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, 4^th order ∆ modulators, switch capacitors and analog reconstruction filters. The one bit ∆ converter offers superior differential linearity, with no distortion due to component mis-match. high tolerance to clock jitter.

The CE2746 support data conversion from 32K to 192KHz. The analog section operates at 5 volt while the digital section at 3.3 volt. This dual voltage system reduces not only the power consumption but also the noise caused by the digital circuit switching. The CE2746 is ideal for DVD player, AV receiver and set-top box application.

The CE2746 support 24, 20, 18 and 16-bit input data. It also support multiple sampling frequency data. Each DAC has its own individual volume control.
