Instructions for Using REF194GP
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
