• DAC is a device that converts digital numbers
(binary) into an analog voltage or current output.

3. DAC V/s ADC
• ADCs are used in systems to capture “real world”
signals and convert them to “digital” signals.
• DACs are used in systems to capture “digital”
signals and convert them to “real world” signals
that humans can interpret.

4. Significance of Reference Voltage in DACs
• DACs use input reference voltage to generate
analog output from digital signals.
