying. Additionally, a solid ground plane and short, direct connections to the power supply and load are recommended to minimize noise and ensure optimal performance.
  • The REF5040AIDRG4 has a thermal shutdown feature that turns off the output when the junction temperature exceeds 150°C. To handle thermal considerations, ensure good airflow, use a heat sink if necessary, and consider using a thermally conductive material such as a thermal pad or thermal tape to improve heat dissipation.
  • Texas Instruments recommends a 10-µF ceramic capacitor with an X7R or X5R dielectric as the input capacitor. The input capacitor value and type affect the output noise and stability by filtering the input voltage and reducing the noise sensitivity of the reference voltage. A larger capacitor value can reduce the output noise, but may also increase the startup time.
  • Texas Instruments recommends bypassing the REF5040AIDRG4 with a 0.1-µF ceramic capacitor between the VOUT pin and the GND pin, and a 10-µF ceramic capacitor between the VIN pin and the GND pin. Proper bypassing helps to filter out high-frequency noise and ensure optimal performance.
  • The REF5040AIDRG4 has a maximum output current capability of 10 mA. The output current capability affects the output voltage accuracy, as excessive output current can cause the output voltage to droop or become inaccurate. Ensure that the output current is within the recommended range to maintain optimal output voltage accuracy.
