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.
FEATURES
• Stereo Audio ADC.
- 96dB SNR (A Weighted).
- -82 dB THD + N Ratio (A Weighted).
- 32K - 96 KHz. Sampling Rates.
- 91 dB channel separation.
• I2S, Left Justified Digital I/F Formats.
• 3.3 Volt Power Supply.
Applications
• Digital Surround Sound For Home Theatre
• AV Receiver
• Car Audio.
