8 V  Popguard® Technology 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.
Six fully differential, or single-ended, inputs are available on stereo ADC1, ADC2, and ADC3.
When operating in Single-Ended Mode, an internal MUX before ADC3 allows selection from up to four single-ended inputs.
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.
The CDB42448 Customer Demonstration Board is also available for device evaluation and implementation suggestions.
Please refer to “Ordering Information” on page 65 for complete ordering information.
The CS42448 is ideal for audio systems requiring wide dynamic range, negligible distortion and low noise, such as A/V receivers, DVD receivers, and automotive audio systems.
