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.DataSheet4U.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.
