CE2766
6-Channel Audio DAC, 24-bit, 192kHz
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

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.

INFINITE ZERO DETECTION
The CE2766 has an Infinite Zero Detection circuit which detects zero in the Audio Serial Port that lasts for approximately 0.1
sec. By default, the zero detection circuit is on.
Serial Command Port
The user can select the chip operation mode by programming the internal control registers through serial I2C port. The Chip
Address for the CE2766 is 35H. The protocol for write operation consists of sending 3 byte data to CE2766, following each
byte is the acknowledges generated by CE2766. The first byte is the 7-bit Chip Address followed by the read/write bit (read is
high, write is low). The second byte is the control register address. The third byte is the control register data.
Upon power up, all programmable registers are set to default values. Figure 2 describes the serial command port timing

Example
Set channel 1L volume to 30H:
first byte: [CA R/W] = 6AH
( Note: Chip adrress: CA<6:0> = 35H, R/W =0.)
second byte: register address: A<7:0> = 02H
third byte: data D<7:0> = 30H

Notes:
1. Absolute maximum ratings are limiting values applied individually, while all other parameters are within specified
operating conditions.
2. Applied voltage must be current limited to specified range, and measured with respect to VSS.
3. Forcing voltage must be limited to specified range.
4. Current is specified as conventional current, flowing into the device.
