Description

The CS4222 is a highly integrated, high performance,

20-bit, audio codec providing stereo analog-to-digital

and stereo digital-to-analog converters using delta-sig-

ma conversion techniques. The device operates from a

single +5 V power supply, and features low power con-

sumption. A selectable de-emphasis filter for 32, 44.1,

and 48 kHz sample rates is also included.

The CS4222 also includes an analog volume control ca-

pable 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 instru-

ments, DAT, and multitrack recorders.

The CS4222 is packaged in a 28-pin plastic SSOP.
