The PCM67 and PCM69A dual 18-bit DAC are lowcost, dual output 18-bit BiCMOS digital-to-analog convertersuTIlizing a novel architecture to achieve excellentlow level performance.By combining a convenTIonal thin-film R-2R ladderDAC, a digital offset technique with analog correcTIonand an advanced one-bit DAC using first order noiseshaping technique, the PCM67 and PCM69A achievehigh resoluTIon, minimal glitch, and low zero-crossingdistortion.PCM67 digital offset occurs at bit 9, making it ideal forhigh-performance CD players. PCM69A digital offsetoccurs at bit 4, making it an excellent choice for digitalmusical instruments and audio DSP.Both PCM67 and PCM69A operate from a single +5Vsupply. The low power consumption and small size (16-pin PDIP or 20-pin SOIC) make these converters idealfor a variety of digital audio applications.
