REF5040AIDGKT datasheet by Texas Instruments

REF5040AIDGKT Frequently Asked Questions (FAQs)

• What is the typical output voltage tolerance of the REF5040?
  The typical output voltage tolerance of the REF5040 is ±0.05% (±5 mV) at 25°C.
• How does the REF5040 behave during power-up and power-down?
  The REF5040 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.
• What is the recommended output capacitor value for the REF5040?
  The recommended output capacitor value for the REF5040 is 10 μF to 22 μF, depending on the specific application and noise requirements.
• Can I use the REF5040 as a voltage reference for an ADC?
  Yes, the REF5040 is suitable for use as a voltage reference for analog-to-digital converters (ADCs). Its low noise and high accuracy make it a good choice for this application.
• How does temperature affect the REF5040's output voltage?
  The REF5040's output voltage has a temperature coefficient of ±10 ppm/°C, which means that the output voltage changes by ±10 ppm (parts per million) for every 1°C change in temperature.
