122 dB, 24-Bit, 192 kHz D/A Converter

The CS43122 is a complete, high-performance, 24 bit- 192 kHz, stereo, digital-to-analog conversion system. The device includes a digital interpolation filter followed by an oversampled, 5-bit Delta-Sigma modulator which drives second-order Dynamic-Element-Matching (DEM) selection logic. The output from the DEM block controls the input to a multi-element switched capacitor DAC/low-pass filter with fully-differential outputs. This multi-bit architecture features significantly lower out-of-band noise and jitter sensitivity than traditional 1-bit designs. The advanced second generation DEM guarantees low noise and distortion at all signal levels.

The CS43122 is the optimal D/A converter solution for any application that requires the highest performance and best possible sound quality. It is ideal for high-end consumer and professional audio products including universal DVD players, A/V receivers, outboard D/A converters, CD players, and mixing consoles.
