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° to +70°) and Automotive (-40° to
+105°) grades. The CDB42448 Customer Demonstra-
tion board is also available for device evaluation and
implementation suggestions. Please refer to
“Ordering
Information” on page 64
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.
