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,

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.
