1 / 52 page Features • 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 General Description 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.
