DESCRIPTION
The PCM67 and PCM69A dual 18-bit DAC are low cost, dual output 18-bit BiCMOS digital-to-analog converters utilizing a novel architecture to achieve excellent low level performance. By combining a conventional thin-film R-2R ladder DAC, a digital offset technique with analog correction and an advanced one-bit DAC using first order noise shaping technique, the PCM67 and PCM69A achieve high resolution, minimal glitch, and low zero-crossing distortion. PCM67 digital offset occurs at bit 9, making it ideal for high-performance CD players. PCM69A digital offset occurs at bit 4, making it an excellent choice for digital musical instruments and audio DSP. Both PCM67 and PCM69A operate from a single +5V supply. The low power consumption and small size (16pin PDIP or 20-pin SOIC) make these converters ideal for a variety of digital audio applications.
