DESCRIPTION
●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 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.
