The CS4222 is a highly integrated, high-performance, 20-bit audio CODEC that provides stereo analog-to-digital (A/D) and stereo digital-to-analog (D/A) converters that use Delta-Sigma conversion techniques. Operating from a single 5 V power supply, the device is notable for its low power consumption. A selectable de-emphasis filter for 32 kHz, 44.1 kHz, and 48 kHz sample rates is also included. The CS4222 also includes an analog volume control capable of 113.5 dB attenuation in 0.5 dB resolution. 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 reverb processors, musical instruments, DAT (digital audio tape), and multitrack recorders. |
