ladderDAC and Delta-Sigm aDAC.The popular discrete ladder DAC design alows designers to use diferent com ponents for various parts of the circuit, providing greater flexibilty in tailoring the sound signature.However, the discrete ladder DACs can sufer from non-linearitiescaused byprecision mismatches in the resistor values. Uneven tem perature changesalso play a significant role in introducing non-linearity to the system . This can lead to distortion and reduced overal perform ance. Delta-Sigm a DACs are known fortheir high ac uracy and resolution,which is achieved through precise m anufacturing proces es.These DACs also oferahighdynam icrangeand low noise and distortion level,m aking them wel-suited for high quality music playback applications. However, Delta-Sigm aDACsare often integrated with com plicated digital circuits like
Phase LockLoop (PLL),digitalfilter,and oversam pling circuits,which can m ake them les custom isable for designers. This can limit their suitabilty for high-end applications where customisation and flexibilty are im portant. AURALiC's Fusion DAC design in the VEGA G2.2 and G3 products is a pioneering technology that com bines the bestfeaturesofdiscrete ladderand Delta-Sigma DAC designs. This innovative approach uses a high perform ance, m anufacturer DAC chip asa basisform odification.M ostofthe DAC chips’ functions, such as PLL, digitalfilter,and oversam pling circuits are bypas ed,and instead AURALiC's proprietary clock reconstruction,digital filter, and oversam pling technologies are deployed. This unique approach ensuresthatonly the precise switching network inside a DAC chip is used for the final digitalto- analog conversion
