Cirrus Logic CS42448

The CS42448 CODEC provides six multi-bit analog-to-digital and eight multi-bit digital-to-analog delta-sigma converters. The CODEC is capable of operation with either differential or single-ended inputs and outputs, in a 64-pin LQFP package. When operating in Single-Ended Mode, an internal MUX before ADC3 allows selection from up to four single-ended inputs.

 Six 24-bit A/D, Eight 24-bit D/A Converters  ADC Dynamic Range – 105 dB Differential – 102 dB Single-Ended  DAC Dynamic Range – 108 dB Differential – 105 dB Single-Ended  ADC/DAC THD+N – -98 dB Differential – -95 dB Single-Ended  Compatible with Industry-Standard Time Division Multiplexed (TDM) Serial Interface  System Sampling Rates up to 192 kHz  Programmable ADC High-Pass Filter for DC Offset Calibration  Logarithmic Digital Volume Control  I²C™ & SPI™ Host Control Port  Supports Logic Levels Between 5 V and 1.8 V  Popguard® Technology Six fully differential, or single-ended, inputs are available on stereo ADC1, ADC2, and ADC3. Digital volume control is provided for each ADC channel, with selectable overflow detection. All eight DAC channels provide digital volume control and can operate with differential or single-ended outputs. An auxiliary serial input is available for an additional two channels of PCM data. The CS42448 is available in a 64-pin LQFP package in Commercial (-10°C to +70°C) and Automotive (-40°C to +105°C) grades.
