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.
