Description
The CS42L50 is a highly integrated, 24-bit, 96 kHz audio
codec.
This device is based on delta-sigma modulation allowing
infinite adjustment of the sample rate between 8 kHz and
100 kHz simply by changing the master clock frequency.
The CS42L50 contains a 2:1 stereo mux, progra
m
mable
analog gain control, and digital attenuation on the analog
inputs. The output D/A converters include digital bass
and treble boost, dynamic range compression, limiting,
mixing, volume control and de-emphasis.
The CS42L50 operates from a +1.8 V to +3.3 V supply.
These features are ideal for portable MP3 and MD re-
corders, CD and DVD recorders, digital camcorders, and
other portable systems that require extremely low power
consumption in a minimal amount of space.
