CS42448(2005) データシート - Cirrus Logic

GENERAL DESCRIPTION
   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 Singleended 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.
