CS4384 Datasheet | Cirrus Logic

Features ! Advanced Multi-bit Delta Sigma Architecture ! 24-bit Conversion ! Automatic Detection of Sample Rates up to Description The CS4384 is a plete 8-channel digital-to-analog system. This D/A system includes digital de-emphasis, half-d B 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 single-ended analog outputs. The CS4384 also has a proprietary DSD processor which allows for volume control and 50 k Hz on-chip filtering without an intermediate decimation stage. It also offers an optional path for direct DSD conversion by directly using the multi-element switched capacitor array. The CS4384 accepts PCM data at sample rates from 4 k Hz to 216 k Hz, 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. This product is available in 48-pin LQFP package and is available in both Automotive (-40° C - +85° C) and mercial (-10° C - +70° C) temperature grades.
