REF02AP Frequently Asked Questions (FAQs)

  • The REF02AP should be placed close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is referencing, and the input and output pins should be routed separately to minimize noise coupling. A ground plane or shielded enclosure can also help reduce electromagnetic interference (EMI).
  • A 0.1 μF to 1 μF ceramic capacitor should be placed as close as possible to the REF02AP's input pin (VIN) to decouple the voltage reference from the power supply. An additional 10 μF to 22 μF capacitor can be added in parallel to further filter out noise.
  • The REF02AP's voltage reference accuracy is affected by temperature, with a typical temperature coefficient of ±5 ppm/°C. This means that for every 1°C change in temperature, the voltage reference will change by ±5 ppm. This can be compensated for using temperature sensing and correction techniques.
  • While the REF02AP can be used as a voltage regulator, it is not designed for high-current applications. The maximum output current is limited to 10 mA, and the device is not intended for use as a general-purpose voltage regulator. It is primarily designed as a voltage reference for ADCs and DACs.
  • The REF02AP requires a power supply voltage between 4.5 V and 18 V, with a recommended operating voltage of 5 V or 15 V. The device can operate with a wide range of power supply voltages, but the voltage reference accuracy may be affected by power supply noise and ripple.
