D/A Converters CS4365/85

The ICs accept 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 televisions, mixing consoles, effects processors, sound cards and automotive audio systems.

The CS4365/85 are available in a 48-pin LQFP package in both commercial (-40 degrees to +85 degrees C) and automotive grades (-40 degrees to +105 degrees C). The CDB4365/85 Customer Demonstration Boards are also available for evaluation.

They feature a proprietary DSD processor which allows for volume control and a 50 kHz on-chip filtering with an intermediate decimation stage. It also offers an optional path for direct DSD conversion by directly using the multielement switched capacitor array.

The CS4365/85 are pin-compatible 6- and 8+-channel digital-to-analog systems. They feature digital de-emphasis, half-DB step-size volume control, ATAPI channel-mixing, selectable fast and slow digital interpolation filters followed by an oversampled, multibit Delta-Sigma modulator which includes mismatch shaping technology that eliminates distortion due to capacitor mismatch. Following this stage is a multielement switched capacitor stage and low-pass filter with differential analog outputs.
