Instructions for Use:

1. Power Supply Connection:

   • Connect VDD to the positive supply voltage (+15V).
   • Connect GND to the ground.

2. Reference Voltage Setup:

   • Apply the desired reference voltage (VREF) to the VREF pin. Ensure it is within the range of 0 to 15V.

3. Serial Data Input:

   • The device accepts serial data through the DIN pin. Ensure proper synchronization using the clock (CLK) and load (LDAC) signals.

4. Data Loading:

   • To load new data into the DAC register, ensure that the LDAC signal is active (low). After transferring the 8-bit data word, bring LDAC high to update the DAC output.

5. Output Configuration:

   • The analog output voltage will be proportional to the digital input code and the reference voltage. The relationship is given by: VOUT = (Digital Code / 256) * VREF.

6. Temperature Considerations:

   • Operate the device within the specified temperature range (-40°C to +85°C) to ensure reliable performance.

7. Handling Static Electricity:

   • Handle with care to avoid damage from static electricity, especially when soldering or handling in a dry environment.

8. Storage Conditions:

   • Store in a dry place away from direct sunlight and extreme temperatures to prevent degradation of performance.
