GENERAL DESCRIPTION
The CS42888 CODEC provides four 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.
Four fully differential, or single-ended, inputs are avail-
able on stereo ADC1 and ADC2. Digital volume control
is provided for each ADC channel, with selectable over-
flow 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 CS42888 is available in a 64-pin LQFP package in
Commercial (-10° to +70°) and Automotive (-40° to
+105°) grades. The CDB42888 Customer Demonstra-
tion board is also available for device evaluation and
implementation suggestions. Please refer to “Ordering
Information” on page 61 for complete ordering
information.
The CS42888 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.
