This D/A system includes digital de-emphasis, half-dB step size volume control, ATAPI channel mix- ing, selectable fast and slow digital interpolation filters followed by an oversampled, multi-bit delta sigma mod- ulator which includes mismatch shaping technology that eliminates distortion due to capacitor mismatch. Follow- ing 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 kHz on-chip fil- tering without an intermediate decimation stage. It also offers an optional path for direct DSD conversion by di- rectly using the multi-element switched capacitor array. The CS4384 accepts PCM data at sample rates from 4 kHz to 216 kHz, DSD audio data, and delivers excel- lent sound quality. These features are ideal for multi- channel audio systems including SACD players, A/V re- ceivers, digital TV’s, mixing consoles, effects processors, and sound cards. This product is available in 48-pin LQFP package in Commercial (-40°C to +85°C) temperature grade. See “Ordering Information” on page 51 for complete details.
