CS4224

24-Bit 105 dB Audio Codec with Volume Control

Features

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-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.

l 105 dB Dynamic Range A/D Converters

l 105 dB Dynamic Range D/A Converters

l 110 dB DAC Signal-to-Noise Ratio (EIAJ)

l Analog Volume Control (CS4224 only)

l Differential Inputs / Outputs

l On-chip Anti-aliasing and Output Smoothing

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.

Filters

l De-emphasis for 32, 44.1 and 48 kHz

l Supports Master and Slave Modes

l Single +5 V power supply

l On-Chip Crystal Oscillator

l 3 - 5 V Digital Interface

Applications include digital effects processors, DAT, and

multitrack recorders.
