The device operates from a sin- gle +5 V power supply, and features low power consumption. Selectable de-emphasis filter for 32, 44.1, and 48 kHz sample rates is also included. The CS4224 includes an analog volume control capable of 113.5 dB attenuation in 0.5 dB steps. The analog vol- ume control architecture preserves dynamic range during attenuation. Volume control changes are imple- mented using a “soft” ramping or zero crossing technique. Applications include digital effects processors, DAT, and multitrack recorders.
