16-Bit Stereo Audio Codec

Complete CMOS Stereo Audio Input General Description

and Output System featuring:

The CS4218 Stereo Audio Codec is a monolithic

CMOS device for computer multimedia, automotive,

and portable audio applications. It performs A/D and

D/A conversion, filtering, and level setting, creating 4

audio inputs and 2 audio outputs for a digital computer

system. The digital interfaces of left and right channels

are multiplexed into a single serial data bus with word

rates up to 50 kHz per channel.

Delta-Sigma A/D and D/A Converters using

64x Oversampling.

•

Input Anti-Aliasing and Output Smoothing

Filters.

Programmable Input Gain (0 dB to 22.5 dB).

•

ADCs and the DACs use delta-sigma modulation with

64X oversampling. The ADCs and DACs include digi-

tal decimation filters and output smoothing filters

on-chip which eliminate the need for external anti-alias-

ing filters.

Programmable Output Attenuation (0 dB to

46.5 dB).

Sample frequencies from 4 kHz to 50 kHz.

•

Low Distortion, THD < 0.02% for DAC.

THD < 0.02% for ADC.

The CS4218 is pin and function compatible with the

CS4216 when used in Serial modes 3 and 4. See the

Appendix A at the end of this data sheet for details.

Low Power Dissipation: 80 mA typical.

Power-Down Mode : 1 mA typical.

•

I S is a trademark of Philips.

Pin Compatible with CS4216 when used in

Serial Modes 3 and 4 (See Appendix A).

Ordering Information:

I S(TM) Compatible Serial Mode (SM5).
