Digital to analog converter is an electronic circuit that converts any digital signal (such as binary signal) into an analog signal (voltage or current). The digital signal such as the binary signal exist in the form of bits & it is the combination of 1’s & 0’s (or High & low voltage levels). The word “source” is used generically to refer to the transistor circuit structure, which may either source or sink current. Instead of rapidly toggling a digital pin high or low to generate an output signal, we will be using an external digital to analog converter (DAC for short) for more control over the signal. The main purpose of the A/D converters within a data acquisition system is to convert conditioned analog signals into a stream of digital data so that the data acquisition system can process them for display, storage, and analysis. In the circuit of Figure 6.5, the input common-mode voltage is set by V1, which level shifts the amplifier output to the correct value. main space for any arbitrary mixed integer/Boolean ex-pression.
