REF3425TIDBVR Frequently Asked Questions (FAQs)

  • The typical output noise voltage of the REF3425 is around 10 μVpp (peak-to-peak) from 0.1 Hz to 10 Hz, and 2 μVrms (root mean square) from 10 Hz to 100 kHz.
  • To ensure proper operation, power the REF3425 with a low-noise, well-regulated supply, and decouple the input pins (VIN and GND) with a 10 μF ceramic capacitor and a 100 nF ceramic capacitor in parallel, placed as close to the device as possible.
  • The recommended output capacitor value for the REF3425 is 10 μF to 22 μF, with a low equivalent series resistance (ESR) to ensure stability and minimize output noise.
  • Yes, the REF3425 is suitable for use as a voltage reference for an ADC, thanks to its low noise, high accuracy, and low temperature coefficient. However, ensure the REF3425 is properly decoupled and the output is buffered if necessary to prevent noise coupling into the ADC.
  • During power-up, the REF3425 output voltage ramps up slowly to prevent overshoots and ensure a stable output. During power-down, the output voltage decays slowly to prevent voltage spikes. This behavior helps prevent damage to downstream circuits.
