CS4220/21 General Description



The CS4220 and CS4221 are highly integrated, high-performance, 24-bit audio CODECs that provide 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 CS4220/21 devices are notable for their low power consumption. A selectable de-emphasis filter for 32 kHz, 44.1 kHz, and 48 kHz sample rates is also included.

The CS4221 also includes an analog volume control capable 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 (digital audio tape), and multitrack recorders.
