CS4215
16-Bit Multimedia Audio Codec
Features
General Description
• Sample Frequencies from 4 kHz to 50 kHz
• 16-bit Linear, 8-bit Linear, µ-Law, or A-Law
Audio Data Coding
• Programmable Gain for Analog Inputs
• 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
The CS4215 is an Mwave^TM
audio codec.
The CS4215 is a single-chip, stereo, CMOS multime-
dia codec that supports CD-quality music,
FM radio-quality music, telephone-quality speech, and
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.
