Description
The CS5126 CMOS analog-to-digital converter is an ide-
al front-end for stereo or monaural digital audio systems.
The CS5126 can be configured to handle two channels
at up to 50 kHz sampling per channel, or it can be con-
figured to sample one channel at rates up to 100 kHz.
The CS5126 executes a successive approximation algo-
rithm using a charge redistribution architecture. On-chip
self-calibration circuitry has 18-bit resolution thus avoid-
ing any degradation in performance with low-level
signals. The charge redistribution technique also pro-
vides an inherent sampling function which avoids the
need for external sample/hold amplifiers.
Signal-to-(noise+distortion) in stereo operation is 92 dB,
and is dominated by internal broadband noise (1/2 LSB
rms). When the CS5126 is configured for 2X oversam-
pling, digital post-filtering bandlimits this white noise to
20 kHz, increasing dynamic range to 95 dB.
