The output is generated through this Summing Amplifier Circuit. These resistors are connected across the inputs and the summing point.

In this type of Converter, every digital input bit that needs to be converted, requires one resistor or current source. Delta-Sigma DAC Binary Weighted Resistor D/A Converter Circuit.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. 1 – Introduction to Digital to Analog Converter What is Digital to Analog Converter (DAC)ĭigital to Analog Converter (DAC) basically converts digital code that represents digital value to analog current or voltage.įig. This post will discuss in detail about what is Digital to Analog Converter (DAC), it’s types, how it works, applications, advantages and disadvantages. Digital to Analog Converter (DAC) is an integrated circuit that converts digital signal to analog voltage/current which is necessary for further Analog Signal Processing.
