DESCRIPTION

The CE2746 is a mixed signal CMOS monolithic audio digital to analog converter. It contains six 1-bit sigma delta DAC. The system consists of 128-time interpolation filters, 4th order Σ∆ modulators, switch capacitors and analog reconstruction filters. The one bit Σ∆ converter offers superior differential linearity, with no distortion due to component mis-match. high tolerance to clock jitter.
