In a 12-bit right-aligned DAC, the digital code is converted directly to the output voltage.
The reference voltage is given as 3.0V.
Since this is a 12-bit DAC, it can represent 2^12 = 4096 different codes.
The step size or resolution of the DAC can be calculated as:
Reference Voltage / Total Number of Codes
= 3.0V / 4096
= 0.000732 V/code
For a given digital code, the output voltage can be calculated as:
Output Voltage = Digital Code * Step Size
Let's assume the specified digital code is 1023. Plugging in the values:
Output Voltage = 1023 * 0.000732 V/code
= 0.74928 V
Therefore, the DAC output voltage for the specified digital code in 12-bit right-aligned mode with a reference voltage of 3.0V is approximately 0.74928V.
