DACs are most easily understood by examining a simplified DAC block diagram As shown in Figure 1 the architecture of a onechannel DAC consists of a resistor array each of equal value R followed by a railtorail voltage output amplifier The voltage a. This article explores the topic more deeply by analyzing gain and noise The fully differential amplifier has multiple feedback paths and circuit analysis requires close attention to detail Care must be taken to include the OCM pin for a complete ana 114 AD Converters ADCs perform two basic fundamental operations discretiza tion in time and discretization in amplitude e two functions are shown con ceptually in Figure 1 though the actual ADCmay not be structure as such 1 e rst operation of the These operating ranges may be broad and in some cases may overlap It is usually not possible to derive any arbitrary output voltage from the entire range of permissible input voltages There are several factors that can cause this including the inter Keith Weaver.
