Product Summary
The PCM69AU dual 18-bit DAC is a low cost, dual output 18-bit BiCMOS digital-to-analog converter 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 PCM69AU achieves high resolution, minimal glitch, and low zero-crossing distortion. The PCM69AU digital offset occurs at bit 4, making the PCM69AU an excellent choice for digital musical instruments and audio DSP. The PCM69AU operates from a single +5V supply. The low power consumption and small size (16-pin PDIP or 20-pin SOIC) make the PCM69AU ideal for a variety of digital audio applications.
