Description
The CS4220/1 is a highly integrated, high performance,
24-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. 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.
