DESCRIPTION

The PCM67 and PCM69A 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 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 (16-

pin PDIP or 20-pin SOIC) make these converters ideal

for a variety of digital audio applications.
