CE2632 - CEI Microelectronics

CE2632 mixed signal CMOS monolithic stereo audio ADC

The CE2632 is a mixed signal CMOS monolithic stereo audio ADC for consumer applications. The ADC is 128-time oversampled. The sampled data are digital filtered and decimated before sent out. A switchabThe ADC utilizes 4-order Σ∆ architecture. The 1− bit Σ∆ converter offers superior differential linearity, with minimum distortion due to component mismatch, an.
