Cirrus Logic, Inc. 114 dB, 24-bit, 192 kHz, 8-Channel D/A Converters with DSD Support and Low-Latency Digital Filtering CS4382A

The CS4362A/82A are pin compatible 6 and 8-channel audio digital/analog converters (DAC) featuring digital de-emphasis, one dB step size volume control, ATAPI channel mixing, and selectable fast and slow digital interpolation filters. The CS4362A/82A accepts 4 kHz to 216 kHz, PCM data sample rates and includes an over sampled, multi-bit Delta Sigma modulator which includes mismatch shaping technology that eliminates distortion due to capacitor mismatch. Following this stage is a multi-element switched capacitor stage and low-pass filter with differential analog outputs. The CS4362A/82A family also has a proprietary DSD processor which allows for 50 kHz on-chip filtering without an intermediate decimation stage.
