    Analog value processing Conversion method Conversion An integrated analog-to-digital converter converts the analog signal into a digital signal in order that the compact CPU can process the analog signal read in by an analog channel. Once the CPU has processed the digital signal, an integrated digital-to-analog converter converts the output signal into an analog current or voltage value.
