20.1 | Introduction

Digital to Analog Converter (DAC) and Analog to Digital Converter (ADC) are widely used in control operations and instrumentation in industries. As their names suggest, a DAC is to convert a digital input to its proportionate analog form. Converting any analog input signal to its proportionate digital form is the job of any ADC. In this chapter, we will discuss how a DAC or ADC can be interfaced with 8051 microcontroller. Because of ...
