DESCRIPTION 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, and high tolerance to clock jitter. The internal digital filter has a 20K bandwidth. The analog input is 1 vrms corresponding to digital full scale value. The value greater than full scale will be clipped.
