Instructions for Use:

1. Power Supply:

   • Ensure the input voltage (V_IN) is within the specified range of 2.7V to 5.5V.
   • The REF198G can operate with a supply current of up to 150μA.

2. Output Voltage:

   • The output voltage (V_OUT) is fixed at 2.048V and should be stable under varying conditions.

3. Load Regulation:

   • The load regulation is very low, typically 0.0005% per milliampere of load current. This ensures minimal change in output voltage with varying load.

4. Temperature Effects:

   • The temperature coefficient (TCV_OUT) is 5 ppm/°C, indicating that the output voltage will change by 5 parts per million for each degree Celsius change in temperature.

5. Initial Accuracy:

   • The initial accuracy of the output voltage is ±0.1%, which means the output voltage can vary by ±0.002048V from the nominal 2.048V at room temperature (25°C).

6. Noise:

   • The output noise is very low, typically 3 μVrms over the frequency range of 0.1Hz to 10Hz.

7. Operating and Storage Temperature:

   • The device can operate within a temperature range of -40°C to 85°C and can be stored between -65°C and 150°C.

8. Handling:

   • Handle the device with care to avoid static damage. Use appropriate ESD protection when handling the device.

9. Mounting:

   • Ensure proper mounting and soldering techniques to avoid thermal and mechanical stress on the device.

10. Circuit Design:

    • Use bypass capacitors (typically 0.1μF and 10μF) close to the power pins to ensure stability and reduce noise.

11. Testing:

    • Before finalizing the design, test the circuit under various operating conditions to ensure it meets the required performance specifications.
