REF3040AIDBZR Frequently Asked Questions (FAQs)

  • The typical output voltage tolerance of the REF3040 is ±0.05% (±6 mV) at 25°C.
  • The REF3040 has a built-in power-on reset (POR) circuit that ensures a stable output voltage during power-up and power-down. The output voltage ramps up and down slowly to prevent overshoots and undershoots.
  • The recommended output capacitor value for the REF3040 is 10 μF to 22 μF, depending on the specific application and noise requirements.
  • Yes, the REF3040 is specified to operate from -40°C to 125°C, making it suitable for high-temperature applications. However, the output voltage accuracy and long-term stability may degrade at extreme temperatures.
  • The REF3040 has a high power supply rejection ratio (PSRR) of 90 dB at 1 kHz, which helps to reject input voltage noise and ripple. Additionally, the device has a built-in noise filter to reduce output voltage noise.
