Instructions for Using REF194GP

  1. Supply Voltage (VCC):

    • Ensure the supply voltage is within the range of 2.7V to 5.5V.
    • Use a stable power source to avoid fluctuations that can affect the output voltage.
  2. Output Voltage (VOUT):

    • The REF194GP provides a precise 2.048V reference voltage under no load conditions.
    • Connect the output to the required circuitry, ensuring the load current does not exceed 10mA.
  3. Line Regulation:

    • The line regulation is very low, indicating minimal changes in output voltage with variations in supply voltage.
    • This makes the REF194GP suitable for applications where the supply voltage may vary.
  4. Load Regulation:

    • The load regulation is also very low, ensuring the output voltage remains stable even when the load current changes.
    • Keep the load current within the specified range to maintain accuracy.
  5. Temperature Coefficient:

    • The temperature coefficient is 10 ppm/°C, meaning the output voltage will change by 10 parts per million for each degree Celsius change in temperature.
    • Consider the operating temperature range (-40°C to +85°C) when designing your application.
  6. Output Noise Voltage:

    • The output noise voltage is 3 μVRMS over the frequency range of 0.1Hz to 10Hz.
    • Use appropriate filtering techniques if lower noise is required.
  7. Dropout Voltage:

    • The dropout voltage is 1V, which means the input voltage must be at least 1V higher than the output voltage to ensure proper operation.
    • Ensure the supply voltage is sufficient to maintain this condition.
  8. Quiescent Current:

    • The quiescent current is 150 μA, which is relatively low and helps in reducing power consumption.
    • This is important for battery-powered applications.
  9. Short-Circuit Current:

    • The short-circuit current is limited to 30 mA, providing built-in protection against short circuits.
    • However, it is recommended to include additional protective measures in the circuit design.
  10. Handling and Storage:

    • Handle the REF194GP with care to avoid static damage.
    • Store in a dry, cool place to prevent moisture damage.

By following these parameters and instructions, you can ensure optimal performance and reliability of the REF194GP voltage reference in your application.
