15-Bit Resistor DAC Output Formula

1. Introduction Today, I derived the output formula for an 8-bit resistor DAC, calculating the impact of the microcontroller’s IO port resistance on the DAC’s linear accuracy. Now that I have some time left, I will patiently derive the analytical formula for the output voltage of a 15-bit DAC to verify whether the microcontroller’s IO … Read more
