Binary ladder or R–2R ladder D/A Converter Circuit.Binary Weighted Resistor D/A Converter Circuit.
There are basically four types of Digital to Analog Converter circuits namely: 2 – Block Diagram of Digital to Analog Converter (DAC) Types of Digital to Analog Converter (DAC) The digital inputs are d 0, d 1, d n-2, d n-1 and V a is the output Analog Voltage.įig.
Analog signal is necessary to drive Motors, temperature controller etc.įig.2 shows a block diagram of DAC circuit which shows n-bit digital inputs converted to Analog Signal. This digital signal is converted back to Analog signal for further processing i.e. In any communication system, the analog signal which is in the form of physical variables is converted to digital value by ADC.
