DescriptionThe PCM67P dual 18-bit DAC are low cost, dual output 18-bit BiCMOS digital-to-analog con-verters utilizing a novel architecture to achieve excel-lent 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 PCM67P achieve high resolution, minimal glitch, and low zero-crossing distortion.
PCM67P 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 PCM67P operate from a single +5V supply. The low power consumption and small size (16-pin PDIP or 20-pin SOIC) make these converters ideal for a variety of digital audio applications.
