Ordering Information: CS4215-KL 0°C to 70°C CS4215-KQ 0°C to 70°C CDB4215 Evaluation Board 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.

Notes: 1. This specification is guaranteed by characterization, not production testing. 2. Very low frequency signals will be slightly distorted when using the HPF. 3. Input resistance is for the input selected. Non-selected inputs have a very high (>1M Ω) input resistance. 4. DC current only. If dynamic loading exists, then CMOUT must be buffered or the performance of ADC’s and DAC’s may be degraded. * Parameter definitions are given at the end of this data sheet.
