»L’escursione dinamica DR, dall’inglese dynamic range, è il rapporto tra il più grande e il più piccolo valore (escluso lo 0) dei segnali d’uscita, espresso in decibel. Per un DAC lineare ad n bit l’escursione dinamica vale 6n dB. »The dynamic range DR is the ratio between the biggest and the smaller value (excluding 0) of the output signals, expressed in decibels. For a linear n bit DAC the dynamic range is 6n dB. Escursione dinamica

»I principali formati dei segnali digitali sono NRZ (Non Return To Zero), RZ (Return to Zero), Bifase, AMI (Alternate Mark Inversion), Manchester. »The main digital signal formats are NRZ (Non Return to Zero), RZ (Return to Zero), biphase, AMI (Alternate Mark Inversion), Manchester. Formati dei segnali digitali

»L’interfaccia analogica dei moderni DAC realizza l’uscita producendo segnali di tensione o di corrente. »The analog interface of modern DAC produces output signals by voltage or current. Interfaccia analogica dei DAC

»Le interfacce d’ingresso e d’uscita possono essere seriali o parallele. »The input and output interfaces may be serial or parallel. Interfacce seriali e parallele

»Il modo più semplice per usare un convertitore è quello denominato free running. »The easiest way to use a converter is called free running. Free running

»Il bus I 2 C è una delle interfacce seriali più usate. »The I 2 C bus is one of the most popular serial interfaces. Bus I 2 C
