Did you know?
The variable unit16_t dac_value + 0x0800, when written by software to the DAC channel used in 12-bit right-aligned mode, determines the DAC output voltage. To calculate the DAC output voltage, we need to consider that the DAC reference voltage is 3.0V. To determine the exact output voltage, we first need to convert the 12-bit value to a decimal number. The hexadecimal value represented by + 0x0800 is 2048 in decimal.
Next, we divide this decimal value (2048) by the maximum 12-bit value, which is 4096 (2^12). This division yields 0.5.
Finally, we multiply this result (0.5) by the DAC reference voltage of 3.0V. Thus, the DAC output voltage would be 1.5V.
By using this calculation method, we can determine the DAC output voltage accurately.
