REF102CP Frequently Asked Questions (FAQs)

  • The REF102CP should be placed close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is supplying, and the input and output pins should be routed separately to minimize noise coupling. A ground plane under the device is also recommended to reduce noise.
  • To ensure stability, a 10uF capacitor should be connected between the output pin and ground, and the device should be decoupled from the power supply with a 10uF capacitor and a 1kΩ resistor in series.
  • The power-up sequence should be: 1) Apply power to the REF102CP, 2) Wait for the REF102CP to settle (typically 10ms), and 3) Apply power to the ADC or DAC.
  • The total error budget includes the initial accuracy, temperature coefficient, and long-term stability. Calculate the total error budget by adding the absolute values of these three components.
  • Yes, the REF102CP can be used as a voltage reference for a ratiometric ADC. However, the REF102CP's output voltage should be divided down to match the ADC's input range, and the REF102CP's output impedance should be considered when designing the divider circuit.
