20-Bit Stereo Audio Codec with Volume Control

Features

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.

99 dB Dynamic Range

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

Analog Volume Control

- 0.5 dB Step Resolution

- 113.5 dB Attenuation

Soft Mute Capability

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.

Differential Inputs/Outputs

On-chip Anti-aliasing and Output Smoothing

Filters

De-emphasis for 32, 44.1 and 48 kHz

Stand-Alone or Control Port Mode

Single +5 V power supply

Applications include reverb processors, musical instru-

ments, DAT, and multitrack recorders.

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