Overview
Microelectronics DESCRIPTION The CE2766 is a mixed signal CMOS monolithic audio digital to analog converter.
It contains six multi-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 www.

com offers superior differential linearity, with no distortion due to component mis-match.
high tolerance to clock jitter.
The CE2766 support data conversion from 32K to 192KHz.
The chip is operated at 3.
3 volt to simplify the power requirement.
The CE2766 is ideal for DVD player, AV receiver and set-top box application.
The CE2766 support 32, 24, 20 and 16-bit input data.
It also support multiple sampling frequency data.
Each DAC has its own individual volume control.
