Working Principles

The DAC8830ICD utilizes a 16-bit digital input code to generate an analog output voltage. It employs a resistor ladder network and a switching mechanism to convert the digital input into a corresponding analog voltage. The internal reference voltage sets the maximum output voltage, which can be adjusted by the user.

When a digital input code is received, the DAC8830ICD converts it into an analog voltage proportional to the input code. This analog voltage appears at the OUT pin and can be used as a precise control signal in various applications.
