The device operates from a single +5 V power supply, and features low power con- sumption. Selectable de-emphasis filter for 32, 44.1, and 48 kHz sample rates is also included. The CS4221 also includes an analog volume control ca- pable of 113.5 dB attenuation in 0.5 dB steps. The analog volume control architecture preserves dynamic range during attenuation. Volume control changes are implemented using a “soft” ramping or zero crossing technique. Applications include digital effects processors, DAT, and multitrack recorders.
