CS4223 CS4224 24-Bit 105 dB Audio Codec with Volume Control Features 105 dB Dynamic Range A/D Converters 105 dB Dynamic Range D/A Converters 110 dB DAC Signal-to-Noise Ratio (EIAJ) Analog Volume Control (CS4224 only) Differential Inputs / Outputs On-chip Anti-aliasing and Output Smoothing Filters De-emphasis for 32, 44.1 and 48 kHz Supports Master and Slave Modes Single +5 V power supply On-Chip Crystal Oscillator 3 - 5 V Digital Interface 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 single +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 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.
