Audio Data Coding
The CS4215 is a single-chip, stereo, CMOS multime-
dia
codec
that
supports
CD-quality
music,
Programmable Gain for Analog Inputs
FM radio-quality music, telephone-quality speech, and
Programmable Attenuation for Analog
Outputs
On-chip Oscillators
+5V Power Supply
Microphone and Line Level Analog Inputs
Headphone, Speaker, and Line Outputs
On-chip Anti-Aliasing/Smoothing Filters
Serial Digital Interface

modems. The analog-to-digital and digital-to-analog
converters are 64×oversampled delta-sigma converters
with on-chip filters which adapt to the sample fre-
quency selected.
The +5V only power requirement makes the CS4215
ideal for use in workstations and personal computers.
Integration of microphone and line level inputs, input
and output gain setting, along with headphone and
monitor speaker driver, results in a very small footprint.
