Overview
Microelectronics DESCRIPTION The CE2752 is a mixed signal CMOS monolithic audio digital to analog converter.
It contains dual multi-bit sigma delta DAC.
The system consists of 128-time interpolation filters, 3th order multi-bit Σ∆ modulators, switch capacitors and analog reconstruction filters.
The multi-bit Σ∆ converter offers high tolerance to clock jitter and linearity.
The CE2752 support data conversion from 32K to 192KHz.
This chip operates at 3.
3 volt to reduce the power consumption and the noise caused by the digital circuit switching.
The CE2752 is ideal for DVD player, AV receiver and set-top box application.
The CE2752 support 24, 20, 18 and 16-bit input data.
It also support sampling frequency up to 192K.
