Texas Instruments PCM69AU-K

Description
The PCM67 and PCM69A are dual 18-bit BiCMOS digital-to-analog converters (DACs) that utilize a novel architecture to achieve excellent low-level performance. They combine 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. This combination results in high resolution, minimal glitch, and low zero-crossing distortion.
The PCM67 has a digital offset at bit 9, making it ideal for high-performance CD players. The PCM69A has a digital offset 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 and have low power consumption. They are available in space-saving 16-pin PDIP or 20-pin SOIC packages.
