This section discusses about these two types of DACs in detail − Weighted Resistor DACĪ weighted resistor DAC produces an analog output, which is almost equal to the digital (binary) input by using binary weighted resistors in the inverting adder circuit. In general, the number of binary inputs of a DAC will be a power of two. The block diagram of DAC is shown in the following figure −Ī Digital to Analog Converter (DAC) consists of a number of binary inputs and a single output. This chapter deals with Digital to Analog Converters in detail. The digital signal is represented with a binary code, which is a combination of bits 0 and 1. A Digital to Analog Converter (DAC) converts a digital input signal into an analog output signal.
