CE2752

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.
