DESCRIPTION
The CE2836 is a mixed signal CMOS monolithic audio
Codec. It contains six multi-bit sigma delta DAC and a
stereo ADC with 5 input multiplexer, Ideal for audio
playback and recording applications.
The DAC consists of 128-time interpolation filters, 3
rd
order multi-bit
Σ∆
modulators, switch capacitors and
analog reconstruction filters. The
Σ∆
converter offers
superior differential linearity, with minimum distortion due
to component mis-match. high tolerance to clock jitter.
Additionally it includes separated digital volume control
for each channel.
The ADC utilizes cascaded
Σ∆
architecture. The internal
digital filter has a 20K bandwidth. It support sampling
frequency up to 96K Hz. The ADC also includes a analog
Automatic Level Control and Noise Gate function to ease
the recording applications.
