CS4215

Semiconductor Corporation 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 MwaveTM audio codec. The CS4215 is a single-chip, stereo, CMOS multimedia 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 frequency 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.
