Description
The CS4223/4 is a highly integrated, high performance,
24-bit, audio codec providing stereo analog-to-digital and
stereo digital-to-analog converters using delta-sigma
conversion techniques. 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.
