Description

The CS4362A is a complete 6-channel digital-to-analog system. This D/A system includes digital de-emphasis, one-dB step size volume control, ATAPI channel mixing, selectable fast and slow digital interpolation filters followed by an oversampled, 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 also has a proprietary DSD processor which allows for 50 kHz on-chip filtering without an intermediate decimation stage.

The CS4362A accepts PCM data at sample rates from 4 kHz to 216 kHz, DSD audio data, and delivers excellent sound quality. These features are ideal for multichannel audio systems including SACD players, A/V receivers, digital TV’s, mixing consoles, effects processors, sound cards and automotive audio systems.
