PCM67U Overview
The PCM67 and PCM69A dual 18-bit DAC are low cost, dual output 18-bit BiCMOS digital-to-analog converters utilizing a novel architecture to achieve excellent low level performance. By bining 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...
