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 ei-

ther differential or single-ended inputs and outputs, in a

64-pin LQFP package.

Six fully differential, or single-ended, inputs are avail-

able on stereo ADC1, ADC2, and ADC3. When

operating in Single-Ended Mode, an internal MUX be-

fore 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 Demonstra-

tion board is also available for device evaluation and

implementation suggestions. Please refer to

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.
