REF02AUG4 Frequently Asked Questions (FAQs)

  • The REF02AUG4 should be placed close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is supplying, and the output capacitor should be placed as close as possible to the REF02AUG4. The input and output pins should be routed away from noisy digital signals and power supply lines. A solid ground plane and a low-impedance power supply are also recommended.
  • To ensure stability, the REF02AUG4 requires a minimum output capacitance of 10uF, and the output capacitor should be a low-ESR type. The device should also be decoupled from the power supply with a 0.1uF capacitor. Additionally, the PCB layout should be designed to minimize parasitic inductance and capacitance.
  • The maximum allowed voltage drop between the input and output of the REF02AUG4 is 200mV. Exceeding this voltage drop can cause the device to malfunction or become unstable.
  • Yes, the REF02AUG4 can be used as a voltage reference for multiple ADCs or DACs, but the total output current should not exceed the maximum rated output current of 10mA. Additionally, the output impedance of the REF02AUG4 should be considered when designing the system, as it can affect the accuracy of the voltage reference.
  • The REF02AUG4 has a built-in power-on reset circuit that ensures the output is in a high-impedance state during power-up and power-down sequences. The device also has a soft-start feature that limits the inrush current during power-up. However, the power-up and power-down sequences should be designed to ensure that the input voltage to the REF02AUG4 is stable and within the recommended operating range.
