Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the range of 4.5V to 5.5V.
   • The reference voltage (VREF) should be between 2.5V and 5.0V.

2. Output Configuration:

   • The output voltage range is from 0V to the reference voltage (VREF).
   • For optimal performance, ensure the load resistance (RL) is at least 2kΩ.

3. Resolution:

   • The AD7226KR has a 12-bit resolution, providing high precision in digital-to-analog conversion.

4. Linearity:

   • The differential nonlinearity (DNL) and integral nonlinearity (INL) are both ±1 LSB, ensuring accurate and consistent output.

5. Settling Time:

   • The settling time is 10 μs when using a 2kΩ load resistance. This is the time it takes for the output to stabilize after a change in the input code.

6. Power Consumption:

   • The device consumes approximately 3 mA of current when all outputs are off and the supply voltage is 5V.

7. Temperature Range:

   • The operating temperature range is from -40°C to +85°C, making it suitable for a wide range of environmental conditions.

8. Handling and Storage:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).
   • Store the device in a dry, cool place to prevent moisture damage.

9. Connection Diagram:

   • Refer to the datasheet for the pin configuration and connection diagram to ensure proper wiring and functionality.

10. Programming:

    • Use the appropriate control signals and data lines to program the device. Refer to the datasheet for specific programming sequences and timing diagrams.
